Taller gearing

Recommended Posts

Hi all. Need some advice please. I've been riding a 3x10 setup with a 42t big chainring. I found that I run out of gears on some fast downhills. New bike has XT 2x10 with 38t big chainring so the situation will be slightly worse. What is the easiest and better (cost-wise) option of increasing the gearing ? Thanks

I have 44 lying about somewhere if interested. Does not fit due to chainstay too wide .

Thanks for the offer. Is this a complete crank? If not, is it a ring that needs to bolted to a spider? ...learning my way around bikes.

get a road bike :w00t:

 

I'm on the big side. Just sold my road bike as I feel more confident with larger volume tyres, plus the added comfort

Fit a road groupset or find a proper hill where you do more than spin. I ride a 40 upfront with no issues.

I was told that I could simply fit a road crank, with some mods and this should sort things out. Do you agree?

Surely though if you are on the big side then you are going to struggle going uphill with the taller ratios?

You wont have that tiny 3rd ring to fall back on.

On the 3x10 setup, I'm not actually using the granny gear, but that's a 24,32,42 arrangement. Something like a 30,39,50 would work for me I think.

 Learn to spin, that will help you going up and down hills. Get out on a flat road and spin for 5km at 120 rev./min

to go from 42 to 50 is huge, i would not do that. i can reach around 40km/h on downhill (dirt roads) not sure if i would attempt that speed any other place.

 

what speed do u wanna reach and what speed are you getting to now?

I regularly get close to 50kays at which point I'm out of gears. Sorry I should have mentioned originally that I'm experiencing this on tar, not trail
