As with all VeloSolo products the Disc Cog is custom manufactured in England by the UK's leading international aftermarket motorcycle gear and sprocket engineering company with over 70 world champions riding its products.
Blanks are machined from EN36 cro-moly steel stock, teeth precision milled and cogs drilled to very tight tolerances before undergoing heat treatment. Bright nickel passivated and laser engraved for a beautiful finish. Very strong, very round and a perfect fit. Not to be confused with cheap laser cut or stamped cogs. Reversible without affecting chainline for even longer life.
We are confident these are the hardest wearing disc mount cogs available and guarantee the original purchase for life to the original owner. If you wear one out send it back and we will replace it with one of the same size free of charge (terms and conditions apply, see below*).
Available in 1/8" and 3/32" widths and 16, 17, 18, 19, 20, 21 teeth. Please see this page for sample weights of VS components. Please see FAQ for more information and set-up advice.
*Guarantee applies to the original owner only, cog must be run in both directions evenly and flipped frequently, postage costs not included, claims must be accompanied by the *original* paper proof of purchase, commercial use excluded, please contact us prior to return.
Exact same design as our regular cro-mo Disc cogs but machined from solid 7075-T6 heat-treated aluminium alloy, anodized and laser engraved. Less than half the weight of the equivilent steel cogs and available in a range of colours.
Note: being aluminium these are ultimately not as hard wearing as the cro-mo cogs so we are not able to offer a lifetime guarantee. However, these are in aircraft-grade heat-treated 7075 and as with our regular threaded 7075 track cogs we expect them to hold up very well to wear. They are of course reversible without affecting chainline so can be run in both directions.
Available in 1/8" width and now 3/32" too. Various colours include black, red & gold. Other colours discontinued. Please see this page for sample weights of VS components. Please see FAQ for more information and set-up advice.
Yes, we make standard threaded cogs too! As with our bolt-on cogs these traditional screw on threaded cogs are custom manufactured in England by the UK's leading motorcycle gear and sprocket engineering company. Machined from solid 7075-T6 heat-treated aluminium alloy with teeth precision hobbed the old fashioned way. Gold anodized and laser engraved with thread cut post-anodizing for a perfect fit. Very lightweight and very round.
Wide 7.5mm base will give a 42mm chainline on most track hubs dependant on specific hub specification - much more on this in the FAQ.
Available in 1/8" and 3/32" widths and 15, 16, 17, 18, 19 teeth. Gold anodized. And we now have a limited number of options available in blue, black & red. Note: 15t design does not have 'cut-out' as per photos. Please see this page for sample weights of VS components. All our track cogs in this section (VeloSolo or Andel, Shimano, Dicta, Token etc) have the standard ISO threading of 1.375" x 24 tpi.
A different option to run alongside our gold track cogs. Available in anodized blue, red or black with large laser etched logo and no other markings, these look superb even if we say so ourselves! Exact same technical specification as above but in a limited range of sizes - 1/8" width only and in 16t, 17, 18. Machined in the UK from solid 7075-T6 heat-treated aluminium alloy with teeth precision hobbed the old fashioned way. Very lightweight and very round.
Wide 7.5mm base will give a 42mm chainline on most track hubs dependant on specific hub specification - much more on this in the FAQ.
Available in 1/8" and 16, 17, 18 teeth.
Look familiar to a well known US singlespeed company's cogs?! These come from the exact same production facility as S*RLY but without the name.
Excellent alternative to Dura Ace. Very high quality steel cro-mo track cogs in larger range (and larger tooth count) than Shimano. Superb finish with laser etching and cut-outs on larger sizes.
Available in 1/8" and 3/32" width and 15, 16, 17, 18, 19, 21, 22 teeth.
*PLEASE NOTE* all Boost spacer kits now come with 16mm Torx stainless steel bolts NOT steel hex/allen head bolts as show in some pictures.
Update: We have spare sets of axle spacers alone - please contact us to order.
Our latest product at VeloSolo is this Boost spacer kit to fit front or rear (with rear available in both NON re-dishing or re-dishing version). Use these kits to fit a 100mm front wheel to a 110mm 'Boost' fork or a 142mm rear wheel to a 148mm 'Boost' Frame. Flexible kits allow rear wheel dishing to remain unchanged or for re-dishing if required.
Custom machined in the UK exclusively for VeloSolo from solid lengths of 6082 aluminium alloy - not cut from tube. Superb quality and precision. Anodized custom colours in black, silver, red, blue, gold & orange. Non-anodized kits also available and can be polished very easily if required.
