THM will present in 2017 a new Aluminium Spider for the Clavicula M³ MTB crank to complement the range of the already available 1-speed, 2-speed and 3-speed spiders.
The new spider is a 1-speed type with 104 mm bolt circle for the standard version (49.5 mm chainline) and alternatively for the Boost version (52 mm chainline). Chainrings and bolts will be available as an option.
With this product we now present the lightest MTB crank with a BCD 104 1-speed drive in 32, 34 and 36-teeth version. It is also possible to install 30 teeth with a slightly modified Praxis Works chainline.
