freaky ! , check this out

mono front fork , dunno how robust but looks radical

ride_whenever

It's only a lefty, i'm planning on putting one on my inbred shortly!

The Northern Monkey

lol.

missmarple

Ha, take a look in the "Your Rides" section, plenty of people with Cannondale Lefties!

Northwind

ZOMG, it has disk brakes too, like on a motorbike! Whatever will they think of next?

Now, this isn't new either... But it IS freaky.



I hear that after mating, it bites the head off the male bike.

As well as being freaky its bluddy ugly!

Dazzza

Meant to be quite good if not a bugger on the bushes, those whyte frames were about 10 years ago, i remember as i was tempted myself.

Iirc they commanded £1200 for the frame alone back then. :shock:

Back then nothing could touch them, not so much now mind......

Does anyone do a wishbone front suspension these days?

I should mention that I'm a roadie before asking the next question, but...

How do modern forks manage the non-axial loads? The wishbone solution seems like the obvious approach to me, but clearly a telescoping fork must have performance advantages, or it wouldn't have become the dominant technology (or you MTB types are all stupid ).

Northwind

Nah, it's the same as motorbikes, telescopics have their disadvantages but they're simple, and relatively light and cheap. Hossacks and telelevers and leading links and front swingarms and whatnot all have their advantages but usually bring with them other disadvanrages.

And also, they look silly.

joshtp

Err, lefty, yeah, RAD! um........
that white tho, very mad! suposed to be good tho..... my mate had one befor his 46. he said it was good but the creaking in the wet was a tad disconserting. also it has a sad name PRST4......imaginitive!

biff55

anyone got the balls to create a single sided rear mono fork bike and go for that " ducattti supersport look " ?
shit , theres some mad contraptions out there , make a good idea for a new post , craziest bike designs.

xtreem

biff55 watch this video, to see how robust the Lefty is. :shock:

Towards the end of the vid when he was hanging on the lefty, it looked like he was trying to shag it

I'd have a dabble.

You been hiding under a rock? These things have been about since Adam was a lad.

LOL, but quite true. they do do single sided rear swingarms, and you could put a lefty on so as to create a single sided bike!

not sure how robust/stiff the rear end is, but then again people said that about the lefty

cgarossi

My mate has a left on his cannondale prophet. I like them, quite futuristic, even though they have been around since the early 2000's.

pilsburypie

I went out for a meal last night and they gave me garlic bread.... GARLIC bread I tell you!

wouldnt you be tempted to design the fork so it was the other way around to match the swing arm??
hmmmmn, does look cool though!

Anonymous

I still, after all these years, fail to see why or how, the single sided lefty can be any better than using the same principles on a dual-legged fork.
Also, I love the way the guy in the video sayd he'd need a weight of about 500-700Kg to deform the fork, yet it visibly bends when he hangs on it.
He must be one super-dense fugger

supersonic

I think it works on the principle that one oversize pipe is stiffer than two smaller ones, for the same weight in piping.

But only in certain directions ;-). I imagine it is torsionally more flexy.

Anonymous

yeah, I get that, and have always wanted to build a smaller-diameter lefty style fork, AND a thinner-walled lefty style, but with two legs, and compare them to a "real" one.
However, I no longer have access to a machine shop.
I reckon having only one leg must throw up complications in all sorts of areas, such as hub mounting rigidity as well.
Don;t get me wrong, I'm not doubting for a second that the lefty works, but I fail to understand why use one leg. The re-inforcement to make ONE leg work, I am nearly convinced, must make it heavier than a less reinforced two-leg.

But, a normal fork would draw less attention, eh?

supersonic

It does indeed! People like the look of them.

They can be quite light, I have seen the XC versions well under 3lbs - but when you add in the gigantic hub needed it creeps back up.

It must be 'keyed' somewhere to stop the thing rotating!

ride_whenever

When i take my sids off i'll compare them to the lefty which i fixed this afternoon. Just need to make a new steerer now!

Anonymous

an XC fork under 3 lbs? I'd kind of expected them all to be in that range (excuse my stupidity, I'm neither a weight weenie, or an XC rider).
It's just, when Fox 36's can weigh about 4 3/4lbs, I expected XC forks to be much MUCH lighter.

The new sids are from about 3.2lbs. The Magura Durin is just below 3lbs for the lightest version, as is the Magura Durin race. Original SIDS were 2.6lbs, but flexed like a shatterproof ruler.

allthegearnoidea

Super, there not that stiff lol!

sadly then its was a pay off for the lack of weight!
is quite amusing for a heavy rider to have light forks as the sids! mucho flexyness!

ride_whenever

There really isn't noticeable flex in the new sids, pretty precise, even when pushing them rather hard.
