Strengths: weight,size,power,run time,clean and uncluttered design.
Weaknesses: needs q/r. early days yet,interesting to see how they hold up over the next year,and where the design goes from here. too early to answer the reliability question
Overall: brilliant,if your sick of strapping stuff to your bike but still want the power to go off road night riding then these are highly recommended.weight is so little i`m going to leave them on my bike all year! power is ample for off road and with a spare battery i get 5 hors of riding.superb! too early to answer the reliability question yet.
Weaknesses: a tad heavy but worth the sacrifice for reliability.lever reach should be adjustable.
Overall: These brakes are awesome.after many sad endings with hope/formula/magura brakes,i was after something i could use that did`nt let me down or overheat every 5 mins.weight is an issue but these brakes make up for it in solid build,performance.power is amazing with no overheating on long alpine decents.thoroughly recommended from hard xc to dh.finish could be a little nicer(like hopes)but it`s not at all bad and well worth the money.
