Just back off hols (Dordogne, since you ask,very nice too. Report of
Course Cycliste to follow).
Anyway, whilst away I road,inter alia, my sons Specialized Rockhopper
XC rigid. I think that's the right model - a 200 quid no suspension
MTB. It has a clonking noise and feel once per pedal revolution, which
occurs regardless of pedal type, so prime suspect is the bottom
bracket.
As the bike is 6 months old, I took it back to the shop to see about a
warranty replacement. They claimed the bottom bracket is a consumable
item. I was a little gobsmacked. I pointed out its main use is to
school and back, which is no more than 2 miles, probably only 1. They
wouldn't shift, saying that was 6 months almost continuous use. I
left.
Sums done later sugget that 6 monthsx 4 weeks x 5 days per week x 4
miles perday = 480 miles. No way sould a bottom bracket last only 480
miles, even if it is made from cheese,it's not fit for purpose. Let's
be generous and say he's done a thousand miles on it. Does the panel
think a sealed bottom bracket should only last 1000 miles?
The bike is generally well maintained, kept in a draughty garage along
side a fleet of bikes which have many more miles than that on their
BBs. Theschool trip is on road.
I'll remove it later this afternoon to see the make and model.
