I have a Sram Red crankset.

I've been reading reviews on Sram bottom brackets, a lot of the reviews say they wear out very quickly.

Has anyone had experience with Sram BB or does anyone have suggestions for Sram compatible BB?

    dont worry about it till you need to change it. that may be years and then there are loads of options.

    I bought the bike second hand, however since I've bought it's lasted about 6 months

    Ah well! you need to change it. Excellent news, bang it out and replace like for like or get a Wheelsmfring one. Praxis are good too.

    it might seem like a daunting task but is very straightforward, there are lots of threads on here but to shortcut do a search for the parktool and Wheelsmfring videos on you tube. The wheels website has links.

    Tools

    Hammer
    BB remover (depending on how stuck in your frame it is)
    something to press the new BB in and possibly a BB tool depending on the system you use
    a pinch of grease
    20 mins on gas mark 2

    sit back and congratulate yourself for manskills :)

    Surely it depends on whether the crankset is a BB30 variant or GPX.

    If its BB30 then Vino is right.

    If its gpx then the removal method is the same as HT2 - just screw the BB out from the frame on each side.
    For replacement you could use gpx or a HT2 bb with a 24/22 gpx adaptor - Hope do one but its not cheap.

    It makes no difference what crank axle is used. What matters is whether it is press-fit or screw-in. So, BB tool as per Vino's post.

    The axle dimensions will be different, depending on the BB type.

    So what? It makes no difference to the removal / installation. It's either pressed in or screwed in. Bang it out with a drift or unscrew it; press a new one in or screw it in as required. Replace like for like.

    Sorry yes, youre right i was assuming BB30. but theres still a requirement for press and/or BB tool.

    Either way its a piss easy job

    I think we pretty much have the various BB issues nailed in here now :)

    Had GXP BBs on my mtb for years. Get a couple of years or 1k miles out of them. £20 and a few mins work makes them decent value in my eyes

    If you are only riding 500miles a year I'm surprised you find that a new BB only lasts for 2 years. Unless you are riding through fords or something?
    FFS! Harden up and grow a pair :D

    On an MTB, quite possibly...

    Get the hammer out Bobble. If youve never taken a hammer to your bike before youre going to need to add a stiff drink to the tool list :)
