Thanks. Yes they are Ritchey Speedmax. They have been swapped around from bike to bike and in steady use for about 2 years. Most of that time on a rigid C'dale that a friend uses to commute to work, short road rides and mild offroad trails. They need replacing now, but I think they lasted as long as you could hope for. Good combination of on and off road capability. I'm planning to get another pair for a similar bike I'll be building soon.
