Strengths: Great power at your fingertips, easy to use and good sealing from the elements. can also be over volted
Weaknesses: cheap, flimsy mounting bracket broke after 1 year but i suppose it served me well during that time.... :-) battery is heavy for all u weight freaks and um short battery life on full power although, that is to be expected
Overall: great value for money, but durability is a factor to consider. if u dont mind replacing them every year or so then they are great. they are powerful and bright, ideal for light offroad or onroad commuting
'unreliable and a serious saftey risk, save up and get a hope'
Strengths: well, it performed well when on the road in dry conditions
Weaknesses: i had one fitted as standard on my new raleigh fidhbed. it failed twice by leaking from the caliper without any explanation and three times from the lever mastercylinder. the whole system was replaced and it still leaked and this was from mostly roadriding. it didnt suffer any harsh treatment also, when mine got wet, the mastercylinder piston refused to return so the front wheel couldnt be moved. this happened on both the old and new system. also (yawn) the cheap plastic levers always felt spongey resulting in a cheap feel and loss in performance due to flex in the lever
Overall: although magura uk were very helpful, i would not trust magura disks again, the hs11 on the bask performs flawlessly but the julie on the front is more hassle than its worth. my advice is to do what i did and save up to get a hope 02. it feels great and performs excellentley.
Strengths: once bedded in, amazingly strong, compared to the magura julie that i had before, its also durable and looks the part. the open system works a treat when it comes to dealing with heat dissapation and very hastle free-fit and forget
Weaknesses: um, takes a few days too bed in but when u compare the weeknesses to the strengths, its hardly worth worrying about!!!!, its a perfect brake
Overall: its a great, worth while upgrade that will give u ure moneys worth. performs well and reliably in all conditions, flawlessly, buy one and put it on the front and you cant go wrong!!!!
