The crank bearing gave out at about 4000 miles, so I guess that is OK. But the derailler that came with the bike started failing on the GAP and C&O trail ride with about 2000 miles on it. The bike shop told me that another supplier had better kit and replaced it with non OEM, 2000 mile now it still works. Also I have 700c and 650B wheel set and am having major spoke issues, they started at about 1000 miles for each wheel set (it sucks to have failure on the trail), my mass is 200 lbs, and I also have packs for the bike. So their is room for improvement with the State 4130, reliability should be the highest priority, if we wanted speed we would buy another manufactures bike.

I got a state 4130 all road about this time last year and I have put about 2700 miles on the bike. The bike to begin with has been an amazing purchase based on the limited amount of maintenance I have had to do. Any of the parts I replaced I simply bought directly from state, this bottom bracket being one of them. It was easy to replace and brought back the smooth like new feel to my cranks.

It works great. Cheap and great=Happy cyclist :)

Looks good, works well, easy to install! Very satisfied
