So, Ibis has been open about working on a 29er for a couple of years. It decided to unveil it at Eurobike even though it’s not going to be remotely ready to buy until next year – just in case people thought they were just joking.
The story goes that back in 2008 Ibis was looking to make a super light, short travel 26in race bike as its next frame, but then compared to its 140mm bikes, 100mm seemed a little tame, so it turned its attention into making a 100mm 29er using the same compact design where the DW-Link suspension doesn’t use links… it uses eccentric pivots, running on bushings.
Target weight for the reincarnated Ripley was for a sub 2kg (4.4lbs) frame. This is literally the first one out of the mould and is in no way a rideable sample, however it gives an idea of how the finished one will look and it’ll let you puzzle a little over how it works – which is essentially just like a regular DW-Link Mojo – only there are no links.
There are also no bearings either – the compactness of the design meant that normal cartridge bearings wouldn’t fit so there’s a special eccentric pivot that runs on Norglide bushings. These are adjustable (by means of two bolts accessed through those two rubber plugged holes) and should be good for around 20,000 hours of riding…
