Converting a Sprung Fork To Rigid?

It seems like I could just drill a hole through, put in a pin and be done with it.

Then, again, it seems like that may cause a weak point and cause the fork to break causing Old_Dude to crash & suffer agonizing pain (which I really prefer to avoid).

I'm thinking of converting a Judy TT to rigid. I'm sure I can figure out a safe way to do it - any suggestions? It'd be cool if I could do it so the lockout was "quick", not requiring the removal of the fork, or lots of time &/or tools to convert from rigid to sprung. Like if I could snap on a piece of PVC to the exterior of the fork legs (where the boots are now) to prevent the fork from compressing, or something.

As I understand this fork, isn't the spring only in one leg of the fork? I was thinking also of putting a spacer (like pvc pipe, or something) inside the other leg (or both legs and remove the spring in the sprung leg) to prevent the sprung status of the fork. This would be a much more permanent (safer?) method of converting the fork to be static/rigid.

Anyone have any ideas? Anyone ever done something like this successfully?

I already thought about getting one of the Surly rigid forks, but geeze - at $58???? Yeah, I'm cheap - very cheap.

(sorry if this thread was already posted - I didn't search first)

Thanks,

Nashbar has a rigid fork even cheaper. $30-50 is not a lot when you consider some of the risks you take in jerry-rigging something.

Or maybe you could just fill the sucker full of oil or something so it can't move...but why do that when a real rigid is cheap and lighter?

As far as I can tell, Nashbar's fork doesn't compensate for fork travel, which changes the geometry on the bike by 80mm - it'd be like riding a bike that was almost 3" lower in the front. The Surly fork compensates for the 3" difference (it's longer), which doesn't change the bike geometry. I think the Surly 1x1 fork is 2 1/2 pounds - right now all they have in stock is white. Black is scheduled for sometime in October, I think.

Anyone else besides Surly make a "compensated" rigid fork?

Thanks,

OD

I would get a kona p2. Maybe the best "cheap" rigid on the market. A truely nice, suspension corrected, triple butted CrMo rigid fork. The distance from the center of the axle to the crown race is 410mm. This fork would look great on any type of mountain frame. Especially for you single-speeders looking for a light weight rigid fork. You can fit a 2.6 nokian, very solid tracking and ovver all just a sweet fork. The fork weight alot less then that tank of a surly fork or nashbar special.

Here is a link to buy one new:

I would try your local lbs first for take offs. This would be much cheaper.
