"HSE" Clutches

$146.25 ~~$195~~ In stock

GSI "HSE" (Hall Sensor Engagement) Clutches are CNC’d out of 6160 aluminum with a custom made spring for a more controlled pull and modulation. The internal hall sensor doesn’t wear out over time providing you a lifetime of use and has an adjustable throw height. Unlike most clutches on the market that have a very loose and floppy feel, the GSI "HSE" clutches have a firm controlled pull from the custom spring. Made for the those hyper starts off the line and great for fuel saving on those long endurance races.

The pull on these is so much smoother than the stock setup, and the spring tension feels dialed in right out of the box. Machined aluminum body looks great, and I like that the hall sensor won't wear out like a mechanical contact would.

Swapped these onto my bike after dealing with cable stretch for years, and the difference is night and day. The hall sensor means no more adjusting cables every few rides, and the machined aluminum body feels solid in hand. Modulation through the lever travel is buttery.

The pull is definitely smoother than the stock lever and the modulation feels nice, but the spring is a bit stiffer than I expected for trail riding. Fit and finish on the aluminum is clean though.
