The Lefty Surrenders

by citybikemike • 62,174 views

After a spirited run down Madonna Mtn in San Luis Obispo, the Lefty fork on my Cannondale Jekyll finally called it quits

Damn I am tempted to change my fork as mine is the ultra fatty headshox. Yup thats the name But my fork is stll good except I have been treating my bike which is a hardtail like a free ride bike ... soon it will give way

I never said it sucks, and have remained faithful to the Lefty on my Jekyll for four years now. I haven't found anything at that weight that has the stiffness and compliance that the Lefty has.

@illbeda no actually some things are designed to last and there is not much that a untrained mechanic can do to maintain a lefty trust me I work in a cannondale retail shop. I actually see this happen quite often. Probably the most common problem with them to be honest.

its the other way around..The Lefty is an engineering marvel but looks very odd. I dare you to find me a lighter and stiffer fork than a lefty (price no object). FYI- some of our US fighter jets are using the lefty design landing gears (just food for the thought how durable a lefty can be).

But I ride mine fork through many terrains for 4 years and it's still fine

@ridersblock Sent it to Mendon Cyclesmith for repair, based on recommendations from the Cannondale forum on mtbr.

sorry, just admit the Lefty is a lefty design 4 years and it gives up? my last bike was running for 15 years and nothing "gave up". it's still fine and used occasionally. Lefty is just a pointless, unnatural design, made to look good but to work poorly typical all show no go

I heard the 2007 lefty speeds had assembly defects in them and they had the risk of coming apart. I bought a 2006 F800 with a lefty speed DLR 2 I guess I lucked out buying that one in November of 2006 instead of a 2007 model.

Sounds like the bearing races wore to the point where the needle bearing plated fell out. I'll bet if you replaced all the bearings and races, you would be back in biz. I would take it to a c'dale dealer who knows what they are doing.

thats somethin bad about the lefty

This is awful.I'm gonna have nightmares if my lefty being like this too.But I think the bearing inside must have glided away from it's original pad. D:

To all those that keep saying the lefty is a bad design please take the wheel off your car and tell me does it have a single strut and one sided axle. Um yes it does well there you go!! To many Internet know it all's out there!!

In colorado its well known lefties just dont last. Basicly the design is for racing / 1 season only. Thats why most people with out corporate sponsors just dont buy into them. Duable as sheet glas. And jack knife when they fail. #1 rule. Get ur forks as durable as you can afford. Dont do aluminum steerer tubes, use steele. Alum and cf is race only.

Scalpel is a Cross Country Race bike if you want a Trail Bike go for the new RZ120 or RZ140 Travel I rode a 2009 Rize 130 Carbon and it's fantastic get one fitted with a lefty and you wo'nt regret it

Just to add I'm on my first cannondale a prophet with a lefty max 140. Never owned one before but stripped it all the way down to parts with a few tools just waiting on the seal kit to rebuild it. It's an easy shock to work on imo and this is the first shock I have ever worked on!

As an update, my Lefty-equipped Jekyll just got me onto the podium @ Downieville :) I was gonna use my Ibis Mojo, but the Fox Talas on it broke...

Personal bikes are not race bikes. You should not ride a race bike as a daily driver. You should not use carbon fiber on daily or training bikes. I personaly would never use cf on any front end parts ever. Overbuilding a daily is great, just do it in a way it wont crack or fail

So a traditional fork has never failed? You know SFA about the Lefty design going by your comments Memphis

My next trail bike is gonna be a Lefty-equipped Cannondale Scalpel. I just really dig how well that fork works!

I just dropped a double-black grade rock garden and a high speed fireroad right before it failed too!

hahahhahahhahaa Lefty stink Rock Shox ! ! !

I tend to refer to mountain bikes as trail bikes - the Scalpel is gonna be my XC race bike for next season. If the RZ140 was available last year, I would have considered it. I picked up a Mojo instead - to say I'm happy with it would be an understatement :)

The Lefty is a cool design, but it's fundamentally flawed. Only one side of the wheel is attached to the rest of the bike, so every time the wheel hits a bump, it twists the fork leg. If it weren't for the needle bearings inside the fork, there is no way it could operate properly, and if a simple sliding interface needs bearings to slide smoothly, that is a sure sign something is wrong with the design. I think the Lefty cools cool as hell, but I'd never trust one to support my weight safely.

Did you maintain it regularly?You can break anything if its neglected.

Did you keep up with the servicing of the shock and cleaning and re greasing the bearings and resetting the bearings in the 4 yrs? I'm guessing not.
Report spam or abuse
the negative comments are obviously amateur riders and have not been the sport long enough to know how stiff, light and strong the lefty is.. Did I mention how well it performs on tight single tracks?
