Hi all. I have a specialized FSR frame and have a set of 130mm Fox forks spare. Will they be ok on the frame as it comes with 100mm standard or too much travel. Are the frames designed for optimum travel etc.
Thanks
What yr is the frame? I have a 2001 Stumpjumper FSR that originally came with Judys on the front with 100mm travel.
In Spain last yr I borrowed some Marzocchi 130mm forks as mine died and it handled like a dog on the flat or anything going slightly up.
I've now got Rebas that are adjustable from 85-115mm. They are much better, but I still turn the front down a bit for long climbs. I don't know what the axle/crown length on the Marzocchi's was, but I suspect it was quite a lot.
I ran 120mm Marzochi's on an 04 100mm Stumjumper and it worked really well, and the Marzochi's are very long for their given travel too, however they had lockdown and that helped ont the steep climbs...
As suggested you need to know the axle to crown length of your old forks and the Fox forks to predict how much the handling will be affected, you can run a bit of extra sag on the longer forks, but your still might find the ups a problem.
Mind you if you got them anyhow, just fit them go for a ride and find out!!
