Well that the same suspension platform that i use on my bikes and it works bloody awesome aye!Yeah, I compressed the hell out of that avi so I could mail it. 2007 will do a better render than that....sort of.
The floating shock version (v2) uses a 9.5" shock and could get almost 9" of travel. There where clearance issues though, and I would have had to use a remote reservoir or raise the stand over. It just had too much mass and movement at crotch level..
Here is the most plausible version I think. I'll just use a pulley system at the pivot
83 - 150
9x3" shock
8" travel
no CNC work needed, but will have to have it for the weight reliefs.
good luck finding a damper/spring combo for that 53% rising rate
You mean approximately the same rate/curve that is used on a DHR/R9/El Cuervo/Giant DH/F5/anything else with a linkage? That's a much more organized curve than something like a V10 or a Sunday...good luck finding a damper/spring combo for that 53% rising rate
I have been playing around with a design much like that. The only difference is I am using a simple pulley to keep chain growth down and pedal feedback at 0. Something you might want to think about that I have done with my design is use a Split Pivot at the axle and have the rear brake mount on the lower linkage to get rid of brake jack. This way you can get rid of the floater and save weight. Good luck with it. I have to save up some more before I try to build mine.
Here:
if by approximate you mean ~20% to 30% for those mentioned bikes is about the same as 50% then yesYou mean approximately the same rate/curve that is used on a DHR/R9/El Cuervo/Giant DH/F5/anything else with a linkage? That's a much more organized curve than something like a V10 or a Sunday...
I do not understand this. As long as the brake is attached to a part that is also attached to the linkage then it influences the suspension while under braking forces would be my guess.Something you might want to think about that I have done with my design is use a Split Pivot at the axle and have the rear brake mount on the lower linkage to get rid of brake jack.

most manufacturers of rear damper units for mtb's suggest a rate change of no more than ~30% or else it's outside the effective damping range. just some extra cocktail party info: when designing around a fox dhx air the lev rate can't go under ~2.4, and also +/- 4% in the rate progressivity is considered constantGotcha. Don't normally look at it that way. I think the DHR's are still more similar to that one than you're thinking. Why would it be hard to find a damper that would handle that?

i think i would go with the dual sprocket if i was in your shoes, you will then need an eccentric bb to tighten the primary chain, but these can be purchased from phil wood online. you will then be able to adjust the BB height by adding/removing links in the chain.blong: Thanks, I'm at work.
FS: Yeah, the idea was concentric chain line, but I haven't worked out the top pulley situation. I could either use a dual sprocket and get no chain growth, or an Idler pulley/single chain system. The idler pulley system would be a little lighter and easier to implement, but I have about 3" of chain growth to deal with....good times.
