"What ABS is brilliant for isn't maximum braking force, it's much more about maintaining control when a sudden panic brake is required. I'm quite happy to do without ABS in my three wheeler but am delighted to have it in pretty much everything else."
Exactly... that's what I said I think. Actually it depends on the road surface. Gravel builds up in front of a locked tyre and helps braking considerably, as does snow. Braking hard to just before abs kicks in is the same efficiency as braking in a car without abs, one is braking to just before lockup. In other words, there is no way of stopping more quickly than properly applied brakes. Abs and cadence braking allow you to add steering that's all....I say, that's all, it's a pretty big advantage to be able to steer round the obstruction if there's room. But abs won't stop you quicker if there's nowhere to steer to. If you think it will, you need to get out and try it!
