While my '05 Mongoose Teocali has been a good steed, I've had the same problems that others have had with premature wear of the needle bearings in the rear bottom bracket linkage. Apparently our overseas friends have found a fabricated bushing solution. I haven't pulled the trigger yet becuase I don't want to ship my linkage overseas and be without a ride for a month, but I thought I'd make other teocali riders aware of one solution. It looks promising. Please post back if anyone tries it (including total ship/recieve time): http://www.fogma.co.uk/foggylog/archive/365.html
