|The lowly bottom bracket. This one is a thread together PF replacement by Wheels Manufacturing|
That said, in all my bicycle mechanic years, I would have to say that the lowly bottom bracket gets blamed for everything. Especially noises. Those always seem to come from the bottom bracket!
Okay, before I go on let me say that I know not all noises come from the bottom bracket, and so do many of you. I speak as one who works retail. In that world, bottom brackets do get blamed for an awful lot of things that they shouldn't be blamed for. It's kind of like the proverbial saying where someone has a little bit of knowledge and then is "dangerous" with it.
Besides being blamed for all sorts of creaks and groans, some of which bottom brackets are to blame for, these components get blamed all the time for not conforming to "standards". I think what many folks get bent out of shape about is the seemingly never ending parade of different, competing bottom bracket styles. You have your Press Fit 30, Press Fit 41, Outboard Bearing cup, BB 30, fat bike, Press Fit 121, GXP, Shimano 24mm, BBright, and who knows what else. That seems absurd, but you really have no idea what absurd was concerning bottom brackets unless you go back about 30 years.
|Remember these clunkers? This was actually pitched as a "standard" everyone should use!|
Yeah....bottom bracket standards. Those were the days, right?
I also remember a time when "The Industry" was trying to standardize the bottom bracket without Shimano. There was a bottom bracket which was an alternative to Shimano's "Octalink" cartridge bottom brackets that was going to sweep the industry and everybody would be using them. It was the ISIS style bottom bracket, developed as an "open standard" so there were no patents to observe or licensing fees to pay to utilize the design. There were only going to be three spindle lengths in three bottom bracket shell sizes. Simplified bliss! We would all cheer for joy because bottom brackets had finally been standardized!
Except that one niggling detail- they sucked at actually working for very long.
Yeah....that's a problem. So then we all forgot about trying to unify the competing bottom bracket factions under one style to rule them all, and now we have all these wonderful choices.
Choices are good.......right?
