  • possibly the worse post-ride film ever..
    BONJOUR FROM THE FIREFLIES VILLA on Vimeo

  • hope its all right to dig this back up, my bottom bracket is being a asshole to me again and could do with some help so i can save the frame...again

  • @ [SIZE=5]Nowhere fast[/SIZE] where u at ? Im Gorton. Ive got a Shimano BB tool n a old BB tool

  • @ nowhere fast where u at ? Im Gorton. Ive got a Shimano BB tool n a old BB tool

  • ill explain the problem first, i have the tools i need, i took the none drive side crank off, i took the lockring off, then like before when i put it in i used a pin tool to try tighten it, but now it started to wobble and now i cant undo or tighten it with the pintool to stop the wobble, at all! wont budge 1mm

    so if i cant get it out it will probably get worse and eventually be un-ridable

    tried gt-85, similar things, nothing works

    so i hoped maybe some one knew how to sort it on here

  • Any idea on the BB model cat# Sounds like a cheap BB ?

  • well its from a Guerciotti road bike conversion and it has Italian threads, that's all i know

  • GT85 is no good as a penetrant. If you can get hold of some Plus Gas and soak the BB shell in that for 24 hours or so.

  • something i could get in a bike shop?

  • It depends - a decent hardware store would be my first choice.

  • Got a picture when i took it apart, maybe it helps...

    i was replacing parts with slightly better ones to by the way

  • Threads make no difference really, can you get a pic of it ?

  • Sounds like a decent frame/BB. Italian threads are notorious for undoing themselves. WOW RONNIE IT'S DIFFO ! HOW YA DOING KID ? seen ya new Look bike on here. Yes I'm jealous.

  • shame it just hasn't come loose, ill try more Thursday

    it only really wobbles a tiny bit, you have to consintrate to feel it, but that's how it starts....

  • See timetable details here

  • I'm in!!

  • i saw this the otherday was gonna see if anyone knew anyhitng

  • Looks Great!

  • THREAD DREDGE

    does anyone have any experience stretching frames to accommodate wider hubs? Say, stretching the rear drop out spacing from 120mm to 130mm. Is this too much of a stretch? Can there be too much of a stretch?

  • Thanks rhb. I feel like I have read that before but I was probably too afraid to have a go at it. Second time round it doesn't seem too daunting so I might try it out if it comes to it. Good to have some confirmation that the stretch from 120 to 130 is feasible.

  • Will the LBS have jockey wheel/pulley bolts? Like this:

  • I dont think you'll have any problems assuming is skinny steel. 5mm each side in let's say 500mm is 1%
