Hey there, question for you. I bought an 06 Reba from Speedgoat. I payed to have them convert it from 80mm to 100mm. When I took it in to my LBS (They couldn't find a Reba or I would have got it from them), they measured from the top of the seal to top of the crown. It was 4" exactly (the exposed section of the sliders). The mechanic said most forks usually have 1/2 to 1" extra on the measurements ( a 4" fork usually measures 4 1/2" to 5" on the sliders. Does this sound right? Do you think the conversion was actually done? What does your 80 or 100 measure? Sorry for the longwindedness.

I also bought a fork from Speed goat. It was an 05 that I got cheap from them and had them do the conversion. I had a similar concern. I even called them on it because I had another 05 reba with the conversion done and it was taller. Bottom line was it was done. However, there wasn't any air in the positive chamber when it was shipped, so the fork was sucked down a bit. When I called them about it not knowing this they told me that if I let air out of the negative chamber the fork would extend to its full travel position, OR I could put some air in the positive and it would extend as well. I let the air out and what do you know the fork raised up about 1/2 to 3/4 of an inch and was the same length as my other reba.

SO it was probably done...

Orbikbldr speaks the truth, I had the same dilema, same solution. Mine was shipped at 80, I did the conversion myself, so it I KNOW it was done, and I was still baffled, 2 minutes on the phone with SRAM, now I know. =:)

With the majority of 29" forks currently rigid or at 80mm, who's the first to start a 100mm forked bike gallery thread?

Not having read the manual or searched the archives first for the answer, is it pretty easy to make the swap from 80mm to 100mm? Do I need to buy new spacers, or is it just a matter of inverting the ones that might already be in the fork? I've got a new 06 and need it to be at 100mm.

All you need to do is take the spacers out, no need to buy new ones. If you follow directions to the "T", it aint that bad of a procedure. Took me about 45 minutes the first time, easily less than 20 if I do it again.

First - read the manual, do a search and then check Speedgoat's blog. It's easy if you're comfortable working on susser forks. It's a little more involved than a travel change on a Fox fork but not too bad.

If you have pulled any RocK Shox fork apart in the last few years, it's very straightforward, once upper and lower are separated, no need to even get into the damper leg, just pull the assembly out of the air side, and take off the black plastic c clip on the shaft, reassemble. If you have not pulled one apart, do as everyone else has said, and read the book! Cheers

Is there any oil spillage/replacement involved in this process?

Just a small amount of oil. You need to put 15cc into the bottom of each leg and a small amount in the top just for lube. Their is a service document on the SRAM website that show how to dismantle (and remantle?) the forks. They are at

http://www.sram.com/en/service/rockshox/view.php?catID=1&subcatID=8

Look at the service guides towards the bottom. I converted mine myself. Pretty easy if you follow the directions.

Edit: You don't have to pull the Motion Control damper apart to change the travel. Just remove the travel adjustment spacer. You do have to remove the fork lowers to get to it though. Its in the leg with the air caps, I think.

I agree with the above posts. I did mine last week and it took about 20 minutes to do the actual work....took longer to to the shop to get the small ammt of 15 weight oil that I needed to re-lube the upper and lower seals than it did to change the travel. The reba is so simple and works so well.After all the is done and tuned correctly (not even close to the RockShox recommendations) my Reba actually feels as good as my Fox Vanilla.

From what I found taking mine apart - all the above about length of the fork and positive/negaitve air pressure seems true.

That is where the spacer is, you are correct=:)

actually - you don't remove the lowers

actually you don't have to remove the lowers. Just let the air out, unscrew the top cap and the bottom nut (both left leg), push the entire air assembly up. Then pop the spacer out. Push everything back down again and add 10cc's of oil in the bottom and 5cc's in the top (both 15 wt) and screw the bottm nut and topcap back on. You are done.

Jay..

Yep..exactly so.. :)

The Reba is a great shock, easy to work on, and the performance is excellent....as long as you dis-regard the Rockshox set up instruction on the air volumes.

I'm currently running really low pressures in mine, and they work beautifully.. :)

What pressures are you running and how much do you weigh?
Thanks

Having just done it, and seeing your post, and thinking about it, that's HOT. Great idea=:)
