THM Fibula carbon brakes


Orange patch: shipped about 12 weeks after order

The set includes:
2x brakes (front + rear)
Screws set
4x pad holders
Pads are not supplied

New Fibula brings THM legendary brake into the modern era of wide rims. For more than a decade, the super-lightweight Fibula equaled the performance of top models by major vendors, at half their weight. THM got this great performance by fully exploiting the properties of carbon fiber.

For this new brake design, THM moved to resin transfer molding (RTM), a process that improves product tolerancing, consistency, and strength-to-weight, and has less environmental impact than traditional carbon fiber fabrication.

Even the return spring is in composites. An adjustable cam means it’s compatible with rims of 19–30 mm width without changing the cable clamp point, with no effect on lever modulation — this makes it ideal for a bike used with various wheelsets and tires up to 28 mm wide.

Pull ratio is optimized for Shimano, SRAM, and Campagnolo levers, and at 119 g for the pair, new Fibula, like its predecessor, remains the lightest brakeset available.



119 g without pad holders (60 g front / 59 g rear)
+10 g the screws set
+18 g the 4x pad holders

Total is 147 g  (with pad holders, without pads)


Useable for wide and narrow rims (from 19 mm to 30 mm) without changing the cable fixing. 
Perfect for changing between wide competition wheels and narrow training wheels.
