I have a Jekyll with Deemax wheels in the shed; the silver and green Deemaxs work a load better, but I’d do a swap and live with the yellow rims for the carbon frame.
Not had any problems with the rear shock and the concept works brilliantly. It’s surprising how quick the bike climbs considering how well it descends. The Fox 32 150mm forks look a bit daft, but I have some Totem 2-Steps that sort that out.
The general opinion seems to be quite negative, but the two other riders I know that own and ride them both rave about them too.
I’d hypothesise that the reason sales are low and you don’t see many about is that lots of people think the shock will blow up, so write them off without riding them, see above posts for details.
That said, all the owners I know bought them cheap when Paul’s Cycles were banging them out. I wouldn’t have paid the £3.3k that mine retailed at.
