Easiest fork in the world to service yourself to be fair!
Just serviced my 2nd hand Rebas the other day, after printing out the guide off the Rockshox website. It couldn't have been any easier to be fair! So so so simple to work on, minimum of tools needed, and the whole thing takes barely any time at all.
I carried out a full service on mine in less than 30 minutes, and all that was needed was…
5mm allen key
10mm socket
24mm socket
15wt oil
5wt oil
Fair enough TFTuned is the place to go to if you're going to spend your cash, but based on the fact that the Reba's are so simple to do yourself, and it's pretty much nigh on impossible to cock them up, why not give it a go!
Incidentally, if you're anywhere near Worcester, by all means pop em round and I'd be glad to sort em out for you for the price of a pie and a pint! 😉
