Hi All
well, don't know if you know or not, but we have had a bit of a bad winter in the UK
Still, no reason not to cycle my 40 mile round trip ( man or mouse stiff upper lip and all that)
Anyway, the way I go to work is 20 mile one way through remote unsheltered country( no lights, no people, just cow)
there is an 8 mile section that is always the coldest around ....5C lower than anywhere else ( record this year -17C)and the ice pack has been severe this year...still being an "enthusiast" ( translate=man in shed with bike and beer)
i decided to build these home made snow tyres
http://www.youtube.com/watch?v=AlHDMC6rj0Ethey do make a massive difference....if your stupid on them, then you will slide, but for average cycling, 15 mph on packed ice not much problem...
still, wasnt sure if they really made a difference, so during a minor thaw, took them off and replaced with schwalbe marathons ( normal use tyre)
had to walk 1 mile back just to get back to tarmac, as I just couldnt stay on the bike..fall fall fall, dirt. they do seem to make the difference in ice between on the bike and off....simple...
just make sure you do back them off with good tape as in the video, otherwise they will pinch the tube and cause punctures
hope this helps all
regards
