  1. I am considering using a 20 inch (406) wheel with a Sachs VT-5000 drum brake on an RST Sprite TL
    suspension fork. Does anyone know if this combination will work or will the braking forces
    damage the fork?

  2. Combination will not work. The problem is not the stength of the legs BUT the size of the flanges
    and bulk of the brake actuator arm and hub flange. To start with the legs of the fork is already
    FAT. When you slide the hub into the fork, the bulky hub flange with the brake actuator arm cover
    hits the legs of the fork.

    I was intrigued with the quetion so physicall tried a few minutes ago.

    Hope this helps

    Thanks for checking. Sounds like it's either suspension or drum and I'd rather have the suspension.
    The fork has brake bosses, so it's not vital. I guess I'll use the drum-brake wheel and lever for
    trading stock. Some tandem builder may need it. The wheel is off a Bike Friday tandem.

    The upper-end RST 20" fork (900?) has a wider spacing between the fork legs than the Sprite. This
    will allow you to use your drum brake (or a disc brake, if you like).

    I haven't checked this physically- I recall that Zach told me about the RST-900 fork a while back.
    It's not on the Hostel Shoppe page, but the Meks and White forks are: hostelshoppe.comcgi
