Some technical aspects :

Chubby colour rear shock for brompton was designed to meet the need of riders with various weight.

Features:

• PU elastomer from Germany more durable. Most of the load is on spring, elastomer only used to prevent resonance effect.
• Top down covers smooth curvature design consistent with Brompton frame.
• Top down covers CNC machined, wider than spring shock axle bolt plate, better protection to parts.
• Spring made in Japan with high quality and consistent rebound factor and durability.

We know that there are Bromptoneers with weight close to brompton suggested limit, and the stock stiff suspension block just not stiff enough.

Or you are aiming for speed, won't let go any pedaling power.

That is why we offer more choices on stiffness for your need. Please refer to the test ride videos to make your pick.

(The following test videos will show you how our rear shocks react on various road condition. Please note the rider weight was about 75 Kg in all videos, so you can have a rough idea how the rear shock will react on your weight. Please specify your stiffness choice during checkout.)

Light weight version (recommend for rider weight < 65kg)

Mid weight version (for rider weight in 85kg to 65Kg)

Heavy duty version (for riders weight > 85kg)
