BXT 24" build

It's childs play on 15 year old reba dual airs. The two I bought are about 120mm, but have a spacer to reduce it to 100mm. I 3d printer another spacer to shrink them to 80mm forks. Took $2 and 1 hour.

no way,  so you 3d printed a shorter spacer?  or is it a longer spacer?  would you be willing to make another and how much would you charge?  i was thinking it needed a whole new airshaft like the 29er rebas require.  could i

If you look at the pic, the stock hard rubber spacer is on the left, that shortens the fork 20mm. I added the middle spacer, that reduced the fork another 20mm.

I mean I could help you, if your air side is identical, no problem. You could save time and money and have a local library or maker space print one. I used PETG but I doubt it matters much.

These reba dual airs are pretty sweet. After reducing the length for a 24" bike, you can either shorten or remove the spacer, which I did so it's a 120mm fork for my kids 26" bike.

I never played with spacers but doesn’t that just affect the travel on the compressed side of the stroke, acting like a stop? What I was thinking was reducing the stroke length so that both lower and uppers could be shorter, to minimize the overall length and allowed a lower front end

It reduces the overall length. Rockshox sold the spacers years ago, it's a documented thing.

That’s a great, I didn’t realize that! Opens up things nicely then, off to find a good 26” fork then

Can the same be done on more modern 26 reba like the SL?

I have no clue. This was one clue a found a few years ago trying to understand. https://www.mtbr.com/threads/changing-travel-on-older-rockshox-reba-29-dual-air-fork.1075241/
