Building some new road disc wheels up. I'm assuming 2 cross is the standard for both front and rear 28holes? 3 cross is impossible?
Why would 3 cross be impossible?
I'm a newbie to building wheels but my (fallible) memory is telling me that my great uncle made some.
Why would 3 cross be impossible?
As you reduce the spoke count the angle required to get three crosses get's more and more extreme. At 18h 2x the spokes would be at a more extreme angle than 32h 3x. Conversely 48h 3x looks practically radial.
I've no idea if 3x is necessary, I'd have thought it possible though.
I'd be inclined to try it because the number of crosses adds nothing to the wheels strength, they only resist torque, and MTB's have always used 3x for disk braked wheels.
My 28h Bonty wheel is laced 3x. Must be possible.
3x is definitely possible with 28H, but it does give a quite sharp angle as the spoke leaves the hub flange. You can't build 3x with 24h though.
I've messed about with 2x 28 h builds but the extra spoke strain does make a real difference at 28 spokes. I've broken quite a few. Despite the cleaner exit from flange I'm still going 3x on 28h builds until I prove to myself that spoke breaking on 2x is just bad luck. I'm not holding my breath.

wrong, 3 cross is standard down to 28 hole
"spoke strain"?
"spoke strain"?
File under 'sex face'
I've remembered some wheels my great uncle made were 3 cross 28 spoke road tubular wheels.
Sight thread drift are there any wider 28h rims (that aren't carbon or silly money)
DT swiss make good 28 hole rims. XM481 30mm internal. I bought 401's and wish I'd have gone with 481's.
