    Thank you...is it possible to get a 73x122.5mm BB these days? I was thinking a UN55 was a suitable replacement but it seems to be Italien threaded (I guess that`s not right) and I can`t find one in the correct size..

    Re: Re: Hya..I think it`s a 94 or 95 model as it has TIG welding not lugged joints. I`m pretty sure I measured the actual shell correctly at 70mm...it may be closer to 73 including the tighten cup that lies flush against it on the right side. I`m not really understanding about the cup...

    No...the actual frame width is 70mm excluding the cup wall thickness that`s flush against the frame on the drive side.. The front mech is working very well...I`m waiting for a new RD to see how that is..

    Banjabbi...well the BB is 68mm and the BB shell is 70mm....in your opinion is that a problem?...the same guy who sold me the frame also sold me the BB and gave me the chainset so I assumed they`d all be ok. He did give me the wrong size front derailleur initially though..

    ok..thank you...I`ll check that now. I`m assuming if it`s the wrong size it will really mess up my gearing?

    oh..I`m not a technical person...when you say shell do you mean the part of the frame the bottom bracket goes into?...should I measure that? I was told the BB had to fit the chainset, which it should ; ) Yes there is a problem with one of the limit screws not doing anything..I have a replace...

    Re: Re: Just to clarify I had real trouble putting the BB in and tightening it at first..the left side would tighten up but then the right side cap wasn`t flush with frame. So the last ime I put it in from left to right but fully tightened up the drive side first until the cap was flush with...

    Re: Re: oh...we fitted the bottom bracket by pushing it in left to right and tightening a little...then tightening the right side until the cap was flush with the frame..then tightened the left up. Should we be pushing it in from right to left with the left cap off...tightening the drive side...

    Re: Hya..well with the BB un71 it is the right side collar that comes off...I`ve checked out other photos of it on google to make sure. I`ve followed the arrows to fit left to right so it should be in the right way hopefully ; )

    Is this right? strange bottom bracket issues..

    Hya everyone So I`m building up a Trek 950 and fitted a Shimano Deore FC MT60 crankset with a vintage XT 122.5mm bottom bracket which the same seller supplied me with as matching. I had a bit of bother getting the bottom bracket in as the threads on the frame were a bit messed up and needed...
