Can I put a modern threaded suspension fork on a vintage bike without it choppering out? I measured my original fork and from fork ends to the top of the tube is 21 1/4 inches...do they make suspension forks that small? My head tube is freakishly long, like a girls bike, 7 1/2 " and the fork "legs" for lack of a better word are 14 inches. I guess that's small by today's standards. I would love a little spring up front but those monarchs are so expensive and I heard "schwinn style" forks don't work well for bigger guys.
is there a smaller suspension fork that won't chopper me out?
 
They make full suspension fork for little 12" Tonka bikes on up. 14" sounds like 24" tires ...............Curt
 
26"
I measured from the fork end to the crown and thought I got 14 inches but that was after a few PBR's so maybe I messed up the measurements. I do know that suspension forks are longer overall to provide for the "shocks".
I got a nice wheel with a disc brake rotor on it and i would like to get a fork that has disc brake bosses. Monarchs are expensive and I heard springer forks are flimsy. My co-op has a ton of MTB forks laying around so I was wondering if there are any that will work...I guess the easy answer would be "get off your lazy tokhas and go to the co-op and look"
 
1" head tube or 11/8". I just went out in the shop and you are right measured a couple and they are 14 to 141/2"

I think there would be a market for 1" here on the forum,seems to me there are hard to find and guys looking for them. To replace there old stock ones.............Curt
 
I see a lot of 1" and 1 1/8 thread less forks and I also see 1" and 1 1/8 thread less headsets. it looks like they are trying to attract the fixie crowd who want to put a carbon fork on an old fuji or whatever, I may be on to something. (No, I will not put a carbon fork on a MB)
 
If you come across a double crown fork, some of those can be lowered since the crowns clamp onto the fork legs. I know on my RST dual crown, I could slam it down a bit if I wanted to. Fork sag is a factor though as well, remember that when you are sitting on the bike, that fork will compress a bit from your weight, that'll be true on any sus fork.
 
Yeah, if you can find an RST brand one, they come in cheaper, I got mine in new condition on ebay for $25 + shipping last year. A couple folks around here have gotten them for about that price too, I know runnermike did. Just takes a little patience for a deal to come along.
