The Bow went through so many bottom brackets in the two years I had it, I lost count. Shimano ones seemed to last about 3 months in the winter. Eventually I tried the Gusset one with needle rollers that seized in Russia (it was completely worn out though)
After considering all the expensive options Cycle Shack offered a deal on an MSC Ceramic bottom bracket
