Description

The Pulse is Eclat's switchable cassette hub. Their patented switch drive system lets the hub run right side or left side drive using the same driver and the same hub shell, so one hub covers you if you change the way you ride.

Since the first version the pawls have been improved, the driver function tweaked and the ratchet ring design updated. It comes with Eclat's Viper nylon-fibreglass hubguard, and an allen key inner axle keeps maintenance simple.

Features

Switch drive, RHD or LHD. The patented SDS system moves the driver from right side to left side using the same hub shell and driver, with no extra parts.
Viper hubguard included. Eclat's nylon-fibreglass hubguard comes in the box, so the shell is protected from the first grind.
Male or female axle. Choose a 14mm male or female hardened heat-treated chromoly axle to suit your frame and your pegs.
Allen key inner axle. You can strip and service the hub with an allen key, so maintenance does not need special tools.
9t driver, 36 hole. Runs a 9t driver with an 8t available separately, in 36 hole drilling at 497g with a 110mm axle width.
