Gearing for DH race bike

Hi Lee.

I have a Demo 9 that I use for DH racing. Right now I have 34t chainring and an 11-34 cassette. I want to switch to a road cassette. Which one should I use?


Ring Cog Ratio
38 26 1.46
34 23 1.47
38 12 3.16
34 11 3.09

Hey Agustin.

Try an 11-23.

The ratios will be almost identical to a 38t with a 12-26, which is popular among downhill racers.

Compared to a 38, the 34 slightly increases friction and the stress on your chain, but it’s lighter and it improves your clearance.

Rip it up!
