- Super tough hardened Cro-Moly sprocket from Halo, much more wear resistant than similar Stainless Steel sprockets.
- Available in 4 ED coated coloured finishes! (Please note that this is a surface coating and will wear off under prolonged contact with the chain.)
- Full CNC Machined construction, with shot blasting afterwards to increase surface hardness and durability.
- 7.6mm wide base.
- Only compatible with 1/8" or 3/16" chains, such as the KMC K710, Z510 HX, Collapse or the Gusset Tank Chain.
- Industry standard 1.37" x 24tpi thread fits most fixed screw on rear hubs.
- Available in 15, 16 and 18 teeth sizes.
- Weights: 15T - 54,2g. 16T - 64.3g. 18T - 71.5g.
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.
Not recommended for use on crank arms.

Hi Connell - It would do, but as it's a 1/8" sprocket you'd then also have to use an 1/8" chain as well (such as the Trialtech K710 or KMC Z510HX). If you use any of the other screw-on sprockets we have then they'll allow you to use any chain you'd like. Thanks, Mark
