Benefits Cannondale Lefty fork by Beukers Bike Centre

[Lexmauler]

why rebound of compared one is so weird? maybe because of lack of air in airspring?

[AalexX136]

I am curious as to what fork is being compared to the lefty

[tuckfield656]

they are still funky looking, so i will probably never buy...

[004nation]

I want cannondale to make a heavier 160mm+ travel version of the lefty. I suspect it could make a stout freeride fork if it was beefed up a little.

[maitreMechant0]

dont compair dh bouble crown fork whit xc lefty fork they are not made for the same practice.... compair 110mm whit an orther 110 fork....

[maitakivore]

empiricism FAIL

[SquashysDaddy]

Double crown lefty maybe stiffer, but why do all the 2012 Jekyll's have conventional forks?

[maitreMechant0]

@SquashysDaddy becose jekylls ave 150mm travel.... lefty fork travel is from 80mm to 140mm so lefty are not perfect fit  but sometime people put lefty on their jekyll and it's run good

[illbeda]

They are trick,no doubt about it,i love the look,the engineering,and the ease of removing the wheel,etc,etc,etc.

I wonder why Motocross bikes havent adapted this style.I guess when the Patent runs out you will see them on Honda's and stuff.

[davniels]

I just love my Lefty!

[artrbinfo]

The regular fork is flexing, because it's single crown, while theirs is dual crown. Please compare boxxer to this fork, and then let's look who's got more lateral give/flex!!!

[mtbsieppo]

@artrbinfo And when they would mention that the Lefty is almost 4 lbs lighter than a Boxxer you would tell them to compare it to a regular xc fork, right? And just for the record, the lefty is stiffer 'cause of the square shaped tubes, not just for the dual crown structure. Congrats for missing the whole point of the vid...

[artrbinfo]

@mtbsieppo Lefty 4 lbs lighter then Boxxer? rofl Boxxer weights exactly: 5.98 lbs and Lefty weight 3.01 lbs (1365g), so the difference is 2.97 lbs not 4. And lets not talk about weight distribution :D Square shaped tube intube, will always have high drag on twisting, and will lock-up suspension as easy rounded tube. I have ridden the DLRs and they are nothing compared to Boxxer or even a Bomber for Freeride or DH. So keep jumping with tiny DJs or go back to sauna to drink some more! Paskat :D

[mtbsieppo]

@artrbinfo Haha, the end of your post was actually pretty damn funny, in a good way! However, when talking about the weight of Boxxers we both were kinda right, as there are 3 versions of them heaviest one being 6.63 lbs. My point was though that it would make no sence to compare a lefty to a Boxxer as they are designed for completely different kinds of riding. Comparing a Lefty to another xc fork, on the other hand, is fair.

[artrbinfo]

@mtbsieppo I see your point. Still I see that double crown at this given vid is the thing that changes the flex the most, while as you said that if compared to other xc, Lefty is the only one with double crown I've seen, you know... Anyways, sorry for my "passionate" reply before. I'm a fan on Finland btw, I have few friends there, and last year I rode DH at Ruka mountain. :P Nice 180s in your video. I tried DJs years ago and they are freaking unforgiving on mistakes, unlike freeride bikes!!!

@artrbinfo It's all cool, I was being kinda annoying myself too so sorry for that :) I think it's time to go ride now!

[torentmonkey]

Tough is stiffer my moral gets sooo low when riding a lefty, it's just not the way i know its safe riding with half fork.

[usnmustanger]

@kyligz : I am a mechanical engineer and a mountain biker, and I can tell you beyond a shadow of a doubt that in any moderately spirited trail or XC riding, these forces are exactly what the front suspension system will experience. I know you said you "wont [sic] bother explaining all the principal errors," but please, enlighten us with your vast knowledge of engineering, statics, dynamics, and materials.

[Royalty46]

I own 2 cannondales. 1 with a Lefty and the other one with a fatty. The fatty flexes noticeably more than the lefty. I just luve the Lefty :) I guess you got to ride it a few times, to believe it.

[motanelteo]

..yeah right .... and every 200km you have to fix"it NOT GOD ( sorry for my english )

[bedevere007]

nice



[manokaiser]

These are the kind of forces you get when you turn AND hit a bump. It's a combination of gyroscopic and lateral forces. You don't need to analyse it to that level though to feel the difference. You just have to go out and ride a lefty. Then let us know how it feels to you.

[Shegal1535]

The science there is flawed...but the inherent rigidity, and strength (regardless of load direction) is apparent. It's like a landing gear on a bicycle. I'd lik eto see lefty "tested" against a triple clamp fork like the old DH MOTO 120s or a Maverick Duc32, i would assume that triple clamp forks are the strongest because motorcycles use them. Haven't ridden a lefty..but i'm coming around...slowly.

[bbboomer1983]

@Shegal1535 Its not a downhill or freeride fork!!! So testing a lefty against a dh moto 120s is pointless becaus they are made for different usage.. but your question made me wonder and it would be intresting how they compare to eachother.... btw it is a nice fork last month i bought myself a cannondale rz onetwenty 1 and its just so comfy to ride :) the fork make's some noise becaus of the roller bearings but its aloth smoother then my older rock shox reba race

[Shegal1535]

@bbboomer1983 I ride a local Full frame trials league on my '98 "Uber" V with the DH moto 120s up front

The biggest problem we see is with forks giving up, giving out, giving way, and in general not doing their job there arent many forks that can handle being leaned on while balancing or humping a 200# rider and his 30# bike round. I've seen Duc32s twisted in their stanchions to the point of explosion, rock shocks snap so far Fatty's hold up. We're just wondering if the lefty is the deal!?

[bbboomer1983]

@Shegal1535 hmmm hope someone can do a video testing that

[motosportjunkie]

I agree with kyligz, there will not be 5-10 pounds of sideways force on my rim or fork at any given time, even in the sharpest of turns.

[arouil1]

I ride a Lefty on my Cannondale and it is amazing. So good that I don't want to go back to the old style of fork.

[kyligz]

lol this video is so wrong.

I wont bother explaining all the principal errors but let me just say it is impossible to get those forces on a fork when riding.

[tlldrkhndsm]

@kyligz

??? Do you mountain bike? Not, sure why you think that lateral forces are "impossible" to experience while riding. Care to elaborate?

[duder215]

@kyligz What type of riding do you do? Have you ever cornered or turned at a switched back??

if you are just riding flat fire roads than its impossible to get almmost any force lol

[samvegg]

@kyligz pfft!!, my broken front wheel can explain why those forces apply when turning

[tlamadrtic]

test like in a fckin teleshoping :-D

[MrRyanv09]

interesting...may have to give c'dale 29er's a serious looksie
