 You don't need to be an 'investor' to invest in Singletrack: 6 days left: 95% of target - Find out more
I've read some posts mentioning running different ratios when single speeding - Anyone any advice running an Alfine 29er?
I think I'm on 18 / 33. Can check next week as that bike is in Aberdeen and I'm not.
I asked the same question recently and went for 34chainring with 23sprocket for my Alfine 29er,it seems to be perfect so far.
Tried a few combos and settled on 32-21.
33-18 here
I went for 32:18 as it meant that I could easily swap it with a singlespeed wheel which also had an 18T sprocket. It feels like it gives a similar range to a 'normal' middle ring/cassette combination.
When I had one, I ran 34/22 on it. Basically, I worked out what I thought would be ideal on a 26" wheel bike (34/20 for me) and just increased the rear cog size by 10% to take into account for the larger wheel.
