Unknown fork travel?

I have a junk unadjustable fork. I'm pretty sure it wont travel the whole length of the stanchion tubes. So how do I determine it's travel, to get an idea of what to replace it with?

tie a ziptie around one of the fork legs and fully compress the fork. Where the ziptie is, is where the for travel ends. Just measure.

Thanks for the quick reply.

When I push my 220lb of body weight down onto the handlebars, I couldn't get it to bottom (measure travel that way).

Well give em a wham! go riding with them, and drop some curbs. Make sure the ziptie is tight so it wont go down again. Works like a charm.

Or if you can take the spring out you should have no problem compressing the fork. If there are two springs i would leave one in however, just to save time.

Here is what you do. Measure the distance from the bottom of the crown to the top of the fork legs. Then remove the springs. Now measure the distance again. Subtract the second from the first, and there you have it, the total travel of your fork.

I'll try that route, when I have the $$$ in the bank awaiting the ordering of the new fork.

Thanks!

I'd guess that it's either 80 or 100mm travel. You could probably go up to 120 w/o any difficulties with the existing frame you have it on. A pic would be nice, or tell the brand of the fork maybe....

You assume way too much. It could be an old 63mm or even less. That plus if he puts a 120mm on a bike designed for a 80mm maximum he'll **** the handling up something awful. You can't just swap forks willy nilly.

Alright...don't laugh...

Link.

Mine is similar...the S-40.

It has a really strong frame/swingarm (7005 Aluminum), with a lifetime guarantee.

It's a starter that I'll eventually replace all the parts on.

By eyeballing the fork, I'd guess it's 80mm. How much bigger could I go?

Save your self a lot of money, time, and effort. A $300 full suspension bike from TARGET isn't worth sinking an extra nickel into much less replacing every part on it.
You'd be MUCH better served by saving your hard earned cash and going to a REAL Bike Shop (Which is somewhere were you can't buy dishes and Barbie dolls a few aisles away)
Go read the FAQ's posted at the top of the MTB section.

I read the FAQ before my 1st post. I understand the rationale behind it. Really I do.

There are no bike shops within 1.25 hours of here.

The Schwinn fits good. My wife wouldn't allow a $2k+ budget. I've had a 20 year hiatus from cycling. I used to have a $1200 Hutch ProRacer. I know what a quality bike is! Also, I still haven't finished my home theater yet. It's my main hobby. I still have 2, $2k subs to buy (have...lol). I want to slowly replace all the parts on the Schwinn, then once that's done, replace the frame with one with similar dimentions/fit.

There is a method to my madness. I just hope I don't continue to get snubbed for riding a Target bike. That's just ethicly wrong, & you'd end up running off a really helpful, funny guy.

That's more like it. Who says I can't give a $300 bike hell? I have fun on it. I've replaced parts so far: $85 pedals, $12 headset covers, $12 rear shock cover, $15 bar ends, $15 MTB rear brake pads, $25 cushy seat. Soon: fork, headset, stem, bars, grips. Then as/if it breaks...shifters, brakes & wheelset.

It's functional. I have fun. I get good exercise. I ENJOY buying new parts to fix it up...what's the problem?

Nobody said that. However, The quality of bike you bought at Target is far less than the same money would have bought at a real bike shop and you might as well know the truth

I'm not dogging you for how much you spent. Far from it. What I AM attacking is the where and what you spent it on. I could understand it if you were a poor college student, or a kid just getting into the sport with a gift bike, but you're an adult who's main hobby involves multiple $2000 subwoofers. If you were a tenth as serious about having fun and getting excercise as you are about your home theater you would have bought a bike from a quality manufactuer rather than a rebaged Pacific. The Schwinn of old is LONG GONE (bought out and turned to **** by Pacific) and the quality of what you find in X-Mart is sadly lacking.

Anything around 100mm should be fine. However buying a bike part by part is pretty much the most expensive way to go. It's only worth it if you are picky about what you like and would just end up swapping out loads of parts on a complete.

I'd recommend saving the money you would spend on upgrades then when you have enough buy a good complete bike, you will get more bang for your buck that way.

Unless you've seen the frame/swingarm, I'd say you ARE NOT competely correct in your bike snobbery.

But going this route makes things fine with the wifey. I am quite picky, but wasn't with my original purchase. Well sort of. Wifey was pointing out much lower quality bikes such as Mongoose & Next.

You'd be fine. 100mm could handle a 120mm fork.