Front kit (no re-dishing required) allows any 100mm MTB hub with 15mm thru axle to fit a 110mm 'Boost' fork. Includes 2 x 5mm wide CNC axle spacers & 1 x 5mm CNC disc brake rotor spacer together with 6 longer bolts. Unlike some kits our spacers fully support the brake disc. Rear (non re-dishing) kit allows any 142mm MTB hub with 12mm thru axle to fit a 148mm 'Boost' frame. Includes 2 x 3mm CNC axle spacers & 1 x 3mm CNC disc brake rotor spacer together with 6 longer bolts. Rear re-dishing kit also available includes additional 3mm disc brake rotor spacer (2 x 3mm in total).
NEW REAR SUPER BOOST KIT: (non re-dishing) kit allows any 148mm BOOST hub with 12mm thru axle to fit a 157mm 'Super Boost' frame. Includes 2 x 4.5mm CNC axle spacers & 1 x 4.5mm CNC disc brake rotor spacer together with 6 longer bolts.
Rear re-dishing Super Boost kit also available includes additional 4.5mm disc brake rotor spacer (2 x 4.5mm in total).
NOTE: IT IS *NOT* ADVISED TO COMBINE BOOST AND SUPER BOOST REAR KITS TO TRY AND FIT A 142mm REAR HUB TO A 157MM SUPER BOOST FRAME!
Note: for use with 6 bolt disc hubs only - NOT usable with splined rotors. All kits include top spec stainless steel Torx head bolts. Note: we do not supply 'thread locked' bolts - the customer has the choice of using thread lock or grease. If not using threadlock always assemble with grease & check bolt tightness regularly.
Very simple to fit - no disassembly of hubs or bearings required. Spacers simply slide onto thru axle when wheel is inserted into frame/fork. Rotor spacer fits behind brake rotor. This is a superb UK made kit allowing for different set-ups & is very adaptable. If you have any further queries or need specific spacers please do not hesitate to get in touch.
VERY IMPORTANT! As with any safety related bicycle parts (ie brakes, hubs, wheels, forks) this kit *must* be fitted by a competent cycle mechanic. Please check the complete installation carefully before riding to ensure everything is installed correctly with no interference issues. If in any doubt please message us and we will be happy to advise. VeloSolo cannot be held responsible for any accident/injury/damage arising from incorrect installation.
Extra sets of bolts can also be purchased - please message us if required or if you require any fitting advice.
Please see this link for Singletrack Magazine's review: Want to run non-Boost wheels in your Boost frame/fork? VeloSolo has you covered.
Please see: What is 'Boost'? for our guide to Boost.
As with our Disc and Track cogs these are CNC machined exclusively for VeloSolo by the UK's leading aftermarket motorcycle sprocket engineering company. Precision machined from heat treated high strength 4.0mm thick 7075-T6 aircraft grade aluminium alloy rather than the industry standard 3.0mm or 3.5mm. No offset so reversible without affecting chainline for longer life.
Very stiff and very strong. Teeth are hobbed the old fashioned way for superb finish and performance. Classic style with machined cut-outs (42t has drilled lightening holes). Minimal lead chamfer and full height teeth with no cut-outs or 'shift pins' give perfect engagement with the chain. Designed for singlespeed and track use, not for geared bikes. The 135mm BCD is ideal for converting a classic Campag 53/39 square taper road crank (Centaur, Veloce, Record etc) to a single ring for fixed/singlespeed use.
Variations include 130mm BCD in 1/8" or 3/32" width and 135mm and 144mm BCD in 1/8" only. The 1/8" width has nearly 50% more contact area for driving the chain than the 3/32". All BCD's available in sizes 42t, 43t, 44t, 45t, 46t, 47t, 48t, 49t. The 47t is great for multiple skid patches.
All rings are anodized black. UPDATE: GOLD is now DISCONTINUED AND SOLD OUT. All with laser engraved logo. Please see this page for sample weights of VS components. Please see FAQ for chainring bolt advice and how to measure BCD etc.
All 3/32" chainrings are 8/9/10 speed compatible and can be used singly or with a 1 x 8, 1 x 9 or 1 x 10 set-up.
These are the exact same chainrings as the black and gold models above but in a silver anodized finish to replace the discontinued polished rings.
