Quick mechanical question re cassette

Doc07 · 03-12-2016 02:22PM #1

Getting a direct drive turbo which has an 11speed cassette already on it. I've 10-speed cassette on the bike.
Will I get away with simply popping my bike and 10-speed chain on and fire away or will I need to put a 10-speed on. I know it's not advanced mechanics to swap cassettes but I'm trying to avoid (anymore!) unecessary purchases.

I would say it'd be crunchy. But to confirm - why don't you quickly try a buddy's 11 gear rear wheel on your 10 gear bike.

11 and 10 speed are not compatible. You will have to change the cassette on the turbo to a 10 speed, or buy a new 11 speed bike!

Thanks. In my simple mind I thought it might be ok somewhere in the middle of the block.
So if it has an 11-speed now, then I need to put on a 10-speed and a spacer?
Thanks
(Would love to be able to justify new 11-speed bike)

Yes. That'll do it.
10 speed cassette and spacer.

If you find a sweet spot with one gear...that should be OK in theory, but if you want to change gears it will be messy. Your levers are designed to move in 10s increments, versus 11s ones.

Spacer and 10s cassette as mentioned, is the way to go. A 10s cassette is a lot cheaper than a new bike in fairness.

10 speed chain may be too wide to run between the 11 speed cassette chainrings. As above get a 10 speed fitted on the turbo!
