Another day with wheels (and so on).
Continuing from yesterday.
I'm disassembling a front wheel that had a Cannondale Lefty front hub and a Mavic CXP23 rim so I can use the parts for:
・Rim → 700C rim brake front wheel
・Hub → 650B disc brake front wheel
The hub is a Cannondale Lefty hub
32H, all #15 Campagnolo Rocco reverse Italian lacing.
Unlike the rear wheel, this is built considering disc brakes as a major factor.
I removed the quick-release mechanism from the right side of the hub and attached a jig for assembling Lefty wheels to check centering.
The rim is offset to the left side.
↑Left side (disc rotor bracket side)
By the way, there's a stripping mark from a flat-head screwdriver
↑Right side
↑Left side
↑Right side
The right side is slightly short, and the left side is way too short.
I had this cross my mind during the rear wheel too, but could it be...
It's not necessary to be next to the valve hole, but I removed one spoke from each side.
Yep, it's a lazy design with the same length on both sides.
Since the flange on the disc bracket side has a larger hole pitch, it seems they thought the spoke length could be balanced against the bracket offset with both sides the same length.
The rear hub had a reverse high-low flange, but with a disc front hub, the spoke dish from the freewheel body is so much larger that—just like with a hub with equal-diameter flanges—the anti-freewheel side actually needs longer spokes.
Built.
HB-R7000, 32H, all #14 Campagnolo Rocco Italian lacing with silver aluminum nipples.
Centered dead-on, shot from a slight distance to show off the Italian lacing
Spoke length is about this much.
This rim doesn't seem to have a directional orientation, but the sticker placed across from the valve hole to hide the rim seam has an icon indicating the technology used that faces only one direction, so I oriented it so it reads correctly when viewed from the right side of the wheel.
Going back in time to when I was done threading spokes through the hub, there's a stamping on the hub flange that says UI (September 2022)
The sticker on the hub body says UJ (October 2022).
Since I comes after U, it's not strange that the sticker was applied a month after the hub body was completed, once bearings and shafts and such were assembled to it.
↑Which is why this is a mystery.
The laser engraving on the hub body is MI (September 2014), but the sticker applied says MH (August 2014).
Maybe they had leftover MH stickers that they kept using even after September came around until they ran out.
