How can this bike use a 300 spring for a 175 pound rider?? Does the lower link/shockmount affect the leverage?
Bike looks wery nice btw.

3" stroke shock for 8" of travel is a pretty low leverage ratio... 2.67:1.Espen said:

Acadian, your custom title changed!
Espen, you're running a Romic, right (Turner DHR?)... Spring rates run a little lower with the 5th Elements anyway.

How you like riding that hardtail?
Seriously, I'm 165 and use a 350. You might want to try out at least a 400.
Kidwoo and Kid-deux both say so.
The dw-link system imparts so little force on the rear suspension under acceleration, that the spring's only job is to soak up the bumps. You don't need a heavier spring or extra compression damping to keep the suspension from bobbing or compressing under acceleration. I am 165# and I am running a 300# spring, but will switch it out for a 275# spring when we get them.Espen said:

As someone who was horribly oversized (6'3, 220#) for how dw has his bike set up, I must say that thing pedals great. I snagged a quick parking lot test at Mudshoe and once it settled into it's sweet spot, it didnt feel like the rear end budged when I stood up and pedaled hard. Nice work, now where can I get one?
and you know that that means...kidwoo said:Kidwoo and Kid-deux both say so.
we can lock this thread now! :devil:
I did some pedaling around on one...its unreal.
Let's face it, any bike can pedal "perfect" if setup with enough pressure in the SPV...
The crazy part about this was dw had the minimum in the SPV and it was like a hardtail...i tried to pedal squares...it's cheating.
Ska Todd...this should probably be a PM, but how exactly should we get in touch with you about becoming a dealer. (Bikesource)
Thanks man!

If it pedals so well on its own, why is it specced with an SPV shock? Wouldn't there be greater advantage in having a more supple, sensitive shock (even a Fox) instead of a 5th?dw said:
SPV shocks allow 10x the tunability of a Fox. Not to mention, with a spring that light, I can't figure that a Fox would be that much more sensitive...thaflyinfatman said:
I dunno, pedalling well or not there is a whole lot to be said for SPV shocks beyond the "platform".
edit: come to think of it, IH probably also gets a deal on bulk quantities of Progressive shocks, but I still stand by my above comments
hey. where can you get such light springs for 5ths in long strokes. i look on progressives site and it lists 350# as the lowest for the 2.75 stroke. id love to get a 275 or 300.ska todd said:
The tunability of the 5th Element CV/T shocks is awesome, and Progressive provides race support at the NORBA and World Cup events for Sam Hill, Bryn Atkinson, and Mathieu Laurin. We use the 5th element shocks in the same manner that the off road guys use them, for big hit bump absorption in the end of the bike's travel. My personal dw-link DH prototype is running about 50-60 lbs of pressure in the chamber, and it is really REALLY supple over the small stuff, but that's a calling card of dw-link bikes, so it wouldnt be right if it didnt! Like you guessed though, one of the great things about the new bikes is that they still pedal and perform ridiculously well with the Avalanche, FOX, and Romic shocks.thaflyinfatman said:

So it would be possible to maintain ride quality even while running a ROMIC rear shock? I am only asking b/c I already have a couple and have been very pleased with their performance.
That sounds pretty cool. I also run 50-60psi in the Swinger on my SGS, but it's still not very supple unfortunately. I look forward to trying one of these new beasts!dw said:
When will this thread include questions about the freeride version that Todd was riding at Mt. Creek last weekend 
It has curved tube for more stand over height but besides that it of course pretty much looks like the DH version.
It has curved tube for more stand over height but besides that it of course pretty much looks like the DH version.The bikes can fit a Michelin 2.8 with 10mm of clearance all around at the Chainstay yoke, and much more everywhere else. That is a lot of clearance.klunky said:
The bikes were raced to the Pro Men's podium in the 2 muddiest races of the year so far. (actually, the bikes have made every single pro mens NORBA and WorldCup podium so far this season)
Even in that crazy WV mud I didnt have any mud issues with my proto.
Dave
Back off on your begining travel compression adjustment. You can go all most all the way out. MAX I would run is 1.5 turns in on an SGS. At 50-60 lbs, your SGS should be reasonably supple, not like the DW bike, but pretty damn good for a horst link bike. FYI, the Iron Horse team guys ran their shocks at 90-110 lbs on the SGS last year and the bikes hooked up nice. Also, make sure you are not running anything like 40 PSI in your rear tire, because thats going to screw things up too. Start at 24 and work from there.thaflyinfatman said:
Hope this helps!
Dave
PHEW- i thought i was the odd man out reading all the above shock setups, but that makes me feel a bit better. I set up my 5th with 110 and feels good to medw said:
hehe.....gordo is wacko
I'll try that, thanks!dw said:
Also, 40psi? Have you been talking to Acadian? :nuts:
until you told me I didn't even know a DH tire could hold 80psithaflyinfatman said:
Actually, I am 180 pounds (without gear). I weighted even more a couple of monts back. The 450 feels good now. I got 35% sag.

ahahaha... the highest I ever run DH tyres is 60psi, and that's only in "extenuating circumstances"Acadian said:until you told me I didn't even know a DH tire could hold 80psi
so whats going on in that picture i quoted?dw said:
http://www.littermag.com/OLS109/pages/so13.jpg
it looks like the tyre is almost touching the bar joining the seat and chainstay? or is it just a funny camera angle?
Im not bashing the product infact im sure im going to get one!
just a crazy camera trick I guess! The two support struts (in front of the tire in the pic) actually are next to the tire spaced very wide apart. Theres a lot of room between them and the tire. Also, thats a picture of an alpha prototype frame. The beta prototype/ pre production frames are quite different looking.
