I like whats going on at the front end.

The difference between models is basically the usual difference in 12.1 and 12.2.
Which amounts to £70 for a diff, a complete set of spacers for axle and some other bits n bobs.
A diff is £40
A complete set of (9 pairs) of axle height spacers, which are moulded plastic, will cost you £22.
I know they have to pay for the tooling and all sorts of other costs but its none the less a surprise.
(i just looked at the first site that was selling spares btw)
I think that manufactures are going to have to try very hard to out run the seemingly archaic Mardave design.
Bling does not cut it on the track. Zen had better be using science and numbers.
Given the choice between a Schumacher and a Zen. I would take a Zen.
