Ultimate Crankset Upgrade for Brompton Folding Bikes
The White Industries R30 Crankset transforms Brompton performance with precision-machined components built to last a lifetime. Made in-house at White Industries' California facility from 2024-T365 aluminum, this road-oriented crankset brings over 30 years of manufacturing expertise to the folding bike world. The 30mm spindle provides exceptional stiffness and power transfer compared to stock Brompton cranks, while the modular design allows easy chainring swaps to dial in your perfect gearing for city commuting, touring, or spirited riding.
The R30's road geometry suits Brompton's compact frame perfectly, with a Q-factor of 158.5mm and 132mm width between crank arms that clears chainstays without issue. Available in six crank lengths from 155mm to 175mm, riders can optimize their fit and pedaling efficiency—shorter lengths work particularly well on Bromptons for urban riding and quick accelerations. Choose black anodized or polished silver arms with eight extractor cap color options to match your bike's aesthetic. Requires White Industries 30mm bottom bracket (sold separately) and MR30 chainrings (sold separately).
