First sealed bottombracket

[Ed no-more-lemons]

Had enough of yesteryears cup and cone setups, so would be grateful for sealed unit suggestions.
Looking for something to fit a JIS square taper on a standard british shell and approximatelu 120mm in length.
I am thinking about some of the sturdier Shimano jobs and welcome everyones opinions.
Thank you

Shimano UN54/55 with the alloy locking cup. Only about £15. Just get 68/73mm BB shell and the same axel width as you have now of 120mm.

Simple as that. I switched as soon as they came out, about 20 years ago !!!!

Make sure it has the alloy cup

Looks like a choice between UN26 and UN55!

Thanks Fossyant, looking forward to not being up to my eyes in grease.

As above you cant go wrong with the shimano ones, both plastic an alloy lockrings are alright but if you do go plastic be careful installing it

....Halfords are good for BB's, currently doing UN26 for £6.47 (cheaper still if you take the 3 for 2 offer). Have also used their own VP brand BB's - little dearer, but with metal cups both sides. Halfords do get a lot of flack, but found them unbeatable on price for certain parts.

Also worth noting, if it's an old Raleigh, you're stuffed! They use 26TPI instead of the standard 24TPI, and French and Italian frames are also peculiar in the BB area I believe............

You will have to for a 118 or 122... check the BB shaft size.... http://www.chainreactioncycles.com/shimano-un55-square-taper-bottom-bracket/rp-prod71369

What model to you recommend , my last 2 have started clicking from day one ,work fine till I stand up and then clickety click .

Any Hollowtech compatible BB will do, as long as you match it with a Shimano axle. Which one you choose from the many aftermarket models depends on the depth of your pockets. Most important in determining their lifespan is fitting and preloading them properly. If you want to change to HT you'll need to buy a new chainset, and most deals include a bottom bracket anyway.

Why would that advice suit the op? A replacement BB was sought not a full chainset... I'd imagine the Shimano UN55 is the square taper BB of choice (it's full metal rather compared to the UN26 which has a plastic ring). if you need a BB tool, Halfords sell one for £9; it's not so cheap as is but is included in the 3 for 2 offer.

UN55 118mm on its way. Had enough of the BB creaking or maybe its a dinosour's knee.

Superstar components BB tool is £5.99, and they've got a sale on tools.
