BMC is restless in their pursuit of perfection. Because of this, they re-engineered their popular Speedfox platform, and the standard-bearer, the Speedfox 01. This is a trail bike that has improved it’s climbing, it’s descending, it’s overall performance. It still features both 27.5 and 29er wheel choices, because they both believe big rolls better and believe people should choose the size that best reflects their riding needs.
The change people talk about first is a new technology called Trailsync. It’s a cable-actuated handlebar-mounted lever system that simultaneously drops the seatpost and opens up the rear suspension. Ride with your saddle high and suspension firm for the climbs and flats, drop it a bit for rough stuff, drop it all the way when letting it all hang out at high speed. The drop is 80mm for the Small, 100mm for the Medium, and both the Large and XL have 120mm. There’s a stop 35mm down before dropping the whole way. BMC routes the cable internally to both the shock and the post. The post itself is an alloy mast with a post-topper similar to what you find on seat-masted road bikes. You cut the mast to get close to the right size, and then fine-tune with the topper clamp.
