The Magic Mary is designed for xc and dh type mountain biking in wet conditions and generally used on the front only as its has good grip and has fairly high rolling resistance.
Not at all suitable for road riding.
Typically a faster rolling tyre is put on the back , unless the conditions are very extreme or you are racing in bad conditions you would put them front and back.
I use them for my mtb.on the front and really inspire confidence.
I would recommend Schwalbe Marathon Extreme Evo tyres , I use them on my 700cc Touring bike for mixed road and forest tracks and mud.
i.e gravel riding in Scottish Borders.
Roll pretty well on road, grippier than they look off road and long lasting tread.
Be a bit careful in mud but they do grip well, the 700c version would be narrower then the 26 version so this may help in soft conditions, but very pleased with them, all tyres are a compromise, hard to get a good all rounder, but do like these.
Plus pretty puncture proof, never had a puncture inspite of the lots of abuse.
Only 1 puncture was a pinch flat , desecending a fast fire road with not enough air pressure in tube, so it hit rim.
SJS sell them.
