I think if Brittish media quotes an american, they should have to spell "tyre" with an "i" when they do it.And it's no surprise the tyre will never hit the back of the seat or the seat tube.
blast from the past - haven't seen your name around here in a long time! How's it going?genius
they probably didn't incorporate the tensioners into the frame to save money and leave open a deraileur optionno thanks. Concentric BB and no top tube? It'll ride like an Arrow DS3 but with flex between the fork and rear wheel. Boo to that. They're just trying to think of more ways to take people's money...and seriously, if they're designing a custom prototype, why couldn't they design a chain tensioner into the wheel mounts???
no.....that is the benefit of an ECCENTRIC bottom bracket.....concentric means the main pivot is concentric to( in other words revolving around) the bottom bracket.....one of the biggest benefits of a concentric is that you can run a single speed with no tensioner.
Lateral play should be taken care of by the pivot, since it it not dependent on the "lefty" shock for its support through the travel, just damping. Top out, can't speak there, you must of just ridden a crap batch of lefty's. I personally think the suspension quality should be fine, any lefty or headshock i've ridden (i ride a headshok for XC) hasn't been like vivid or top notch suspension quality, no, but good enough for that application.Finally, if it rides like any of the lefties I've been on, it'll always have a little lateral play and a little dead space at top out....hmmm....
Maybe better put at teh Number of links neded never changes, but on most any single speeds we have coming in, as the chain wears, we are having to adjust the tension Via either Horizontal dropouts, or eccentric BB. So you still need some way to adjust the chain tension.Sorry, my wording is off. Yes, you need a chain tensioner, but there's no chain growth. So, unlike with the more common single pivot designs, once you set your (chainstay length, eccentric position, chain length, etc) that chain length never changes, so you don't need a chain tensioning device as you would on any other suspension bike (except for URTs).
your just plain wrong... the HA wont change and the TT length will feel the same throughout the travel. because if you actually look at the bike the downtube is solid witht the bb and the headtube, so your effective TT length will stay constant. and that big gusset between the TT and DT at the headtube keeps the HA constant. your just wrong mansweet, a shrinking TT that slackens the HA.
