None machined 451 rims?

Do they exist?

I know dahon had them on a few high end models maybe in 406? But can you order them seperately?

Only finding machined ones

Yes with no braking surface on them.

Googling, like a mad hatter, my frame will be here next week.

To clarify - DansComp does have 451 rims. See:

http://www.danscomp.com/products.php...ize=20 x 1-1/8

and

http://www.danscomp.com/products.php...ize=20 x 1-3/8

Velocity makes 406 rims without machined sidewalls, I used the non-MSW Aeroheat rims on my disc brake mini velo build but I had to order them direct from Velocity.

http://store.velocityusa.com/p/aeroh...x_20-406?pp=12

Or they offer the wider cliffhanger rim in non machined sidewall

http://store.velocityusa.com/p/cliff...f-hanger?pp=12

Its funny but the A23 is the only 451 rim they offer now but they don't have that one in non-MSW in any size sadly. I hope this helps

Thanks for that.

I was looking at the cx75 hubs which are 28 hole.

Are all shimano hubs able to take 105 cassettes?

Going for center lock discs, I went for the 6 bolt disc setup because there seemed to be a wider variety of offerings and I got a good deal on my BB7 which came with rotors. I bought Sram X.7 hubs which I have been very happy with.

Any shimano 8,9, and 10 speed cassettes are pretty much universal and should fit any shimano or sram freehub except for some of the newer 11 speed hubs.

Are you looking to go for skinny or fat tires on your build? I assume you are leaning twards skinny given your leaning twards 451s.

Well i found you can get 406 BMX rims from alien nation. No brake rims.

I was thinking of using the cx75 hubs with R517 brakes and they are 28 holes. 10 speed 105 cassette with spacer.

My only problem with BMX rims is the very wide profile of the rim, I went with the aeroheat rims because the rim is only 24mm wide and the 32h drilling works for me.

Not to presume too much but look into the installation and adjustability of those brakes before you buy them.

I would have thought it would be stronger too.

Small diameter is already a strength factor..

so extrusion die making a brake track or not, shape,

is not really a significant factor , but if the theory feels comfortable . go with it..



I got disc brakes and Sun CR18 406 rims, could put disc or rim brakes on them .

they're OK..
