- Trialtech splined sprockets are CNC machined from super tough hardened Cro-Moly to offer a high level of quality and durability.
- A shot blasted surface finish after machining increases the surface hardness and improves durability.
- Wide 4.5mm base gives a greater contact area between hub and sprocket, reducing interface pressure and helping prevent ‘dig-in’ problems associated with narrow based sprockets.
- ‘Beefy’ tapered design gives maximum strength, while CNC machined slots (17 and 18T models only) help keep the weight down.
- Compatible with all 1/8" and 3/32" chains.
- Industry standard Shimano HG spline pattern.
- Can also be run in a cassette for your main drive gear. The 4.3mm wide base is the same spacing as an 9 speed Shimano cassette - meaning one of these little beasties will fit in perfectly!
- Stylish laser etched logos show great attention to detail.
- Available in 14, 15, 16, 17 and 18T.
- Weight: 14T - 29.5g. 15T - 37.6g. 16T - 44.5g. 17T - 43.7g. 18T - 48.9g.

Additional Information

Please note that we recommend double wheel tensioners for 15T and smaller rear sprockets. This is to ensure a healthy amount of chain wrap and help to eliminate the chance of the chain skipping.

Hi Mathew - Unfortunately this sprocket only fits screw-on cranks/hubs, so unfortunately it won't work with your BMX setup. Thanks, Mark


Will this fit an old echo 6 speed fixed hub?

Hi Chris - If you have a 6-speed Echo hub then I believe the Trialtech sprockets should fit - it's just their single speed hubs that use their own spline design. Thanks, Mark

Will this cog fit on a Chris King S/S Trials Hub?

Hi Sam - I've used the Trialtech sprocket on my own King hub before and it worked fine. I don't think you'll have any problems! Thanks, Mark


Would this be suitable for an American Bottom Bracket and if not, what would I need to fit it?

Posted by Julie on 20/10/2013

Reply from TartyBikes on 21/10/2013

Hi Julie - this would not fit a frame that requires an American Bottom Bracket. This is a Euro type BB. You would need to purchase a BB that is specifically designed as an American type bottom bracket, though unfortunately we do not stock any. Thanks, Flipp.

Hello, will this fit with the Hope Pro 2 Evo 40T Trials / SS rear hub, on my Ozonys Iron frame? If so, do I need to buy some kind of adaptors with the sprocket? Many thanks, your answers are very helpfull

Hi Sabrine - This sprocket would work fine with the Pro 2 Evo 40T hub. I use the exact same combination on my own bike. The only other item you would need would be a Cassette Lockring - your Hope hub should have come with a single speed spacer kit which will allow you to space the sprocket out correctly, meaning you just need the lockring to hold everything in place. Thanks, Mark
