Meet Grimlock

We ship our handbuilt wheels all over the world and it’s essential they arrive true and stay true.  Grimlock helps us achieve this.

Grimlock is a special tool we developed and built to pre-stress our wheels.  If you’ve ever ridden a new bike or wheelset and heard pinging from the wheels, or if you’ve ever had a wheel go out of true or loose tension shortly after being built then you’ve seen inadequate pre-stressing.

Grimlock ensures your wheels stay true, no matter how much or how hard you ride them.
