Just to balance out the bad reviews.
I built up a 2nd hand carbon ransom about a year ago, it has the equalizer shock. I think the alu ones are a bit heavy in comparison.
I ride in varied terrain in the basque country, lots of drops,rock gardens,big mountains. Best bike I´ve ever had and it makes me want to take on 2 hour climbs just to enjoy the descents.
Never had a spot of bother with either the frame or the shock.I did read a few horror stories and as a result I picked up a spare shock just in case (cost me 35quid), although that one did need a service. It can also be replaced by a modded DHX5, saw that on a few forums.
People will write a bad review if their bike breaks, if it doesn´t then they´ll be out riding.
