is 3.5'' better and why?
3'' vs 3.5'' shock stroke
- Thread starter freeriding
- Start date
longer stroke = moar shimz
and moar shimz always wins.
and moar shimz always wins.
I've heard that girth is moar important than length. A fatter shock that is a really tight fit in the frame will yield greater riding pleasure.

A longer stoke will generally yield a more progressive suspension curve.
uh, how so??
edit: that would mean my Foes DHS i just sold would be super progressive with its 4.5" stroke shock, yet its not

I've heard that for most popular riding position a strait shock is not the best option. They suggested I try one that is curved up. Too bad mine is more tap shaped so it forces me to ride with a more rearward weight bias.
Tap shaped shocks give an S shaped axle path dont they?
All 3.5" stoke bikes I've personally ridden (Devinci Wilson, Morewood Makulu, Intense m6) are on the progressive side of suspension curves. I'm going off of the popular 3.5" stroke bikes that are out there, not from an engineering standpoint.
In terms of mechanics, a longer stroke will always have a lower leverage ratio compared to a shorter stroke yielding the same amount of travel. Similarly a 2:1 ratio on a 3.5" will need less damping than a 3:1 on a 3".
its the bikes that are making it progressive, not the stroke of the shock.
3.5" stroke shocks fit 10.5" eye to eye frames.
3" stroke shocks fit 9.5" eye to eye frames.

My bike has only 2,7" shock stroke. Does that mean that I`ll never win world champs?
If it can't fit just use some lube and a hammer.
Don't bother thinking about suspension design, cause shock length is all that matters.
A 3.5" stroke shock will need a lighter weight spring... And if you are a light rider you may have big problems trying to find soft springs... Like 150-175 etc
I have a makulu I use a 200 pound spring and I weight 200 lbs
I have a makulu I use a 200 pound spring and I weight 200 lbs
Depending on what bike design a 3,5'' stroke shock is mounted with what leverage ratio,dh bikes with a low leverage ratio with a long 10,5'' shock & less travel like the Ghost,Morewood run suspension with a low spring rate.I have a session with a 3,5'' stroke with a 250lbs Ti spring rate but for me beeing light it's hard to find lower rates below 250lbs.
BOS makes steel springs in 187.5, 200, 225, 250.. and up to 375 lbs.
I was looking for info on this... Couldn't find much. tons of stuff on the M9 though.
So IS an M6 progressive? I've got one and I cant tell if it is shock setup or linkage. I'm a total hack with Susp setup.
UG.. Brain hurt trying to read... I know English isn't your first language so I'm not bashing here. I cant speak Norweigan so who am I to judge.
What I believe you are trying to say:
Depending on Suspension design, bikes with a low leverage ratio, long 10,5'' shock & less travel (like the Ghost,Morewood) run suspension with a low spring rate.

Exactly. A general rule is the lower the total ratio the lower the spring rate needed.
So an 8" bike with a 3.5" stroke shock (2.28 average) will use a spring rated lower than a 10" bike with a 3.5" shock (2.85 average), of course still depending on rider & gear weight.
What Carnaza was saying above and what UDI has said in the past is that for light weight riders it can be difficult to get springs RATED light enough for them if the ratio is too low (2.5 and below it would start becoming harder). For normal people this shouldn't be difficult
well i know you can order up a custom steel spring in spring shops that make them for cars and other stuff around here, you only need measures and the spring rate (i for example would need a 150lbs/in for a makulu, maybe even 125).
i believe you could get a custom made steel spring almost anywhere in the world relatively easily. i wouldn't know about the ti springs though. one thing that bothers me is that you can find a 400x3.5 ti spring that's good for over 120kg on a makulu yet i found nothing under 200 for lighter riders.
