Fixed dual cassette cog.

Having two cogs on the back means you have more options for gear changes when the conditions demand it. Say you want to ride your off-road fixie from your house to the trailhead, but your gear combo is either too high for the dirt or too low for the road. With a 17/19t Dingle on the back, pick two chainrings that are 2 teeth apart, like a 44t and a 42t. When you change from the outer (44:17t) gear combo to the inner (42:19t), you'll have a much better off-road gear and your wheel position will not change. This maintains effective chainstay length so you won't have to worry about having too much or too little chain length to accommodate the gear change. Made from machined, heattreated and chrome plated SCM415 CroMoly steel. Available in 3/32" (narrow chain) tooth width 17/19t, 17/20t or 17/21t combinations. We recommend using 9-speed chains only. You can thread it onto any standard ISO threaded (1.375x24tpi) fixed gear hub and it takes up the same 7.4mm threads as a standard fixie cog. We recommend using a wider lockring (like our improved track lockring) to assure you can get a lockring tool onto it.


Cog sizes;
17/18T.
17/20T
17/21T

Note: General Fixed cog check:
for correct fixed use, the fixed cog should NEVER move on the hub when pedal force is applied in both directions.
i.e. if the cog moves, then something is wrong.
Continued use with a fixed cog that moves will result in damage to the hub.

At Triton Cycles we aim to provide a returns service that is simple and hassle-free.

Should you need to return anything to us, it is very important that you telephone us first to advise us of your intention and the reason why you wish to return the goods. If you're not completely satisfied with an item you may return it within 14 days of purchase, and as long as the item isn't fitted or used we're happy to receive it back for a refund or exchange. Return shipping costs in this instance are non-refundable.

If the item is being returned as a result of our error i.e. damaged, defective, wrong item sent etc, we will refund Royal Mail First Class or Standard Parcel postage costs. If this is the case please include a copy of your purchase receipt when you return the goods for inspection. Please DO NOT sign for goods if you think that they are damaged, or the packaging has been tampered with. Instead, refuse to accept the delivery and contact us immediately(within 3 working days) so that we can take the matter up with our courier. Replacements will be sent to you as soon as possible. Signing for goods later found to be unacceptably damaged in transit complicates negotiations with the courier in dealing with your complaint.

Please DO NOT discard any original packaging until you are fully satisfied with your purchase. Should you need to return a bicycle, couriers will not transport a machine not in the original or suitable packaging.
