Big Crisis

hi yesterday i tried to pedal hop then something rounded off at first i thought it was my bb or chainring but i just found out today that its my profile. the problem is, is that its not engaging when i put pressure on. has this happened to anyone else? and does anyone know whats happened and if i can fix it?... or could i send it somewhere to get it fixed so i don't have to splash out on a new one?

cheers for any help

Check the ratchet ring. Are the ridges OK on it? Can you spin it with your finger?

EDIT: You are sure it's not your fixed sprocket spinning on the crank 'cos you've stripped the thread? What cranks are you running?

How new is it? Will and myself have found that new profiles have about a month of bedding in, after which all the loose bits of pawls/springs/teeth etc end up inside the mechanism causing it the skip like a maniac. It sounds like you've had a worse experiance than I did, but not unlikely that this is the same case

Heres a quick check for it

Take the wheel off and the axle fun bolts for drive side. The driver should just pull straight out but may require some tools or a lot of force. If it falls out though, don't worry

With the driver (the bit with the cog on and about 4 bearing races inside) out, you should be able to see some small pieces of metal on the other part of the hub (usually, it gets stuck on the axle bearing rubber seal but check everywhere else too) If you can't see any bits, read a bit lower down, but if you can, get a small brush like a toothbrush and gently clean all the bits onto a rag for binning. Reassemble the hub and it should work fine (Y)

If you can't see any bits

Leave the hub and go back to the driver. You should see the 4 pawls sticking out in a nice pattern. First check the springiness of the pawls, do they even go in? or is there some dirt preventing it? Clean if so

If they go in and don't return (or indeed were never sticking out in the first place, see if you can see what is happening with the spring steel. Does it need a slight bending out to keep the pawls spring loaded? Are some of the springs missing. Whichever the case, you may need to order some new springs, which some kind TF member will locate a cheap place for buying them separately, im sure :)

Other than that I can't think of anything, sorry :( Hope this helps though (Y)

Sounds like the driver's not the issue here, Partz?

Just check that ratchet.

no its deffinatly not the chain ring as when i do try to pedal the chainring stays with the monty cranks and the bb is the same.

whats the ratchet ring?

sounds like the ratchet rings detatched itself to me, are there any bangs or cracks or just a wooshing sound of death?

lol its sounds like its the bb .. it like goes glunk and the silent as it tavels around but i think it could b the bb as that would mean the profile would engage

its pretty old about 5 month at least ive checked the pawls and they seem to be fine but i will go looking for the metal thing :blink:lol and see what happens could anyonje tell me what the rachet is? looks like? and were abouts it the hub its located?

cheers for the help

Well, I wasn't disputing that fact, I was just answering this question "could anyonje tell me what the rachet is? looks like? and were abouts it the hub its located?" which was asked at the end of the previous post.

They aren't part of the hub though. By that I mean it's not 1-piece with the hub, in that it's just pressed in (or screwed in... it can be replaced at any rate). Therefore, it's possible to bugger it up in the way he has...

the ratchet ring threads have stripped, same thing happened to mine.

i sent it to profile europe and they replaced everything that was haggard for 1/2 its retail price and didnt charge for labour, which is nice! even though they lost the hub twice whilst it was there :S
