Inpulse bikes head honcho Cédric Fontenoy has sent us some pictures of the new R26 and R20, which arrived on the market a few weeks ago and have already enjoyed some success.

These frames have been through several evolutions, each sexier and more effective than the last. With a new ‘race’ look that everyone will love, with neat graphics and paint job, this new version looks great! The frame has also been considerably lightened: The 26” model has lost almost 600g and the full bike weighs in at just 8.5kg for the production model. This is not only down to the lightened frame, but also the impressive new spec that includes some new carbon Inpulse bars and hubs!

The rest of the spec is in a similar vein, an ultra-stiff, ultra-light fork (730g for the HS33 version with uncut steerer tube), a new freewheel with 108 engagement points and a new forged stem. The 20” model adopts postmount disc mounts, which are adjustable to allow for chain stretch.

In short, the 2011 vintage Inpulse bikes are pretty exceptional! Here they are in detail, more info on the Inpulse website.
