29er Single Speed Gearing
Some consider Sheldon Brown’s gear calculator as the one and only, there are others, some are very good. However, I’ll stick with the legend! If you need to determine what your gearing should be on your SS, use Sheldon Brown’s Gear Calculator.Eccentric Bottom Bracket (EBB)
An Eccentric Bottom Bracket (EBB) uses an oversized bottom bracket shell that houses a cylinder or "can" with an off-center bottom bracket mounting position. A traditional bottom bracket is then used and the EBB is rotated to bring the chain to the current tension. On major downfall of the EBB is they usually creak.29er Single Speed Frames
Selecting a 29er Single Speed frame is not as simple as you would think. There are a number of choices. You can select a frame that can be geared and single speed. The Surly Karate Monkey is a prime example with Track Fork Ends. Others like Niner Bikes One9 have vertical dropouts like a traditional bike but no derailleur hanger attachment which make it Single Speed only.- Niner Bikes One 9
