mtb stiff crank

[pano amo]

Have what I think may be a problem with my lapierre mtb bike. Its been sat in cold garage for the last month and while giving it a warm-up yesterday and some essential oils, I noticed the crank is really stiff. It doesnt seem to hamper pedalling too much but if I back pedal or rotate it back when standing, its quite stiff and not wanting to move, theres no play in it. It was in for its first service some months back at Evans and they had the crank off to lubricate it. Any ideas what is causing this? Something I can do easily or best left to the professionals?

Thanks guys. I used to keep it in the house but the missus made me put it in the garage. Should have put her in the garage

Turn the bike upside down with the seatpost removed. My Lapierre frame gradually fills up with water over time which collects in the BB . Lapierre also fit low quality press-fit BB's so they dont last long even if treated well. Removing the crank and re-greasing may help but dont try to remove the seals as they crack easily.

What is a BB?

Should I look at getting a better BB then? If so can you recommend one not too expensive. My other £300 basic mountain bike out in the flippin shed all winter is of course working perfectly

Thanks RickIV. I saw this on another forum, maybe it was you who posted it? I emailed the company to ask them what BB tool they supply to remove it should I need to but they didnt respond. Can believe the price of press fit bottom bracket removal tools! And I'd rather not take the caveman approach to it either as some have done.

Sounds like a good idea, that pulley bar. What do you mean by getting the frame faced?

Is it just shimano and enduro that do press-fit? Are they trying to set a new standard, an alternative to regular screw-type BB's?

I think you're confusing two different things. Shimano's current bottom brackets (HT2) screw in to the frame like a normal bottom bracket. but the bearings themselves are press-fit into the bottom bracket. Some frames feature integrated bearing seats, so you press the bearings into the frame directly. eg BB30. Both are being discussed on this thread.

ah ok
