Any question answered...

any reason why I shouldn't use one of these to install a praxis adapter BB?

Assume you are refering to part number 4

Stops the crank from wandering off the arm if you don't tighten the bolts down enough, and prevents you from tightening the bolts too much.

No, you don't need it.

Because it won't work?

Well, it might work for PF30 where the cups sit outboard of the bb shell, but BB30 bearings usually don't sit flush and are slightly recessed. That tool will foul on the BB shell before the bearings are pressed against the circlips.

Sorry, I should have said it is to install a praxis adapter BB.

Looks like Klickfix

Might work OK then, assuming the threaded rod is narrow enough to go through the 24mm id bearings (looks like it is).

Klickfix are closed at the bottom aren't they?

This is probably a dumb question, but are all BB30 bearings the same, i.e. if I need to replace a set I don't need to source them from the (obscure) BB manufacturer?

Life was a lot easier when the only issue you had to worry about with a BB was whether it was British or Italian threaded.

Correct - BB30 bearings are 6806 bearings (usually 6806-2RS for 2 rubber seals)

Is there a way to tell on sight whether a flat bar brake lever is designed for V brakes or callipers?

Trying to plough through eBay listings where this info is usually missing.

dunno, but I've got a pair for road callipers that I don't really need if it's them you're after.

And I have a few pairs for v-brakes knocking around - virtually unused.

I am! Just something not flashy but functional like this

Colour not important but can't seem to find them at LFGSS bargain price (i.e. tenner or less), which is surprising. PM me if you can help.

@Aroogah it's good but it's not the one, thanks :)

Is wiggle down for everyone else?

just you.

I have a pair of those in silver that you can have for an LFGSS bargain price if @umop3pisdn doesn't sort you out :)

That is the one. Must have fallen between the floorboards in my post-cross clean up. Thanks.

No worries. Let me know if plans change.

I have loads due to a purchasing decision which upon reflection looks a little intemperate - I'll swap you a pair for my jigsaw?

Cheers Andy.

You have second dibs on the privilege of selling to me :)

Without the make and model information, not really. You can only really tell on site, where you can measure the amount of cable travel.

What is the model number?

Thanks, Neil. But it's your jigsaw, how does that constitute a fair swap?

I'm happy to part with some bearings, which would otherwise simply be a part of my Smaugesque bike-part hoard, lets leave it at that.

Solved with a little bit of LFGSS generosity.

Another fuckwit question: I was putting some (26mm) riser bars in a (26mm) quill stem earlier because I was bored, and kind of forced them in. The bars were scored in the process. Boo hoo. Then I noticed I'd put them in back-to-front and tried to take them out again, but at some point I had to pry the quill stem open with a spoon handle to get it round a (very slight) bend because it got wedged at a bizarre angle. Once I'd got it out the stem's opening was slightly wider than before, as in it was bent open about 2mm more than it had been before.

Once I had put the bars in the right way round, it closed fine using the bolt.

The stem is a steel one of these:

I know I'm an idiot, but have I done permanent damage?
