Rear Shock Absorber Spring - Red 550LBS - Surron Light Bee

£73.28
/
This is an uprated (higher strength) rear shock absorber spring for the Surron Light Bee.

Whilst the standart 450Lbs spring is too soft for many drivers, the 550Lbs red version fits riders with a weight of around 70-80kgs.

If you've found the original rear shock absorber too soft, this upgrade will transform the handling of the bike - selecting the correct spring rate is one of the most important steps of setting up your bike's suspension.
If you weight over 80kg, you may select the alternative 600Lbs spring variant.

The Speedi is amazing removes the bogging down feeling once your bike reaches it limiter. The Speedi allows you to go as fast as you can pedal or run out of gears. Really easy to fit took approx 30 mins from start to finish and I was being really careful. My YT decoy is a total different bike now.
