Momsen Bikes from South Africa has been working hard to introduce their newest carbon full suspension model dubbed the VIPA mtb, for the season upon us. here
They have reported the new VIPA will utilize 80mm of rear travel, pushing for it to be a perfect bike for the cross country and marathon racer market, by giving it extremely efficient pedal transfer qualities.
To jump into the blood and guts of what makes it all happen for stardom status, the Momsen frame’s suspension engineering was handled by a renowned suspension designer Patrick Morewood, as the signature on the top tube suggests. It also uses modernized features such as a press fit B.B., a 142×12 rear axle setup, a tapered 1.5 headtube shown below. But it’s interesting Momsen have chose only to contain the dropper seat post cable internally, and then ran the rest of the routing down the down tube on the outside. We’ll give it a season, and most likely there will be continued refinement? None the less internal cables are merely just a “maintenance convenience” and “aesthetic”, they have nothing to do with how well a mountain bike truly rips up or down a trail.
For the weight department of the frame, they have reported a medium prototype sets the scale at 1800 grams without the rear shock. Seems plenty light, and race worthy in the 29erCafe department.
Very cool Momsen graphic logo as well of a snake on the rear of the seat tube above. They are connecting the RockShox Monarch rear skock directly to the seat stay, which is then connected to a full carbon rocker arm that is depicted in the photo below that.
Momsen have also made a key note to report as well that this design is not a Specialized FSR copy, because they have placed the rear pivot location behind the rear axle on the seat stay, thus the FSR is the opposite located in front of the rear axle path and lower on the chain stay.
Momsen will be offering the 2013 rides for sale as a frame only option or in complete with drive train models as well.
This was the Vipa ride setup Nico rode in last springs Cape Epic Race, SWEET! Looks very fast.. and sounds as though it performs equally as fast.
