Re:
Slightly more sensible English translation would be something like:
MARIN F.R.S Prototype
The rear section on the commercial version is a Manitou but the rear section on this is a customised ROCKSHOX MAG.
Some parts of the internals are different than the MAG 20/21 I have, but it seems like you could use the seals etc. from those.
Currently the left oil seal and the right air valve are no use.
If you have the repair kit etc. for MAG 20/21 I think you would be able to fix these problems.
There is no serial number on the frame as it was used for the MARIN race team. The front triangle is aluminium. I think the rear swing arm is the same as the normal F.R.S
It looks like it has been raced, so there are lots of marks but I can't see any cracks.
Sold as-is, no returns.
I can only send it on weekends, I plan to use Yamato to deliver.
