Even with my recent good fortune regarding the lack of punctures - I know I'm going to regret saying that - there is still an occasional need to remove and replace tyres.

Easing tyres, especially kevlar beaded ones, on and off a rim can be quite frustrating. And how many times do you end up pinching the inner tube between the bead and the rim with inevitable results? Well, I can't praise the Crank Brother's Speed Lever enough.

Reverse is rather more conventional, but the lever is much more helpful at avoiding pinches than conventional levers.
Like I said, reviews of the Speed Lever are either five star or very poor. I can't help thinking the people who don't like it are doing something wrong because it just seems to work so well for me.
