actually after reading the other guys posts i think i misunderstood pulleys, i beleive you guys are talking about tensioners, if thats the case i understand now,

 ha ha, refined DW, I like you! - its goal isn't quite the same as the DW though, but in essence it shares the similarity of having 4 pivot points along with many many bikes out there

 yeh, the new version I'm working on may not have split chainstays and the top links will be 1 piece too; there's gonna be lots of other refinements to stiffen things up. Also, the whole linkage has been lowered to so we're gonna try it without a pulley as there's less chain growth now

 ... yeh, I think pulleys may be in order! - or just a long cage mech

 approximately 16" effective seat-tube length, with a pretty short 45½" wheelbase and a bb height just below 14" - this model drawn will be the 6ft peoples version (small/medium), I'm gonna work on a larger geometry for bigger riders with the new version too.

h'tube angle is 65º, I kinda refined the geometry to be better suited to handling well in techy or steeper dh courses, but so it will still perform good on fast and flowy courses too

 a certain symbol doesn't work on this website - its the sub-6ft peoples version
