Forks definitely need to go, as they weigh a ton and have a horrible top-out clunk.
Brakes are serviceable, so probably worth using until the pads wear out 😉
A friend bought his at the same time as I bought my geared version. I bought mine because I’d tested the top of the range,’Paragon’ which uses the same frame. Really liked the Paragon, but couldn’t get on with SRAM shifters, so bought the bottom of the range model and changed the bits I didn’t like.
We both fitted Manitou Tower Pro forks – which have an offset almost the same as the stock G2 items, but are significantly lighter.
The Tektro cable brakes were replaced by some bargain priced Shimano hydro units, and I fitted a complete SLX drivetrain that was irresistibly priced on a German website
The result is that we both have comfy mile munchers that we’re very pleased with.
Another friend borrowed to single speed to attend the recent SSUK2013 event and absolutely loved it.
Now I think about it, I know somebody else with the SS who has Manitou forks fitted.
If you can locate one, it really is a good starting point to a great SS build.
