The handbrake is great, the grip is just awful, its like the grips on a £20 Kids scooter

Upgrade to the best grips in the business with this adaptor. It will allow you to fit a Mountain Bike lock-on grip to your handbrake

Either buy the grip on its own or with one of the grips I sell. Comes with the bolts to mount it.

If buying your own grip please dont skimp on quality with cheap chinese grips, buy decent MTB grips and you will feel the difference! I sell with 'DMR Deathgrip' grips because they are awesome and a great balance of comfort looks and price with many colour options so they are my recommended grips but any plastic core lockon grips will fit, good brands include DMR, RaceFace, ODI, Renthal, Nukeproof, Ergon and more*. 

Guaranteed fit grips that I have tried:

DMR Deathgrip

Brand-X Knurled Lock On Handlebar Grips (The red one in the thumbnail)

Nukeproof Neutron Knurled Lock On Grip (the double lock-on one in the yellow photo)

 

I recommend grips with a single Lock, though a double lock grip will work (it just wont look as good) there is a picture in the images to show you the difference

I dont carry all colours in stock, but I can get hold of them very quickly

*Please avoid ProTaper Grips, I have tried these and they do not fit well due to the internal taper
