650b mountain bike wheels were one of the big trends at this month's Eurobike show and it looks like they're even making their way into downhill racing.
Bionicon's B-Post dropper seatpost
Germany's Bionicon were showing off a very interesting prototype at Eurobike – a dropper seatpost integrated into one of their frames. This saves weight, as the shaft slides directly into a specially modified seat tube, removing the need for a separate lower tube.
Bionicon reckon the production B-Post will weigh sub-300g – not much heavier than a standard alloy post and a full 250g lighter than a RockShox Reverb.
