General Etiquette: Please only edit values if: a) you know what you're doing, and b) can post a photo with vernier caliper showing the measurement in the RM thread

Other stuff: Keep main table for factory / retail brakes, for frankenbrake calculations scroll down this page and use sandbox. See extra sheets "Fluids" and "Weights" (tabs at bottom left) for other info.

Comparison / ModificationPercent
Description of results
Additional Side Effects
62
M785 to M820 gain6.2%
The M820 brake generates 06.2% greater braking force than M785 (lever differences not checked)
Longer throw, greater pad area
63
Stock RO-R to Custom RO-R / Prime gain
-24.3%
The RO-Racing lever on Hayes Prime caliper gives ??% greater braking force
Longer throw
64
Stock RO-R to Custom RO-R / V4 gain
The RO-Racing lever on Hope V4 caliper gives 6.27% less braking force
Shorter throw, greater pad area
65
225mm vs 203mm rotor9.8%
The 225mm rotor gives a 9.78% increase in braking force over 203mm
66
26" to 27.5" wheel-4.0%
The 27.5" wheel results in a 4% drop in net braking force at contact patch (approx)
Further effects exist due to increased moment of inertia
67
27.5" to 29" wheel-6.0%
The 29" wheel results in a further 6% drop in net braking force at contact patch (approx)
Further effects due to increased moment of inertia
68
Hope E4 to V4 gain11.7%
The Hope V4 brake generates 11.72% greater braking force than the Hope E4
Longer throw, greater pad area
