$100 for a FG/SS rear wheel with ENO eccentric hub / Mavic Open Pro rim. This is perfect for anyone who wants to try fixed gear or single speed on just about any road bike. The eccentric hub allows you to adjust chain tension with vertical dropouts.

– You would have to shorten your chain
– For FG you would have to buy a cog & lockring
– For SS you would have to buy a freewheel
This is not my ad but I’m so tempted to buy this for myself (last time i did that karma bit me in the arse)
