Ibis have just announced the new HDR, an evolution of their all-mountain HD that's lighter and stronger, with support for the latest drivetrain and suspension components.
The bike comes in two variants – the 26in HDR and 27.5in compatible HDR 650. Both models share the same frame, and you have the option to swap wheel sizes at a later date through hardware changes. US pricing is detailed below, with UK cost listings to be confirmed.
The HDR shares its geometry and DW Link suspension kinematics with the HD. It also gets the same two travel options as the previous generation bike – 140 or 160mm. Once fitted with 27.5in hoops, the HDR chassis can deliver 130 or 150mm of travel.
Converting a regular HDR to a 27.5in-ready machine requires swapping out the US$25 Limbo Chips (Ibis' name for the forward shock mounting hardware), and the shock for a shorter model (the same as on the Mojo SL-R).
If you want more travel in a 27.5in format then the frame should be set in the 160mm travel mode, and a 5mm travel-reducing spacer has to be added to the shock. Ibis recommend deflating the shock to check for any potential contact issues due to tyre size variation. The bike offers 150mm of travel in this mode.
The new HDR has typically shaved around 0.3 to 0.4lb from the previous generation HD, yet Ibis claim more strength and equal stiffness to boot.
Suspension hardware has been shifted to make way for ISCG 05 chainguide mounting functionality, along with increased front derailleur compatbility for double and triple setups. It will be SRAM XX1 compatible too.
Additional clearance has been made to accomodate the new, lighter Fox XV air cans used on their CTD shocks. There will also be room for their new Float X piggyback shock.
