new fork needed for Specialized stumpjumper fsr

Hi everyone,


just picked up a 1995 specialized stumpjumper fsr that had the front fork replaced with a static fork. Recommendations of suspension fork replacement within reasonable budget appreciated!

Maybe you can get a fork from one of the many folks here who have inquired about replacing their suspension forks with rigid ones.

The stock fork was a Rock Shox Mag21... a great fork in it's day... travel was a short 60mm or so... if you go with a more modern fork, don't get greedy by adding more travel past about 100mm, or the bike will steer slowly. It is a 1" threaded steerer tube type, if i recall, so obtaining the correct length steerer tube will be important, also... the fork that is currently in the bike will serve as an example of correct steerer tube length. Post a pic of the bike, if possible.

V-brake or disc brake?
For V-brake, your options are going to be very limited, and a static (rigid) fork is likely preferable to most of the available options.

Suntour XCR is a decent fork. Beyond that you're looking at whatever you can find and rehab on CL/ebay.

Remote lock out will cost you more, Lockout is useful if you ride on the roads much.

I just checked Bikepedia and catalog scans to confirm. The '95 Stumpjumper was 1 1/8" threadless, which ought to expand AKHIker's options.

In 1995, 60mm was the Long Travel version, normally this had to be done using the RS conversion, as it was 46mm travel stock (the 1995 catalog makes no mention of travel).

As noted, by 1995, almost all manufactures (Marin being the big exception) were using the Aheadset system, including Specialized, by 1995, 1 1/8" was standard as well (Bontrager & Univega being the only major exceptions) .

For a replacement fork, the biggest issue will be if you want to stay with rim brakes, of stick a disc on the front, rim brake forks are available, although will need to be searched for, anything with upto 100mm travel will work fine with the frame, although if you looking to go upto 100mm, you will probably want to get a shorter stem to go with this.

AKHIker, Howdy;

Last summer I bought this one;
https://www.bikeforums.net/18839872-post5000.html
This what yours looks like???

It has the original front fork which I have replaced with a Surley Ogre front fork
that is suspension corrected and works fine
The Mag-21 is in need of repair but ... I could send it to you for the cost of postage
if you truly think you might want the headache of finding a rebuild kit for it plus the
tools and air pump etc. PM me and we can work out the details.

I agree with most of what you've said. Finding a good fork with cantilever mounts could be difficult. Finding a bad fork with cantilever mounts, on the other hand, is relatively easy. I suggest the former. Manitou makes the R7 with cantilever posts which is an air fork with lockouts. Manitou forks are pretty good. They aren't Fox's but they are still good forks. The R7 is a bit pricey however. Tree Fort carries them (currently on backorder) for $450. Alternatively, you find older forks on Fleabay but you need to be careful. Some are better than others, of course.

I don't agree on needing a shorter stem however. Raising the front of the bike with a longer travel fork doesn't change the saddle to handlebar distance.

No mine has the rear shock on it. thought it was a 95. Thanks for the offer on the old fork but not sure I want to go through the rebuild. I might be crazy enough to do it if I had the parts all here...

v brakes with rear shock. Is static really preferable when you have the rear fox shock?

Oh, well ... I don't have any plans to pitch it out any time soon.
Let me know if you change your mind.

The problem is that there aren't really any good options. You could switch to front disc brakes, but that would require a new wheel.

Basically, all of the options cost more than the bike is worth. Trolling eBay for a used fork is probably your best bet.

Not really. The front shock does more than just provide comfort. It helps a whole lot with control, especially in ruts. Rigid forks get trapped inside ruts where suspended forks climb out of them. Bottom line: fewer crashes with a suspension fork.

The rear, on the other hand, doesn't do anything for control but it does help with climbing.

I have an 80mm Fox Float with rim brake bosses (and disc tabs) that I might be willing to part with. It's in good shape and doesn't need an immediate rebuild. PM me.

On the other hand, there's no problem running mechanical disc front and rim rear. I have a bike set up and there is no difference in the way the brakes work. A hydraulic front might be problematic...the "feel" is too different.

This would probably fit, and it's a quality fork.
RockShox Recon Silver, 26, 100mm travel, Solo Air with 9-QR and bosses for V-brakes.

RockShox Recon Silver TK MTB Fork 26" 100mm Solo Air 9mm QR 1-1/8" Rim / Disc | eBay

At $190, it's a decent buy. Your only cheaper options are going to be used or things that aren't good. Cycommute's offer of a Fox isn't a bad option.
