So is the FSR stuff holding up to the DWLink well? Does it really feel that plush over square edge bumps?
The short dual link bikes have been around along time , the v.pp, maestro , Marin's quad link, BMC's APS series, karpiel's disco, schwinn rocket 88, the DW link------the system is a 4 bar and it can work well.
So this is not new , some of the iron horse bikes had to steep of a progressive rate twards the mid and end of stroke and were harsh , but you could valve a shock around it .
The Pivot is stiff and harsh if you do not run the large can on the shock, and have a plush tune on the shock , The turner as well ----( I could easily bottom the 5 spot badly , and the sweet spot was in the middle ring , not the small ring )-----this works well untill you start slaming on the bike and then you can have a bottoming problem you need to solve for.
So the DSL 4 bar , and or the Horst link 4 bar do all work , The tune of the shock is major importaint on how plush the bike will be and its resistance to bottoming.
Either set up will work without the PP on , and be plush over squair edge bumps , the anti squat works on either set up and is greater in the small ring where its needed most, the movement of the instant center migration is similar.--( the HL bike had a wider sweet spot in more gears than the DW 5 spot )
The big problem with the DSL bikes is the sweet spot is easily missed unless you have a set sag , the horst link is way more forgiving and the sweet spot is there through a wider range of ride heights no matter what the sag .
All this stuff is not new , and the HL has been around longer and really does work nicley, Dave is getting the DW better all the time too.
I really like Dave's newer DELTA system on the Evil Revolt , this will be one of his best designs of all.
