Of course, I should have mentioned ...
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.
I have been using a device which people either seem to love - ***** - or think is totally useless - *.
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.
To get a tyre off, just extend the lever - it's like a telescope - hook the lever under the bead and clip the other end onto the axle, push the lever around the rim, like a second hand on a clock, and the tyre just pops off the rim.
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.
