New 2021 version with improved (wider) easy wheels

Option 1: Extender only (no easy wheels)

Option 2: Extender only + 2 easy wheels


Extender description:

Your L/R-model Brompton can tilt towards the right when folded, especially if you mount a heavy bag on the front carrier block. Isn't that irritating and won't you be worried that it will get scratched after falling over? The Extender Bar is the solution! With an extendable axle, it will provide extra stability to your folded Brompton. Simply retract it when cycling. CNC-machined out of aluminium alloy. Suitable for all Bromptons with rear triangle bracket sizes between 110-115mm

Easy wheels (optional):

Wheel width: 15 mm

Wheel diameter: 60mm

Using flat type o-ring with bigger surface contact for greater stability.


NOTE: For some old Brompton racks (depending on the year of production) you will need M5 (5mm) bolts.

Do not load weight over 30kg when extended, this will cause deformation or breakage of the axis (For frame protection. X-Roller will bend first before Brompton frame ends break.)

Do not drop your bike when X-Roller extended, this will cause deformation or breakage of the rod.
