Strengths: I've ridden them on wet and damp roots, logs, mud, dry trails and gravel roads and they grip superbly. They are a bit sketchy on very greasy mud but then, I guess, most tyres are.
These tyres seem to be a genuine 1.95" unlike some Specialized Roll-X 2.0" I bought recently which were more like 2.3's and wouldn't clear my chain stays! If you want a set of un-used folding Roll-X 2.0's (harder compound) mail me at guyrwood@hotmail.com.
Weaknesses: None really, they're grippy, hard wearing and very light (~500g). Very expensive at £27 a throw!
Strengths: Compared to a Cateye set I tried a while back, this light is neat when it's installed - no great fat coiled wires and switches everywhere. Neat, straight, short cable and the on/off is on the light itself.
Not bright enough for full speed single track but ideal for trail cruising at night. Got plenty of quizical looks cycling back through my village in the dark!
Weaknesses: None really, it would come with a smart charger in an ideal world.
