First and foremost.. I'm slowly trying to replace my bottom bracket.. it makes a kind of knackered-bearings sound when I move the pedals round without the chain attached. This is because I've been bad and not washed my bike after cycling out in the rain, snow and gritted/salty roads. Whoops :(
I have a Trek 1.5 2011 with a compact chain ring.
I'm having great difficulty identifying what sort of bottom bracket it has. I believe the crank is an FSA Vero, 50/34 if that helps.
Unfortunately the manufacturer does not provide any information on the bottom bracket.
How can I identify for sure what I have, what I need to get, and what tools I'll need to replace it? I really don't want to start spending lots of money on the wrong tools and the wrong parts.
Any help would be massively appreciated!
