Weaknesses: everything else just the biggest mistake ever produced buy mbr.
Overall: I could do a better mag sat on the toilet what a waste of time and how much stuff do they get. "oh look at me i'm a goth wow lets thke the rip out of xc'ers coz I think it is not cool" go home we don't like it!
Weaknesses: can seal up when pumping up (dose that sound strange) heavy and an inner tube should be as light as possible (reduce rotatinoal mass) but if you are a prone then this is a good advantage! exspensive for inners
Overall: they are good i took a set yha'ing and got home took my old worn must bin tires on and i had: 4 thorns 2 bits of glass in my tubes without noticeing!
'thought they would be crap better that some £30 though'
Strengths: fast rolling light will not let you stack on wet tarmac. hard wearing
Weaknesses: nothing
Overall: ive been using these since bike 2000 i got them for £10 at the leisure lakes stall i was using some velicoraptors and they were as bald as pantani! so used this and they still has there fury bits!
