Tumbleweed Posted October 29, 2015 Posted October 29, 2015 The best thing about owning a Lefty, for me, was the fun things people say to you in start chutes...you know, like, "couldn't you afford the other side?", "does that make you ride in circles?", etc...there were timeless and tireless, and never failed to make me laugh heartily. Really.

Really. Yes, just like all the piano tuning jokes I hear - they get funnier every day.They say "What are you going to choon the piano?" "Howziiiiit piano"I say "Har har har, I have never heard that one before....."

Tumbleweed Posted October 29, 2015 Posted October 29, 2015 Must say though...I had two F-range Cannondales around the same time some years back: one with a Lefty and the other a Fatty. Both were pretty cool, but I preferred the latter.

raptor-22 Posted October 29, 2015 Posted October 29, 2015 What I always wanted to know is if anyone has ever thought of bolting two of them together and making a downhill fork. I mean if they are supposed to be so strong and stiff and smooth compared to a regular fork then just imagine how awesome 2 of them would be together?That's were the lefty originated, from the he headshok moto dh fork
cfcjim Posted October 29, 2015 Posted October 29, 2015 What about this? Hope he never comes across a left hand thread...

Specialized were dismayed to find during testing that their bikes converted to Lefties handled better than their own home grown suspension offerings. Initial discussions with Cannondale around licensing and manufacturing the Lefty for Specialized`s use fell through due to amongs others, cost, quality control concerns from Cannondale and Corporate pride.

Fisan Posted October 29, 2015 Posted October 29, 2015 A Lefty definitely does induce torsion in a bike frame compared to a normal fork. Unless bike and rider are weightless, there is no way that it couldn't. Not disputing the dual crown spreads the load a bit but overall there is still torsion. However, I can't recall hearing of any frame breakages caused by this effect. Maybe the stresses of normal riding are greater and frames are inherently strong enough anyway. Torsion is created by an eccentric load. As long as the wheel is centered below the headtube (thus no eccentric load) there should be no more torsion than a regular fork. Where the hub connects to the....fork rod shock you'll find some torsion. But the stiffness of the fork (double crowned + needle bearing tech) makes up for that "weak spot".

But the stiffness of the fork (double crowned + needle bearing tech) makes up for that "weak spot". yes there is torsion in the wall of the cantilevered axle of the Lefty. Its taken care of by being oversized. The rest of the torsion is absorbed in the 88 needle bearings and the square shaft that runs in them and the rest of the suspension structure. None of that is transfered to the bikes frame, at least not as torsion as far as I can ascertain. Would need to FEA the hole thing but my Pro/E license lapsed years ago!

Quality concerns from Cannondale.... Tell us what we know
Tumbleweed Posted October 29, 2015 Posted October 29, 2015 Cannondale were kinda the Specialized of the '90s and early- to mid-00s...
WIPEOUT 1000 Posted October 29, 2015 Posted October 29, 2015 I read somewhere that Canondale refer to Lefty as a strut. I do not own one, but there a couple of things I really like about them, e.g although they are round on the outside, their large diameter allows them to actually have a square leg and therefore run needle bearings compared to bushes on normal round legs. They are also a lot lighter than any normal fork.
raptor-22 Posted October 29, 2015 Posted October 29, 2015 Yeah I recall. They sponsored the xc series amongst other events. Earned a bad rep with the 3.0 and 2.8 road bike frames when they cracked at the rear drop outs. The article above seems to suggest Cannondale were concerned with qc at specialized and didn't trust that they could manufacture the fork reliably or with reliability. That's actually still true today as it's the only system Cannondale stillproduces in Bedford pennsylvania. Frames and road forks all come from China but lefty still made in the USA
