Who here uses a road cassette on an MTB?

In my thread about "losing bike weight", it made me think and consider switching the cassette to road gearing. I rarely even use the rear granny gears, so why not have a better shifting ratio + further weight reduction.

They're just cassettes. Use whatever cogsets work for you. For my mountain bikes I like 12-34s generally paired with 22/32/44 rings. My road bike 12-27 (39/53 up front) works well.

You'd still have about 26 extra gears.

Shorter gear ratio's also = better shifting

Yes.

But you knew that already.

Toronto has modest hills, I ride the don trails on a 34-25 low gear, most of the time
