I had one for about 6 months, main bearings (big switch link ones) wore out after 3 and cost me £60 to replace, lower eyelet bush only lasted a couple of months as well. Paint chipped off really easily. Shock wasn’t progressive enough without a volume reducer.
Good stuff- geometry was excellent, nice long TT. Looked amazing. Was easy to strip down frame and replace bearings!
After owning many multi pivot bikes I’ve now got a Heckler, 2 bearings with a lifetime warranty. Can’t tell a lot of difference with the suspension action. If you look at the amount of movement in the switch link on an SB66 its not a lot, I can’t see it really making that much difference to the way it rides compared to a single pivot. Just over complicated for the sake of it and not very compatible with mud.
