BMC Fourstroke FS01 29 – first look

Swiss company's new full-suspension 29er looks promising

The Fourstroke FS01 29 is the top bike in BMC’s new 29er full-sus lineup. It features an impressively light full carbon frame, top-of-the-line components and a price tag to match. Our initial impression is that it does a good job of blurring the lines between cross-country and trail bikes.

As the name implies, the Fourstroke FS01 29 has 4in (100mm) of suspension travel. It shares a similar suspension design to the 26in BMC Trailfox TF01 (a rocker link driving the rear shock and a lower link mounted directly above the bottom bracket) in a shorter travel, race-oriented package.

The Fourstroke FS01 29 is offered in three build kits: Shimano 3×10 XTR, as well as two 2×10 configurations with SRAM XX and X0 (the SRAM XX kit is not available in the US).

Our XTR test bike retails for US$8,499 and tips the scales at 11.3kg (24.9lb). The frame with rear shock and associated hardware weighs 2,040g (4.5lb). Budget-minded riders will be glad to know there are also more affordable models with a carbon front/aluminum rear triangle, as well as a full aluminum frame.

The Fourstroke series is designed with endurance/marathon racing in mind, but as the video below shows, it looks to be a capable short-travel trail bike as well.
