Dial In Your T Line Gearing Without Changing Cranks
This Ti Parts Workshop aluminium spider lets you keep the stock Brompton T Line crank arms while opening the door to a wide range of chainring options. It replaces the original direct-mount ring with a 130 BCD five-arm spider, so you can fine-tune gear range up or down with different ring sizes and styles.
CNC-machined from 6061-T6 aluminum and finished in black, it’s light, stiff, and designed specifically around the T Line’s FSA direct-mount interface. The result is a clean, factory-style upgrade that makes future gearing changes as simple as swapping a standard road chainring.
Engineered Simplicity
- Designed for Brompton T Line stock cranks, keeping your original carbon crank arms in place.
- Converts the factory direct-mount setup to a 130 BCD 5-arm spider for broad chainring compatibility.
- Makes it easy to choose gearing that suits your riding: smaller rings for hills, larger for higher cruising speeds.
- CNC-machined 6061-T6 aluminium keeps weight low while providing solid, precise chainring support.
- Black finish blends neatly with most T Line builds; a tidy upgrade that looks right at home on the bike.
