It may seem a bit odd that Ibis are only just now releasing their 29″ wheeled model to the world. After all the clamour appears to be about, if not for, 27″ wheeled bikes. The reasoning is pretty simple though, Ibis wanted to do it their way and they wanted to get it just right. To get to the point where they are happy enough to unleash the Ripley has taken six years of research, innovation and manufacture. This wasn’t just a matter of taking their popular Mojo and slapping some bigger wheels in, the Ripley is a totally new design, not even the DW-Link is the same. Rather than using the usual external linkages Dave Weagle (DW) worked out a way to condense the same system into two eccentrics in the seat tube.
120mm rear travel.
Designed around 120-140mm forks.
5.2lbs frame weight with Fox RP23 CTD.
Tapered head tube.
Internal cable routing.
Dropper-post hose guides.
142mm Maxle rear axle.
The aim with the geometry was to get the feel of 26″ wheels but with the benefits of bigger wheels. This involved playing around with headangles, fork rake and fork length to get the feel that Ibis wanted from their 29er. Ibis stress the importance of putting a fork with a 51mm offset into the front of the Ripley, anything else and you won’t be getting the ride you should. Looking at the numbers it seems Ibis has gone for a very modern long front end coupled with a short back end, something we’ve noticed on the better 29ers we’ve ridden.
Ibis is often seen as being a bit eccentric, now it’s very eccentric. By cramming all the claimed benefits of the DW-Link into two eccentrics rather than linkages Ibis have been able to save weight, keep the moving bits away from dirt make the design cleaner (for more on Ibis and it’s take on industrial design check out Issue 80 of Singletrack) . As if that wasn’t enough Ibis also reckon this design leads to a stiffer design than could be achieved with the regular DW-Link.
The Full Story.
Scot Nicol can spin a yarn better than most so rather than chopping up his words you can read the full low-down on the Ripley from Chuck Ibis himself here:
Needless to say we’re keen to get in line for a play on a Ripley, it certainly ticks a lot of boxes, flicks a lot of switches and floats a raft of boats.
