Dellortoman said:I don't have an answer to how much a spoked wheel will flex. It's dependent on a lot of variables like spoke tension, wheel geometry, etc. but I wouldn't have thought it would be anywhere near 2.5mm. With that kind of deflection the spokes wouldn't last very long before faigue failures start to happen.
The other thing to consider is flex in the caliper mountings or twisting of the forks when the brakes are applied. But again, I reckon 2.5m would be getting into the structural failure range.
So my guess is that 2.5mm is more than enough clearance.
Giving more thought to it (Red wine works wonders):
As callipers are about halfway from the the rim to the hub, the rim would need to move 5mm before the spokes hit.
Given that the spokes on these wheels are 3mm dia, if they hit, I reckon there'd be something seriously wrong! She'll be right.
