Just about to order one of the "strong bushes" off BETD. It's asking for bush length and bolt size. I'm measuring these to 22mm and 6.1mm respectively. Does anyone know if that's correct?

It's the Maestro 4.1" frame. Mine's the year before they went to 5".

Cheers.

Bushes are specific to the shock, not the bike. My guess is that it's a Fox shock, yes?

Yes, it's a Fox RP2. Here's the page on the BETD site: http://www.mountainbikecomponents.co.uk/items.asp?CategoryID=92&Name=Strong+Bushes Under the "Strong bush" section, you'll see the drop-down options.

Yeah, so just choose a FOX one. Sorted. 🙂
