Is there any phrase in mountain biking that’s more overused than “longer and slacker?” Every manufacturer (Ibis included) is guilty of it. It makes bikes descend better but the question is, how far can it be pushed? We felt we were at the limits of that trend until we began experimenting with seat tube angles and fork offset.
By making the seat tube angle a steep 76°, we’ve put more weight over the front tire. This keeps the front end from wandering or washing out. Moving the seat tube forward also required pushing the front end forward to keep the top tube numbers static, resulting in the longer reach.
In addition to the steep seat tube, the Ripmo also uses a fork offset that is shorter than traditionally used. That makes a 65.9° head angle feel like 64.5° without increasing the wheelbase. You get the stability of a slack head angle without giving up your ability to go around tighter corners.
The Ripmo geometry enables a new level of confidence and speed, bringing the stability of the EWS Team Championship winning HD4 to 29” wheels.
One look and you’ll know: this is an Ibis. The Ripmo features Ibis’ typical flowing lines and the DW-Link rear triangle. The suspension offers 145 mm of travel, controlled by a FOX DPX2 Performance shock. If you prefer, you can upgrade the shock for a FLOAT X2. Ibis gives its customers a lot of freedom in the choice of components on the bike, offering various combinations of builds. Admittedly, at a price of € 8,498 the bike we reviewed is very expensive, but regarding the componentry, you’ll get your money’s worth. It features a SRAM X01 drivetrain and a 160 mm FOX 36 Factory fork (currently without GRIP2). The Ibis 942 carbon rims with a 35 mm inner width are an absolute highlight. They come fitted with a set of MAXXIS WT tyres consisting of a Minion DHF 2.5? and an Aggressor 2.5?. Again, a point of criticism is the small 180 mm rotors for the Shimano XT two-piston brake. They work much better with the XT than the SRAM Guide on long descents, but we would still have preferred bigger rotors for more power.
