Question

What is correct BB for 2007 Giant SCR2 triple chain-ring?

I have removed the old BB, and it is an RPM BB-7420 with BC 1.37x24T lettering. There is a "68" stamp on the main body and "B-113" on the spindle, which I guess makes it a 68x113. I believe that the Shimano UN54 68x113 is the compatible BB - is that correct?

Sounds bang on. If you're in any doubt just measure the body and the spindle.

Question

Do you sell shimano un72 bb

I am trying to upgrade my old raleigh grand prix (1977) to run on a triple ring sugino AT crankset and need a bottom bracket set that will clear the chainstay. I think that the shimano un &@ (68x127.5+2mmspacer) may be my best overall option to solve the problem. I have read on a couple bike forums that you sell these old shimano sealed BBs.

Unfortunately I can't find the specifications for the 1996 Kona King. I recommend contacting Kona directly who should be able to help you with the size you need.

If your chainset uses a ISIS connection you should be fine with the Signature bottom bracket. I think that the Trance X3 2008 uses a Powerdrive connection though which we do not stock a replacement for, be sure which one you need before purchasing.

We don't stock a Square Tapered bottom bracket in 116mm but we do stock the UN54 in 115mm and 118mm. The 115mm should be fine, I will link it below for you.

If you have a bottom bracket with a axle that is attached to the chainset, you will need hollowtech II external bottom bracket cups as linked below. Otherwise you will likely need a square taper bottom bracket such as the UN54 as linked below. There are other mounting methods, you may need to e-mail a picture to us at sales@wiggle.co.uk so we can identify it for you.
