Fixed Super Light Super Safe

Oy - weenies. I need a new saddle.

My current all crabon Farsports job / dodgy second from an unnamed factory in China appears to have a bonding problem between the rail & nose.

Sub 150g is your target.

Hovis said it with his SLR recommendation. Solidly built, cheapish, 135g, and ,for me, super comfy.

If you have more monies a Tune speedneedle. I'd love one of them.

Like Mr Tester, SF etc I think the larger bearings of the lefty will make a stronger hub. I have my doubts that the complete hub assembly will be lighter due to the larger axle diameter (even if it is stepped). Just a suggestion outside of the local engineering firm / job shop whom would need a drawing to manufacture an axle, it may be worth contacting

or SF's contact whom have custom manufacuting experience with Lefty.

The only other suggestion I have, remembering I'm not 100% familiar with MTB equipment so I'm throwing this into the arena for taking apart, is to use a bolt through front hub which would mean (if my thinking is correct) machining a simple stepped and threaded shaft.

My contact just rebuilds the forks, hes not machining axles AFAIK.
The alu clamps he designed and had made are very nice. But like I said he did'nt make them.

Don't use Ti for this one, it will be hugely expensive and heavier than aluminium. I only used Ti because I was already constrained to using 10mm axles, but anything over about 15mm can be done in aluminium alloy with plenty of strength. 7075T6 alloy bar is about 1/10 the price of 6Al4V Ti of the same dimensions.

Defo aluminium. But are you thinking of standard threaded ends for lock nuts, and track nuts. Doesnt sound like a good place for aluminium threading.
