This is the 3rd generation of the jack-of-all-trades Ripley LS, featuring an all new frame with increased stiffness and clearance for the new generation of 29" tires. The proven dual eccentric dw-link suspension keeps the tires in touch with the ground so your power is applied efficiently.

The new swingarm accommodates the 2X Shimano side swing front derailleurs including Di2 (and of course 1X). The front derailleur mount doubles as a nice upper chain guide mount.

Clears a 2.6" tire

We pioneered the wide rim revolution a few years ago. The new crop of 2.6” tires when paired with our 35mm internal width rims deliver elbow-dragging traction. You can run these high volume monsters at low pressures, delivering incredible traction and stability.

dw-link Suspension

The dw-link suspension design is universally acclaimed as one of the best bicycle suspension systems. We use it because it’s the best we’ve ridden. The Ripley LS uses the EWS World Championship winning V5 dw-link. The dw-link gives the suspension a wide flat platform across the pedaling range for maximum efficiency and bump compliance. Simply put, it tracks the ground without sapping your energy. If it has any shortcomings, we've yet to find them.


The suspension operates via innovative dual-eccentric links. Instead of using external linkages like we do on our longer travel bikes, we were able to construct the Ripley with two small eccentrics, hidden inside the seat tube, which act as the suspension linkages. The bearings are located inside the seat tube, where they are shielded from wheel spray and contamination. The look is very clean, as everything is hidden inside the frame. 

The eccentrics were a huge engineering challenge that resulted in many nice benefits.

The Carbon 831 Lab

We built our first carbon fiber bike over thirty years ago and we’ve been building full suspension carbon fiber mountain bikes for nearly fifteen years. To further advance our understanding of the material, we’ve created a small scale carbon manufacturing facility in our Santa Cruz, CA headquarters. The first project to emerge from our Carbon 831 lab is the size small Ripley LS. You can learn more about the Carbon 831 Lab by clicking below.

Our Small Project

When we first produced the original Ripley, Roxy made damn sure there was a size small frame. At the time, however, 29ers weren’t yet as widely accepted. Many riders felt they were only for tall people, so the demand wasn’t there. We sat on a number of size small frames and when the Ripley LS came around, it didn’t make sense financially for a small company like Ibis to bet against the trends. Find out the story behind the new size small by clicking below.
