The last CNC technology is also available for small wheelers. Pneuma cranksets brings the ultimate crankset technology to our commutes.
Most folding bikes are built with heavy cranksets with outdated square taper bottom brackets. To make things worse, finding high quality and light cranksets for folding bikes is not an easy task because they need MTB style spacing and road style chainring sizes. This is why most standard cranksets are poor fits for folding bikes. Ridea designs their cranksets for folding bikes with the correct specifications fit the requirements of folding bikes.
Pneuma BCSA is our best ever single chainring crankset for Brompton, Birdy, Dahon, Moulton and many other folding bike brands.
*Chainring needs to be purchase separately.
