Schwabe vs Conti

My usual steed is a Stromer ST-1, and during the winter it's equipped with Schwabe marathon tires. It's been very good. Today I had dinner plans where my folding bike would have been ideal. But it was foggy and a bit icy when I started, so I grabbed my old Gary Fisher which has some Conti studded tires.

The weather was worse than I expected, light snow, but things were icing up fast. So I was fighting losing traction all the time (indeed, there was one spot where I needed to walk up a very steep hill to cross a trail ... and fell ... I'd expected the studs to grip better).

Others have similar experience? Changing bikes as well as tires makes the comparison a bit sketchy in my book....

If I understand correctly, the base was icy but there was a light layer of snow on top? If so, it is not too surprising that you lost grip. Bike studs are typically only 1mm in height and even if the light snow was compressed by the tires to a much thinner thickness under the weight of your body and bike, they might not have protruded enough to get a really good bite into the ice. Furthermore, the rest of the tire would have tried to get traction on the thin coating of snow which would have had no traction on the icy surface below it.

I encountered a bit of that this morning and my rear tire slid out a bit, not enough to fall, but enough to lose traction. And, going up a slope, you need more traction and it appears that your studs couldn't reach through the snow to get enough of a bite into the harder icy surface below.

I read once that using studded tires is akin to summer (smooth or at least smoother) bike tires on sandy grit over pavement. 45Nrth does make some concave studs where the tip protrudes 2mm from the base and some screw-in studs protrude 2mm as well but typically, bike studs are 1mm.

My point/query is that the Schwabes work better ... the studs aren't visibly longer (indeed, due to the extra several thousand miles on 'em, most certainly shorter now ;>) ... is my experience with the conti's vs. schwabes match other people's or not?

The irony of only falling while walking isn't lost on me (indeed, I ought to have found my yaktrax ... but they've been in hiding so I was relying on the bike more than my shoes ;>).
