I was finally told I could release this info to the public, so here it is.

The rear Alchemy hub is in the final stage, I was told unless something goes massively wrong this the last prototype before production. The weight is around 210g, it still has a titanium freehub body, the axle diameter is 20mm, it is now a high low flange design and it will have a bearing preload adjustment. There is a massive bearing between the drive side flange and the freehub body and then another one between the freehub body and axle. There are no micro sized or thin section bearings in the hub.



Edge has revamped there line of rims. The first one is the 38 is gone, it is now a 45mm rim. The 45 was designed to be as aero as possible and has been windtunell tested, I will see if I can get some of the data but I can't guarantee it. The weight of the 45 tubular is 300g and the clincher is 410g. The shape is now the same as the 68 so mixing a 45 front and 68 rear will not look add as would have with a 38 and 68 because of the different shapes.

The 24 has been discontined and is now being called the 25. It is jost over 25mm tall and now has a semi aero shape to it. The change in the shape of the rim is also allowing them to make a clincher version of it. The tubulars are still the same weight and will start rolling out in about 2 weeks from now. The clincher will be launched much later, I was told at least March and maybe even May.

The 68 is not being changed but is finally being called what it truly is and that is the 65.

The 118mm rim that they were working has been tested in the tunnel and it did not do as well as expected. I was told they would be making changes to make it faster and there is no expected availability date because of the work that still needs to be done.

The 2.0 rims are now the same price as the 1.0 rims. The 2.0 and 1.0 rims are the same rim with a extra layer of carbon added to the 2.0 for extra strength. They have always been that way and if you got 2.0 rims last year at the lower price you get a deal.

I will have some 45's next week and will post some pictures and I am told I should have a pair of 25's in about 2 weeks and will post those when I get them.

The hub looks great, 10g lighter than the DT240S rear.

As for the Edge rims, some changes there. I'm surprised at the weights, they are now looking a little bit heavier than the Reynolds DV46ULs, not the leap forward I was hoping for from this innovative company but still great.

Thanks for the update Troy!

I wonder how much the 25mm clincher rim will weigh. Its making me very interested..

I now wish I didn't buy a DT240 rear hub now that the Alchemy will be out by the time i decide on what rims to build up.

Please keep us updated

Nice looking bit of kit you got there.
It doesn't look dissimilair to the Goldtech hub.
Are there plans to offer it with a 2:1 drilling?
Good to see you back here too.
Cheers, Rob.

Awesome Troy!! keep up the good work.

That is true but the Reynolds UL rims are much higher priced then the Edge rims. The DV UL's are $1000 a rim at retail and the Edge are $750.



Yes, there will be a 2:1 version. Jeremy is planning on one and then I am planning on one that will be slightly different from the one Jeremy will sell.

45mm...sounds perfect!
2.45

What about Alchemy hubs? price? durability? "Stiffnes" (VS DT240)?

I'd like to try a couple of hubsets when they are ready please!

Cheers.

Can't weight for the rear hub....

Front hub is great stuff. Have several wheel build with the front ... not as light as some others, but light enough for me.... If the Rear will be 210gr a pair will weigh 270gram... Most rear hubs alone weigh more then that.

If they want to make a truly aerodynamic 118mm deep rim, they'll have to pay royalty fees. I don't think their is anyway to get around the fact that a rim that deep will stall out at fairly low angles without curved sidewalls.

The other option, is a fairing based wheel like Mavic has in the Carbones because as the Hed/Zipp patent doesn't apply to fairings. This option, with their 25mm rims would make for a fairly light wheel I'm guessing. However, the drilling options for custom wheel makers would be a nightmare.

Thanks for the info.

Do you happen to know anything about the disc and seatpost they mention in their catalouge?

how do these compare to your hubs? You also have PM.

ahh, that’s the freehub design that bikemesenger’s been talking about.

if you talk to troy enough, he’ll eventually mention the freehub design that he has thought up, but hasn’t gotten around to building.

i get it. i like it.

also explains why it needs such a fat (stiff) axle.

(notice the giant orange bearing in the bottom photo, and in his description)

are there any issues with the bearings carrying a static (instead of rotating) load?

(at any given time, only three of the four bearing are spinning, at least if i am imagining the insides correctly)


also, how much will it cost? just a guess.

i want one, 2:1.

Everything about this rear hub is made to be as stiff and long lasting as possible. The price will be a bit higher then a Dt 240 but it is better in all aspects as far as I am concerned.



I don't have any info about the disc but I have held a seatpost in my hand and it is well made with a interesting clamp setup. I believe the posts should be in stock very shortly, I don't know a price yet but can find out.



These are better but also more expensive. I will eventually have a version of this rear hub but not until at least mid year.



This is not the design that freehub design. I will most likely never make that one. I looked into it and it was to complicated to make unless I wanted to sell $750 rear hubs.

My design uses 4 bearings and only 2 ever spin at any given time. The freehub body is the axle and extends through the hub body. There are 2 large bearings that the hub body itself rolls on when coasting and then 2 bearings on each end of the freehub body/axle that the wheel rides on when pedaling. The engagement system uses a system of ramps and balls to either lockup or freewheel. When freewheeling the balls would act almost like a bearing so that there would be very little drag when coasting.

The Alchemy rear hub uses a 3 pawl system that has the pawl and ramp angles optimized to provide as little drag as possible but still engage fairly quick. The large bearing only turns when coasting other wise you are riding on 3 bearings, 2 in the freehub and one on the non-drive side of the hub.

For all of the wheel builders here is the hub measurements. The center right measurement is the impressive part!

Drive flange = 55.0mm
Nondrive flange = 42.0mm
Center right = 19.6mm
Center left = 37.0mm
