Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer?

Miche....SUCKS!!!?

I'm not what happened but a few days ago I noticed something wrong with my bottom bracket... it had moved over to the right about 4mm. I know that miche bb's don't come with lockrings. My question is why? What's the point? Well what happened is I finally go to the lbs and take of my bb to find that the threads on one side of my bb shell is stripped... well nearly but the threads are almost gone. Point is, I chased the threads put some of that tape stuff on a new campy bb and put it back in. It was pretty fine when I left the lbs but now the bb is creaking... not much but enough for me to hear it indoors when I get on my pedals. Should I be worried? I just got the damned frame like a month or two ago and I don't want to have to toss it already. What should I do? Or is the frame doomed because f-ing miche thinks it's awesome not to put a lock ring on things? errr one of the many reasons I hate their parts

The creak is standard bottom bracket creak, indicative of up-and-down play in your bottom bracket spindle. With cartridge bbs, you can get the creak both (a) when the bb itself is shot, and (b) if the adjustable cup isn't close enough to the cartridge. (B) can happen if either the adjustable cup or the fixed cup aren't tightened down fully. (Yes, the Miche track bb has two adjustable cups. But for this question, it's not so important.)

What you have, I believe, is (b). And the reason you can't tighten things down fully is:

You cross-threaded the Miche bottom bracket when you inserted it the first time.

This is why the threads in the bb shell are stripped; indeed, that's pretty much the only way to do it. Sorry, not Miche's fault, but your own (or whoever inserted the bottom bracket for you.)

Also, the lack of a lockring on Miche bbs is totally a red herring -- the cups will actually get tighter with the forward motion of the pedals. The bb came out some because it was never properly threaded in the first place.

I didn't install the bb. It was already installed when I bought the bike so I guess the original owner did not install the BB correctly. I bought the bike from a friend who rode it once and decided to sell it because it was too big for him... he never touched the BB either. I'm just really upset that this even happened. I installed the new one correctly... I know that much so I shouldn't really be worried now that there's a little creaking. My question is... is my frame effed because this guy was a moron? or if this BB ends up coming out because of the nearly stripped threads is there anything I can do to keep the frame working?

oh and the threads are not completely stripped... just almot completely stripped. Does this mean that I still did not tighten down the cups all the way?

4mm to the right is not at all unheard of for italian bottom brackets...*on the drive side* drive side lockrings are *ahem* very uncommon so i'm assuming that either 1.) you're referring to the lack of a fixed cup on the drive side, or 2.) the non drive side came loose (unlikely). adjustable cups need to have either some form of loctite or at the very least plumbers tape to remain in place (doubly so with italian thread). the purpose is to allow for a slightly adjustable chainline and, if installed properly, can be a lifesaver. cartridge bearing bottom brackets don't have lockrings (see shimano un*). saying that "miche sucks" is really quite silly.

Not to preach or pile on, but people need to stop taking one bad experience with a product, which is generally regarded as of high quality, as evidence that the entire product line is crap.
Miche do not suck, neither do Pro Max.
Sorry.
Carry on.

I wasn't being serious about that miche sucks comment. It was more of a joke because of all of the suzue sucks... etc threads that have been coming up of late. That said I don't really agree with a lot of miche designs but I don't really think they suck.

I really like this Miche headset I have though.

there are threadless bottom brackets that lock in and use absolutly no threads what so ever. they work great from what i hear. i know stronglight makes one they are made so that when this kinda thing happens you don't have to toss a frame. a lot of good frames can be saved this way. http://www.zefal.com/stronglight/pag...keyProd=jp1000

also new bb don't use lockrings, they don't need them.

i don't know what the comptability of campy bb with miche cranks is, but i think some have diffrent taper size. did you use a 70mm wide bottom bracket? also if you used one of the alloy taper campy bb and it doesn't fit perfect with your cranks it might cause disaster for your cranks.

... your frame is likely fine, this is on the yellow bike right? It's steel, those cups are aluminum, steel wins hands down. My Miche BB used to come loose for awhile, I would notice it at the first hint of play because I'm neurotic/hypersenitive to that kind of stuff and picked up on it immediatly; no damage done. I took it all apart, cleaned the whole shell out with alcohol, took a shot of makers, cleaned the BB threads and with a bit of blue loctite wound it all back up to spec'd torque. I have never had a problem since and I have taken it out 3-4 times since to clean and repeat. I'm coming up I think this week again lets ride if your around. laturdood.

I've actually been using campy cranks on the miche bb, but just until I could afford a record bb... well didn't get the record, I'll tell you that much but it's campy on campy so i'm pretty sure i'm alright.

With Italian threading the Miche bottom brackets can force themselves loose. Happened to me, thought i needed to adjust my chain tension only to find that my bb was shifting. Blue loctite solved everything.

Oh and Miche stuff really does suck. It will ruin your frame, make all your oter components jump off, and the girls won't sleep with you unless you have NJS certified Campy. Because I'm such a great guy, send me all your Miche garbage, and I'll dispose of it properly so no will get hurt.
