Hi
After 1500 miles the bottom bracket on my Giant Escape Zero 2009 has developed some play and needs replacing. Does anyone know the size I should get, bb frame width is 68mm and I think the shaft is approx 115mm. I have just ordered the crank puller so that I can measure properly but was hoping to order the BB at the same time.
Regards
Mark
