1" Threadless Rigid Mtn Bike Fork

Hi guys,

I have a bit of an issue that I need some advice on.

I recently bought a late '90s Trek 830 to use as a local commuter. I put slicks on, etc (the same things everyone else does in the MTB turned commuter). This bike has a crappy factory suspension fork that I would like to dump for a rigid fork. My problem is I can't seem to find any forks that would fit. It is 1" diameter and threadless. All I see online (nashbar, surley, ebay) are all 1-1/8" diameter, or 1" and threaded. Are forks that are 1" and non-threaded out there? Are they rare? I really don't want to dump too much into it, but really would like to go rigid.

Thanks for any information.

Best.

Is that a steel framed bike or an aluminum frame bike?

If it's a steel bike and it has a 1" fork, then it may have originally come from Trek with a threaded fork. You should be able to find a used Trek original 1" thread non-suspension fork at a bike coop, OR on a donor/parts bike.

If the bike has an aluminum frame then it should have come with a suspension fork with a 1 1/8" threadless steerer. Double check the size.

Your google foo is poor. Dimension makes a 1" threadless fork for 26". You can find them on-line for around $50. QBP also carries them so you can also order it from most any local bike shop.

It's a steel frame. A nice, ugly, heavy, bright yellow 22" frame. However, the guy kept it in like new condition, and it's one of the few bikes that just really has a comfy fit. It has pretty decent hyper light handlebars and stem, and cane creek headset. Considering going threaded would mean replacing some of that as well, no?

Looks like it'll cost me around $65+, which is probably the best bet. Of course something vintage and less $ might be nice too. May have to wait till christmas. Thanks for the info.

I noticed you've got an 820 set up for touring. Are you using the Dimension? If so what do you think of it?

My 820 has a stock 1" threaded rigid fork.

I did put a Dimension rigid fork on my wife's MTB commuter, in 1 1/8" though. It replaced a low-end low-travel stock suspension fork that had worn out to where it was always compressed. If I remember correctly, the axle-to-crown length of the Dimension (395 mm; same as the 1" version) was shorter than the suspension fork even when compressed. So, the frame's head tube and seat tube angles steepened and I needed to raise the handlebars to compensate, but in the end she couldn't tell the difference in geometry. Mountain bikes, compared to road bikes, start out with slacker angles anyway. Overall, it's worked out really well.
