stewie911 Posted August 13, 2010 Share There is a thread about this. "Going 2x9" Your gearing depends on the terain. For gauteng conditions I'm loving my 29-42 with 11-34 at the rear. Could even ride 11-32 Link to comment Share on other sites More sharing options...

Could even ride 11-32 I'll check out the thread... agree with you on terain, KZN races always have some steep climbing? also probably comes down to rides strength, and weight. a heavy weight might stuggle with a 30 and only 11-32 at the back. Hope it suits my 75kg's Link to comment Share on other sites More sharing options...

29thumbs Posted August 24, 2010 Share Why do you create problems for yourself.i feel sorry for you on a race like 2Hell and back. What you see the pro's ride is very specific to a race.some races they use 2x10 others, the standard setup. Link to comment Share on other sites More sharing options...

What you see the pro's ride is very specific to a race.some races they use 2x10 others, the standard setup.I did all of Jo'Burg 2 C on a 2x10 with a 29'er.Spioenkop and some of the climbs leading up to it was between 20 and 25 % gradient, I had no problem.Heck, I ride my singlespeed 29'er all over the place, and I am no pro.
