A few weeks ago the seals on my 2004 S-Works Enduro brain began leaking. The following week it died completely. The same thing happened three years ago. I don't know how it is in other countries, but over here in Japan it was quite an expensive repair/service and it took weeks....
Even if they still service them (I don't think they will now) I decided to get rid of the brain and buy a new shock as a service costs the same as a new shock!!! After a lot of searching and a few phone calls I decided to go for a 2012 Fox RP23 from a well known parts supplier in Ireland.
I found a lot of information on different sites but its all a little confusing. So for anyone still using an old Enduro and are unsure on what to get here is what I did -
Fox RP23 - 200mm X 50mm
Velocity/Compression - Medium
Rebound - Medium
Boost Valve - 225
Low volume air can
I weigh just over 90kg so I was told to go for a shock that had Medium factory tunes for both Velocity and Rebound. I didn't know what tuning the shock would come with so I was expecting to have it serviced at some point if the factory tuning was wrong. But as you can see I got lucky!!!
The stroke on the shock is slightly longer than the stock float but as it has the flip-flop linkage I just put it in the slack (69.5 degree) setting and the geometry is normal.
Fitting was quite easy, but it will only fit this way which makes adjusting difficult. But once its set I don't think I'll need to touch it again other than adding air.
I've got about 220psi in it and the sag is about right. At the moment the pro-pedal is zero which is fully open. Rebound is 4 clicks clockwise.
I went out for a short ride last night and climbed with the leaver in the firm (3) position and it felt great with very little bounce and plenty of grip. On the decents it was a little harsh so when I got back I added a few more clicks on the rebound. I went out again today and it was spot on. It glides over everything now and I noticed I'm taking a lot more speed into everything. Climbing does feel a lot quicker, too.
Hopefully some of this info will be useful to anyone wanting to keep their Enduro going. I've got to say it has completely transformed mine!!!
