Could very much be interested in this. Have a front QR disc hub in my parts bin that I haven’t had a good reason to build a wheel around.
That Carver is pretty perfect too.
I’ll need to check. I know if has magnesium legs but that’s all.
160mm of tube. Let me know. It came in a frame deal and I didn’t see myself using it
And fwiw I have multiple carver forks and a handlebar and really like all of them
was def installed and ridden

I finally dithered all the steerer and headset parts to get this assembled, which was a game of tenths of millimeters
The Lefty Olaf fork I bought last year on eBay while drunk is the smallest “97mm” nominal headtube spacing size (100mm actual) for Cannondale’s non-preloaded 1.5" radial headset bearings, and the smallest available ZS44/ZS56 headtube was also 100mm tall.
Marino didn’t want to participate in this dither themselves so I cut ~4mm off the headtube afterwards, from the top only because R&E only had a facing cutter big enough for 44mm. Taking this much off means the upper headset cup is bottomed out on a shelf inside the headtube.
- Alex CNCed a ~1.5" OD aluminum headset spacer to preload the angular-contact headset through the fork’s upper crown, with a slit cut in it to clamp the 1.125" steerer through it
- https://canecreek.com/product/hellbender-70-slam/ which recesses the bearing down into the cup, with just the split ring and no topcap, giving me negative stack height for part (1) to nest internally
- zs56 headset lower part | headsets | core | products | acros sport GmbH was the thinnest lower cup and crown race available
- Black Tapered Steerer Tube 1-1/2 - 1-1/8 For Fox 32 34 36 38 Rockshox Forks | eBay is just big enough to fit the fork’s lower clamp after removing the knurling in the lathe, and still cut a slight step for the crown race
If I had still needed more room, the next moves would’ve been to remove the external part of the upper cup to make it effectively an IS41drop-in style, then to either fuck around with thinner steel crown races or recess the lower cup too. If I really like this shenanigan I’ll hoard another fork in the biggest 122mm nominal spacing for the next frame to have less of a challenge.

Amazing. I see the pro logo on the stem, but what model? And what bars are those?

I think this stem was discontinued awhile ago
The current placeholder handlebars are VO Seine
I’m going to build it up with XT 1x12 flat bar controls first, but may redo the cockpit with dirt drops and the new mtb-pull GRX levers if that can work

I’m making a low trail rando forester bikepacking bike here
This fork has 60mm of rake and is also upside down to be able to support a front rack as suspended weight, which would be perfect for portaging a chainsaw
(and impossible to ever put a dynamo hub on)

wait wat pull?
ok i want to see the front rack you come up with for a lefty fork
cable pull of 12-speed GRX isn’t any different than shimano road/gravel-11 but they’ll sell you a derailleur for it that’ll clear a 10-51 cassette, so you can make the 1x12 “MTB” drivetrain of your dreams on drop bars with no faffing around with modifying junk. I’ve also been noodling about sticking dirt drops on a full-squish bike…

ahh instead of it being a different right lever ratchet, they modified a MTB dangler for Road cable pull and added a barrel adjuster there
costs $150 instead of $75 for an XT dangler, but that feels worth it to not be hunting down a special lever version or thinking about where to put the barrel adjuster

SRAM switched pulls in a recent group but yeah that GRX RD solved a lot of mullet drivetrains.

their trike hubs don’t work for this at all — the bearing and stator inner diameters are way too small, and the axles are integral to the hub instead of the fork
more plausible would be modifications to the new SON 29 S hub shown at eurobike

Cmon man you’ve already enlisted Alex, let’s take this dither all the way and swap the lefty axle for a trike hub receiver
oh there are so many other dithers tho
like mounting my 300 lux ebike light IQ-XL E Highbeam - Busch + Müller EN on a biaxial servo gimbal LEVAL - Busch + Müller EN powered by a USB-C battery using a 15V PD cable
looks like they just announced a more expensive fully integrated one that uses software to do the beam shaping instead of repositioning the whole headlight mount mechanically with a servo Digital curve light - Busch + Müller EN