Variations include 130mm, 135mm and 144mm BCD in 1/8" with tooth sizes of 42t, 43t, 44t, 45t, 46t, 47t, 48t, 49t. In addition the 130mm BCD option is also available in 3/32" width in the same tooth sizes.
An alternative to our own VeloSolo chainrings. These are excellent quality machined rings made in Europe with full height teeth and no cut-outs or 'shift pins'. Designed for singlespeed and track use.
IMPORTANT: All chainrings are now 'plain' and and do NOT have logos (some pictures show older models with logos).
As above but now available in black finish. Machined rings made in Europe with full height teeth and no cut-outs or 'shift pins'. Designed for singlespeed and track use.
As with our road rings the VeloSolo mountain bike chainrings are precision machined from the same heat treated high strength 4.0mm thick 7075-T6 aluminium alloy for extra strength. No offset so reversible without affecting chainline for longer life.
Very stiff and very strong. Teeth are hobbed the old fashioned way for superb finish and performance. Available in tooth counts of 32t, 34t and 36t. Two new larger sizes now in stock in 38t and 42t, perfect for faster road or downhill use. Classic style with machined cut-outs on 34t, 36t and 38t. The 32t is drilled rather than 'slotted'. The 42t has circular 'telephone dial' cut-outs. Minimal lead chamfer and full height teeth with no cut-outs or 'shift pins' give perfect engagement with the chain. Designed for singlespeed mountain bike use; on or off-road.
Available in 4 bolt 104mm BCD and 1/8" or 3/32" thicknesses. Choose 1/8" with matching 1/8" chain for a superb long lasting and strong set-up for typical UK off-road conditions (the 1/8" width has nearly 50% more contact area for driving the chain than the 3/32"). Finished in anodized black or gold. New silver anodized also now available in all options. All with laser engraved logo. Please see this page for sample weights of VS components. Please see FAQ for chainring bolt advice and how to measure BCD etc.
All 3/32" chainrings are 8/9/10 speed compatible and can be used singly or with a 1 x 8, 1 x 9 or 1 x 10 set-up.
Ideal for converting a MTB to singlespeed or to replace a worn middle chainring, ideal match with a DX rear cog or 1 x 9, 1 x 10, 1 x 11 etc. Use off-road or on-road. High quality machined Dural aluminium ring made in Europe with full height teeth with no cut-away areas. Many larger sizes now available to include 32t, 34t, 36t, 38t, 40t, 42t, 44t, 50t, 46t, 48t. The standard ratio for off-road singlespeeding is 2:1 so use with a 16t (32) or 18t (36) or maybe a 14t with the 36 or 40t or larger for a faster gear when mainly on-road.
All anodized silver, additionally many now available in black too. BCD is 104mm to fit most Shimano 4 bolt pattern chainsets (please measure the distance between the centre of two adjacent holes and the measurement should be 73.5mm). Compatible with all 3/32" chains.
Ideal to precisely space a cog away from the hub to dial in rear chainline. For example to increase your rear chainline from 41mm to 42mm simply add a 1mm spacer between hub and cog. Essential for dual cog set-ups and also perfect for disc brake applications or drivetrain modifications.
CNC machined in the UK for VeloSolo with ISO 6 bolt drilling. Available in 1mm, 2mm, 3mm, 4mm. Use alone or in combination.
Anodized colours include silver, red, black, orange, gold and blue. We also have a few non-anodized left in 1mm only. These can be polished by the buyer if desired with any metal polish. Please see stock notes below for latest stock situation. Please see FAQ for set-up advice.
CNC machined kit in five different widths - includes 1 of 7.5mm, 1 of 6.5mm, 1 of 5.5mm, 2 of 4.5mm and 2 of 2.5mm but anodized in custom colours with largest spacer laser etched.
Choose from red, gold, blue, green, black, silver, 'metallic' orange or special edition 'Rasta' mix of red, gold and green spacers.
Perfect to match up with Chris King or Salsa parts. Two new colours 'Magnesium Bronze'** and 'Titanium Blue/Grey'. New Retro Purple (see listing below to order). Please note: cogs, Token lockrings etc not included. Limited number of mixed colour 'random' sets also available.
Add a Token CNC 12t lockring and Andel SS cog for a complete top-spec singlespeed conversion kit ready to fit to any Shimano pattern cassette hub.
