    TCMB's Quest for Better AER48 performance - DIY Valving

    Lately, I've been experimenting with some various shim stacks in the AER48 forks on my MXR to improve its performance (for me). I'll start documenting my journey and perhaps some of you may find it helpful in tweaking your own suspension and finding the best setting for you. Don't be scared...

    Jeff Walker rode my EXR!

    Linked up with Jeff Walker at Fox Raceway yesterday and let him take a spin on my EXR on the vet track.

    Dubya World Vet Championship at Glen Helen - few clips

    Raced 30+ again this year at the world vets at Glen Helen.

I went 3-5 for 4th overall against about 30 riders. I had the speed to...
