White Bros makes 100mm and 130mm travel forks in the BW series. They also just introduced a completely new design (called IMV) that I think is just coming available now. Check the 29er board for many posts on IMV.dogalope said:
I own two 29ers, one with a 80mm Reba and one with a Maverick DUC32. The Maverick is MUCH better, IMO. Much plusher/smoother. Feels a lot like the Fox forks I have ridden in the past.
The big problem with the Mav is cost. You can find Rebas in the $300-350 range, so you are probably talking about half-price or better compared to the DUC.
The Reba is not a bad fork, just not nearly as smooth as the Mav.
Marzhocchi also makes a 29er Marathon. I have no personal experience with this one - you might want to check the 29er board for info.
