Love child of the Ripley and Mojo HD4, the new IBIS RIPMO is a stand-out bike with its big wheels, always ready for another round, whether it's a long climb or in the back of a pick-up. With a frame weight of 2.7 kg and 145mm of rear travel managed by the refined DW Link and 160mm fork, it is definitely the most versatile bike we have ever made. It also marks an important change in our approach to geometry.
The reach is almost one inch (2.54cm) longer than our HD4, winner in several rounds of the EWS, mounted with a 170mm dropper post and a super pedal friendly saddle angle at 76 °. The result is a bike ready for long outings, where riders truly let loose and enjoy. Other features include clearance for 2.6 "tires, low standover height, a threaded bottom bracket, internal cable routing, and room for all modern shock options to fit with a large water bottle inside the front triangle.
The most overused phrase for modern mountain bikes is likely "longer and slacker". Every manufacturer (IBIS included) is guilty of pushing these variables. Of course, a longer and more open geometry improves the downhill characteristics of the bike, but at what point is it too much? We felt we had arrived at the limit, and we have begun to work on saddle angles and fork offset.
With a particularly steep 76 ° seat tube angle, we have moved more weight to the front wheel. This translates to a front end with more precise steering. In addition to moving the seat tube forward, we also needed to adapt the position of the steer tube, in order to maintain the values of top tube, while generating more reach.
In addition to the steep seat tube, the Ripmo adopts a lower fork offset than normally used. The 65.9 ° headtube angle works like a 64.5 ° with traditional offset, without increasing the wheelbase. The stability of the slack headtube angle remains open without losing the agility necessary to make tight turns.
The geometry of the Ripmo guarantees a new level confidence and speed with its 29" wheels, and the stability of a modern enduro bike like the HD4".
BUSHINGS AND BEARINGS WHERE THEY NEED TO BE
If you ask an engineer, they will tell you that the bushings are lighter, stiffer, cheaper and require less maintenance than bearings. It is essential to use them where it really makes sense.
Bushings work best when used with high loads and minimum rotation, two things that bearings do not do as precisely. This is why suspensions manufacturers use them to fix shock absorbers to frames and we have been using them for the past 5 years on the Ripley, HD3 and HD4.
High load and minimum rotation precisely describe the new lower link of the Ripmo, which is where we introduced a new connecting rod on IGUS bushings. The new link is 80g lighter than its bearing loaded predecessor and much stiffer torsionally. The bushings are protected from the elements and last a long time. We are so convinced of this concept that we guarantee them for life. Do you have a problem? Call us and we will send you a new set.
WHAT'S BETTER THAN A DROPPER POST? A LONGER DROPPER POST.
This is why our frame is designed internally for a 170 mm travel post (150 mm on the Small), and riders with long legs can go with a 185-200 mm seat post. The extra space also allows you to
choose your frame based on reach instead of standover.
With a versatile platform like the Rimpo, you can choose the tires you prefer.
We have been pioneers with wide tires, including semi-plus tire widths up to 2.6 ". When combined with our 35mm rims these high volumes tires can be used at very low pressures, greatly increasing traction.
INTERNAL CABLE ROUTING
While all our bikes have internal cable routing, the Ripmo is the only model to have internal carbon tubes for cables, printed directly in the frame. Just put the
cable or sheath in one end and it will exit the other side without any special tools.
