Two years ago Rocky Mountain surprised the cycling world at the Sea Otter Classic with a prototype bike built around what at the time were best described as mid-fat tires. This progenitor of the plus sized craze was created for a very specific need — getting rowdy while bike packing — but the concept has since picked up steam.
Rocky Mountain’s newest plus offering is a 130mm travel frame built off the same platform as the 29er Instinct. Capable of accommodating up to 3.25” tires, the Pipeline will come stock with 2.8” rubber.
Unlike some of the latest crop of plus sized models which are aimed at the lighter end of the trail segment, the new Pipeline is designed for tackling technical trails.
Using Rocky Mountains adjustable geometry system of interlocking flip chips, the frame can be tweaked to have anywhere from a 67.2-68.8-degree head tube angle, a variable BB drop, and more progressive or linear performing suspension characteristics.
Complete bikes will ship with a 150mm fork and the frames are 1x specific only. There are two options: The 770 MSL, which retails for $4799, and the 750 MSL which costs $3999. Both feature mostly Shimano XT level drivetrain bits, but the 770 gets a Fox fork and shock, while the 750 uses a Rockshox Yari fork.
The frames will be available in S, M, L, XL. We’ll have more details from the Sea Otter Classic later the week. In the meantime, click over to page 2 to check out our interview with the Rocky product development team.
