2004 m50dx bottom bracket
Does anyone know the stock BB for a 2004 m50dx ?
I've spend days searching the internet with no luck.
I purchased a used 2004 M50 DX of craigslist for $125 and I love it. The only issue is once I had it tuned up at a shop I noticed a grinding sound that sounded as if the BB was going bad. I took it back to the shop and they told I must be riding "between gears".
It always makes a grinding sound on the down thrust of the right crank.
Anyway, I believe I need to replace the BB but can not determine the BB size.
Any help would be greatly appreciated.
I was going to try Raleigh customer services and see if they can help but I figured I try here first.
