I recently purchased a used 16" Rockhoud and would like to put a rigid fork on it. Most forks seem to be measured axel to crown. What should this be to take the place of the 80 mm fork the bike is designed around?

Howdy,

Do you have a serial number from the bottom bracket of your frame? Depending on the vintage, the Rockhound could be 73mm or 80mm corrected.

The serial number is not real easy to make out. 0, 3 and 8 seem to look alike. But, my best guess is J 02302. The 02 at the end is stamped deeper than the other numbers, or possibly after paint.

I was told it was a 2003.

Hello rpiontek,

Your frame was set up for 73mm travel. Expect to use a rigid fork with an axle to crown of 425mm.

Best

Thanks Dave, I really appreciate it.

Hi everybody!

Viscious cycles has a nice table about rigid fork length, and offer several lengths for different suspension corrected lengths. For the 80 mm variety, the Kelly is a great bang for the buck.

Just did 50 miles of racing on Sunday. Four laps on the geared bike and three on the Ruffian, 15 minutes after geared bike. I was just as fast on laps 5-8 on the SS !!

29'er SS Ruffian, here I come!

Cheers all.
