Advice on correct BB

Thorn Raven Tour Bottom Bracket

Hi. Just doing some routine maintenance on my pre-owned 2008 Raven Tour and decided to check out the bottom bracket as it looksed a bit ropey, it’s taken quite a bit to remove the BB itself not the eccentric shell. Due possibly to 3 reasons. 1 the length of time it’s actually been installed??. 2 someone in the past has tightened the retaining screws of the eccentric shell in the wrong position into the thinnest part of the shell damaging the internal threads, lastly I think the BB I’ve removed could be the wrong size as it’s a 73mm Shimano UN-54 with a over all length of 110mm..
I’m thinking it should be a 68mm but unsure of the overall length? Can you advise please.
As going to purchase a new eccentric shell and may as well get the correct size BB at the same time. Thanks
The 2008 Raven Tour uses a 68mm wide BB, its likely to simply be the amount of time it has been fitted.

Hello,I Recently Bought A Thorn Raven. The Serial Number Is . My Question Is I Dont Have A Wrench For The Eccentric Bb. Which Whrench Should I Get For This Bike?
Hi,

If the Raven you recently bought was from new or if it was from the last few years then the tool you need is SJSC part 12076. However if the bike is much older and if it has a black eccentric (like this one you have left this question on) then the tool you need is SJSC part number 11237.

Thanks.

Thanks
