98 Trek 930
 
I've been looking for a rigid fork for my 930. anyone have a clue as to which ones will fit?
I know I can use a Surly 1x1 but I'm open to other suggestions...
It's a 98 so there are the "suspension" issues. 1/18" if that helps.

Gonna be a Touring bike so no need for anything fancy.

Thanks!

Dimension, Origin8, etc etc... there's a ton of different ones. Some are even exactly the same. The Surly may bring the front up a bit, I think Dimension makes a 395mm axle to crown fork that may preserve ride height more closely.

PapaToad 03-09-12 08:15 PM

I've looked at those too. I'm kinda hoping someone might have a "takeoff" suggestion?
Thank You for the suggestions!

Any 26" threadless take-off fork should work. Shops sometimes have a few lying around.

Every shop I've talked to here in the Bay area of course wants to sell me a new one.
I'd really like to keep the expense down on this build until I'm sure I like the frame.

I LOVE the "we can order you one" answer... I can order one.
Thanks again!

How long is your headtube? I can probably source one. Cantis, correct?

If you are concerned about the frame geometry switching to a rigid fork, set up the current suspension for the ride you're used to, the fork will have a certain amount of preload. Climb onto the bike, and let the fork settle. Have someone measure the drop out to fork crown distance. Use this to buy your rigid fork corrected for suspension.

I probably have one in a bin somewhere...

I have a couple steel Trek frames, one is slightly damaged. So at least one orphan fork, what color is your '98?

I have an original 950 frame and fork, it is a medium size, not sure exactly. It has that beautiful fat fork, really nice. Both frame and fork are stripped of paint. Would prefer a trade over $. PM me.

PapaToad 03-09-12 11:17 PM

I don't care about the color as I'm going to do a top down rebuild. Paint is NO issue.
Cantis are the plan.
Headtube length... uh I'll have to go measure. Guess I should have done that BEFORE I started asing questions. I'll do that tonight.
Thanks For all the ideas!

Can't PM yet... need to talk more. Yeah right!

Anyone want the old Rox Shock? seems in pretty good shape.

My wife needs a suspension fork for her 97 GT Avalanche frame. Again, what's your head tube length? ;)
Can you post pics of the Rock Shox?

PapaToad 03-10-12 12:56 AM

I'll go measure it right now. Metric or S.A.E?

PapaToad 03-10-12 01:01 AM

104mm seem right? Top of cup to bottom?
Shock is the Indy S.

WNG 03-10-12 01:08 AM

I'm assuming this fork is threadless, right?
head tube measurement would be just the frame's head tube length, excluding all else. But it's not a good estimate of the steerer tube's length.
To try to get the steerer tube's length, measure from fork crown race to the top of the stem if there is a cap on it. Then subtract 5mm. If you have a spacer above the stem, then simply to the top of the spacer and cap.

PapaToad 03-10-12 01:03 PM

OK, the Head Tube is 90mm and the Steerer Tube is 160mm. Frame is black.

WNG 03-11-12 08:44 PM

Sorry for the delay, out all day on an emergency.
Well, I just measured the frame, and darn....its head tube is 110mm. 20mm too short. :(
