I have an old steel MTB and want to replace its 11year old bottom bracket. Should it be easy to remove given how long its been in the frame, and is there much risk that its removal could damage the frame threads? Grateful for any advice.

    Thewre is always a risk but give it lots of WD40 fro couple of nights beforehand and turn carefully. At the end of the day if you knackerit, its only an 11 years old steel MTB. You could by another cheaper tan a new bottom bracket.

    should it be easy?

    if it was one of my bikes yes it would as it would have been well put together.

    Lets say that your bike has been put together poorly, you will need to get it soaked in a good release agent and some good tools and it should not be too hard to sort.. Best let your LBS do it.

    as said by nicklouse plenty of wd40 release agent if that does not work try heating the frame up with a blow torch or plenty of boiling water to heat up the frame. if that don't shift it weld a 16mm nut on the side that does'nt shift and turn. :wink:
    p.s be careful with any blowtorch especially on the paint, it does'nt normally burn it but can cause it to flake off.
