I have an old Cannondale lefty bike and I’m switching over to a Cotic simple frame to go singlespeed, but want to switch over my lefty fork too.

I’ve seen a couple of pics of Cotic Simple frames with lefty, I know ChunkyMTB had one, so would love to hear from him.

How will it fit, do I need a headset adaptor of some sort?
All advice welcome.

Thanks

Cannondale Lefty-4-All 11/8" Steerer KH075

I’ve given Chunky a nudge to wake him out of his bear pit. He’ll be along shortly…

It’s super easy. My Simple was a medium so not sure what difference the headtube length is on them. Most Lefty’s you can’t alter the clamps.

I ran a standard Hope Headset. You need the Lefty steerer adapter (I think I may still have the one I used for my Simple at home – you’re more than welcome to buy it off me if I do.)

My advice is to measure the gap between the clamps of your Lefty, let me know what they are and I can check the Lefty I used on my Simple.

Damn you for sparking my Lefty lust again…

I’ve moved onto Clown Wheels…

Chunky, that’s a great offer.
My Cotic frame due to arrive any day, will measure my current Lefty stuff and the Cotic frame when it gets here and get back to you with measurements and hopefully if you still have your adapter, and it will work – we an do business!

Thanks.

Ran one on mine for a bit (older model 1 1/8 headtube not tapered) using a project123 adaptor, just as easy to fit as any other frok.

Mine is a 16in/Small and the headtube length is fine, works ok on a medium as well, but never tried anything bigger, there is a headtube range they work with, can’t rememebr fof the top of my head but 130mm total stack height is ringing bells…

As chunky said, most of the never leftys have bonded clamps so you can’t alter the height, the older DLR, Jake, and Lefty Max 130 and 140s had separate clamps so there is more adjustment available.

@ChunkyMTB Already on clown wheels, Thus the transfer may be logical, if expensive. Did you get a new Lefty and convert over?

Still have proper wheel size for proper riding 🙂

Counting the sleeps…

My Cotic frame due to arrive any day

One of the 29er ones then? Post some pics up when you get it – don’t seem to be many about?

I got a Carbon Lefty off the classifieds on here, basically brand new for peanuts. It’s a 110mm so added two 10mm spacers (5 min job). Checked clearance and all good.

It’s super plush.

The first thing to check is total stach height of HT and headset.

If its a new 29er simple then go for a hope internal lower cup for 1 1/8” forks.

This helps compensate for the slightly higher bar conversion.

The Lefty for All kits are a piece of cake to use and install even if you do need three paist of hands.

Gratuitous Skookum Lefty shots:

Might seem a silly question, but how are you fine tuning the space between (bonded) clamps with these conversions?
My Lefty is a damned tight fit with a std c’dale frame and the headset/top spacer

Musing over the idea of converting my Lefty Max 140 to a 29er.

Ok, watching the installation of the 321 project conversion kit, it makes perfect sense know, can anyone confirm the lefty for all, is the same setup? (I’d doubt it would be different)

Yes, very similar if not the same.

You can kind of just see the spacer (in the clamp) of mine.

These come in different heights according to the sapce they are needed to fill.

Essentially I had 6mm to play with/fill.

5 of that is the carbon spacer a the 1 is the aforementioned space in the clamp.

Hope that makes sense!

a closer look

Did the same thing on my Love/Hate..

Love it!

Go on… ❓

Loving this 😆 now I want to build a Soul Lefty, no other reason than they look so good.

Every so often I get Lefty lust, before the rational part of my brain kicks in and quietens everything down…

Want!

Go on…

26″ bike with riser, 29″ with flatbar…

You new to the sport?…

I was more referring to the discipline the product was designed for rather than the wheel size. 😆

Loving the look of a lefty on a skinny frame.

I can honestly say that this was no inspiration behind my conversion….

….. none what so ever.

Ah, ok.

Sorry to kick start this topic again, but a slight delay on finding a frame, my options now ate…
Cotic soul (which has a tapered head tube)
Or
A secondhand Sanderson Life with whatever headset that has
…and having looked at the project321 site I’m still unsure what I need.
I have an old ‘clamp on 100mm Lefty
I’m thinking what Chunky has may work, if you’re still out their and if you agree, we could do business?