Note: kit is designed for virtually all 7/8/9/10/11 speed hubs and will fit over 99% of hubs. IMPORTANT: newer 11 speed (Hope Pro 4 etc) hubs (and rarely some 10 speed road hubs) have a wider freehub for the wider 11 speed cassette and an additional 2.5mm spacer may be required *IF* using a narrow 2mm single cog (this spacer often comes with the hub itself). We can supply this at minimal extra cost (contact us for details or request at time of order). If using a wider 4mm single cog (Andel, Surly etc) this will not be needed. Our kit is NOT compatible with certain DURA ACE hubs (7800 etc).
We have sold many thousands of these over the years and they have proved superbly reliable and fantastic value. Removal tool available from tool section of shop or below.
As Shimano continue to increase both their trade and retail prices we offer a more economical alternative to the freewheel above. Excellent quality model from Dicta, available in 16, 17 or 18 teeth and specific models for 3/32" or 1/8" chains. Chrome finish. Also perfect for use with modern threaded singlespeed hubs for road, off-road or BMX. Not suitable for splined cassette hubs.

Very popular bottom BB. Sealed cartridge with steel cups and excellent bearings, highly recommended bottom bracket. Many lengths (103/107/110/113/115/118/122/127) to fit any JIS chainset. See FAQ for advice on the different BB tapers.
Suitable for English threaded 68mm BB shell. Intall with a Shimano pattern splined BB tool (tool section 26BB-2A).
Converts a Shimano M756 front disc hub for use on the rear of a track/road bike. Track nuts and spacers also required. Also ideal replacement for standard 10mm x 1mm fine threaded rear road or mountain bike axle or to change from a QR to solid bolted axle.
Custom machined in the UK from EN19 high strength chro-moly steel. Bright silver passivated. Length specified slightly longer than normal to allow for track nuts with integrated washers. Choose 170mm for road/track (up to 126mm spacing) and 180mm for MTB (and road 130mm). Both M10 x 1mm fine threading. Please see FAQ for set-up advice.

CNC custom machined in the UK from solid 6082 aluminium alloy; not cut from tube. Superb quality. Precision milled to allow perfect fitting of original Shimano bearing seals giving a 'factory' finished look. Please see FAQ for set-up advice.
If you are converting a geared bike to singlespeed and you do not have a 12t lockring available from an old cassette or floating about in your spares box then this is what you need.
Similar to Shimano lockrings but machined from heat treated high strength 6061-T6 aluminium.alloy. Weight approx 7g. Anodized and laser etched. Superb finishing touch to a singlespeed (or geared) build. Looks great with VeloSolo singlespeed spacer kits.
Available in 12t blue - all other options unavailable. Choose 12t ring for singlespeed conversions with our spacers or when using a 12t small cog cassette on geared bikes. Choose 11t ring for use with an 11t cassette on a geared bike (11t lockring is NOT suitable for singlespeed spacers).
Note: Token have slightly changed the engraving and style of these - please see first two pictures after clicking on link. At present we have a mix of both styles depending on option selected.
Exact same CNC lockrings as above but now available to fit Campagnolo road bike cassettes. Again, choice of two sizes for cassettes with either an 11t or 12t smallest cog. Please see note for stock availability.
Note: we often get asked if our SS spacers are compatible with Campag hubs - they are not designed for Campag but most riders have used them successfully. Unlike Shimano, Campag have changed freehub OD dimensions over the years, the ID of our spacers is 35mm so please measure your hub with a vernier guage if unsure.
Photos show Shimano type mainly in use as a singlespeed lockring - Campag identical in looks except for engraving. These lockrings are of course originally intended for use with a regular geared bike cassette.
As with Andel and Surly cogs so it is with Zenith and Dia Compe - this is the exact same stem Zenith manufacture for Dia Compe but unbranded and logo free. Our most popular stem. Not having a GC logo makes it around £15 less and superb value. These are new to VeloSolo and fill the gap nicely between the Kalloy and Nitto stems. Quill height is 130mm with max extension of 62mm.
Styling is very similar to the classic Cinelli 1A or Nitto Technomic. Manufacture is equally good being forged, with high quality machining and a very attractive polished or black anodized finish. There is a large range of options - clamps in 25.4mm or 26.0mm, lengths in 80mm or 100mm and finish in polished or black. New length of 60mm now in stock. Quill is 22.2mm (standard 1") for threaded steerer. Angle is 73 deg. Highly recommended. Please see FAQ for handlebar and stem info

A longer quill (180mm with max extension of 113mm) is now available in two options only; 25.4mm x 80mm black and 26.0 x 80mm polished. Please email to request these options or use 'send a message to seller' when checking out.
