Sapim Laser on disc wheels, carbon rims
Moderator: robbosmans
Hi all!
I'm planning a wheel build soon for my cyclocross bike, it'll go:
Hubs: Hope Pro2 Evo 28h
Rims: Light Bicycle U-shape, 35mm, 28h
Spokes: Sapim Laser
Nipples: ?? whatever goes
I've seen that sapim recommend that you don't use the Lasers on disc wheel, I guess that's for stiffness reasons. I do however have a set of XC wheels with laser spokes, aluminum rim which works just fine for me. DT Revo's are the same dimensions apparently, so what problems would a wheel builder face when trying to lace these up? Would tension be the issue? wind-up? or would it be just fine to build up the wheels with them? (I'm 60kg if that makes a difference)
Open to any experience you guys have, I'm very much a noob at this, cheers!

With a stiff rim like that, 28 spokes, and only 60 kg, imo lasers will be fine. You'll have to take care to avoid windup but it is manageable. In fact, since you're ordering from Light Bicycle, you can order some Pillar 1420 spokes for like $1.60 each. They are the same weight as lasers but bladed so it's easy to grab them during the build.
At 69kg, my cx wheelset for the last two years has been xr200 rims in 20/24 laced to lasers. It is rim brake. I haven't had any problems related to the spokes.

Use laser in all my own personal disc brake wheels and they are fine. I am heavier as well. I even have a 24 spoke wheelset with cx rays which are the same as a laser in terms of stiffness.
Good to hear! I was thinking about using pillar spokes but was wondering how I'd get my hands on them in Australia. If that's the case i might use the 1420's, I guess it'd help with wind up. How do I go about choosing spoke lengths? Is the DT calculator trusty enough to use?
