I have BB5s on the commuter and BB7s on the MTBs. I prefer the BB7s – IMO they have better stopping power and require less tweaking to keep in top order. Regardless both are fine when set up correctly.
If you do need instructions on how to set up BB7s get them here
Of course I have never used these instructions so can’t comment on whether they are any good 😉
Remember, only once all else has failed should you then refer to any instructions.
Is that before or after taking the part that is in bits to yous LBS for some piss taking?
Without instructions, my mate once took a SRAM shifter apart as it wasn’t working well. He then couldn’t put the thing back together again. So he proceeded to take the other (working perfectly) shifter apart to see how it fitted together. Great plan! Id have loved to be in the bike shop when he turned up to explain why he wanted them to re-build his shifters 😆
