That's our proposal for ww hubs. We have decided go for the most complex at once, and produce our first batch of protos below 300gr the set.

BCB Rolling Stones

Front (lefty version)
Body: Aluminium 7075 T6, color anodized, laser etched
Hybrid bearings: 1 x 61805 2RS / 1 x 61902 2RS
Cap: Anodized aluminium 7075 T6
Bolt: Ti6Al4V

Same hub is possible to use as lefty hub or QR with extra axle added.

Rear
Body: Aluminium 7075 T6, color anodized, laser etched
Hybrid bearings: 2 x 61902 2RS / 2 x 61802 2RS
Cassette body: Anodized aluminium 7075 T6
Mechanism: 4 pawls and ratchet, quenched and tempered steel
Axle: Anodized aluminium 7075 T6, variable section, treaded ends for caps.
Caps: Alnodized auminium 7075 T6

The weight for the set is for this first testing version, some more coments:

1. Teh pictures show the weight for the set lacking two hybrid bearings, so normals full stel ones are assembled there ;-)
2. Right now, we are working on UD Carbon axles
3. We want to test also some special ultralight caps using high performance polymers
4. We have detected some areas in the hub bodies where we can shave some more grams.

These, together with some more ideas will allow us to offer a final lighter version...

Now is time to "burn them" in the tracks, be tuned!!

Happy New Year.

Looks great, what will be the price of the Hubset?
And you are using standaard Hope Pro2/Pro3 cassette body and mechanism?

WOW, looks great (flanges like the Rockman Trial disc hub) and the weight is sweet.
Are there also planned QR front hubs ?
Do you need test rider in muddy german conditions ?

Good idea :thumbsup: Love multifunctional parts.

I guess I have found few gramms.
Please see red marks at the attached pic. Most hubs I know are machined or drilled at the flanges between the disc mounts. May yours in a little while too ;)

See also the Rockman hub. They save a lot weight by leaving meat. And this trial hub works well on MTB. I ride it nearly for a year at my racebike (with ZTR Race and DT Revo 1,8-1,5)

Yep, we have considered that, and actually we will machine and "eat some meat" doing such windows in the production version, with a samll difference, we will avoid to open them totally, so a thin skin or web will close them, as a compromise between weight and stiffness...

Pretty sure the magazine or band will be contacting you about the name.
:lol: :lol: :band: :lol: :lol:

A couple other suggestions for names:

Apple iPhone

Coca Cola

Toyota Camry

or maybe even Cap'n Crunch.

Cool hubs though...
