I'm back on my daily commute since last week- shod with the Schwalbe Winter tyres previously mentioned. These are the 120 stud tyres and not the 240 stud version.
Tyres are already over 200km used, so I passed the 'wearing in' phase- and all studs are still in place.
The weather in the last days would have likely put me off riding after my broken rib experience 15 months ago, but I have to say that these winter tyres do seem to be pretty effective for the conditions I have experienced so far.
My 16km commute involves a number of different surfaces/conditions and prior to winter tyres I had an approx 10% longer winter commuting route to avoid some of the more challenging conditions. But I've managed to keep to my preferred regular route made possible by these tyres. A win of around 10 minutes each way back to my life
My route involves around 3km on smooth tarmac bike paths (can prove slipperiest conditions on my route) and 3km bike paths with paving slabs and occasional cobble stones. About 6km is on the road with the regular traffic- with 4km on tarmac and 2km on concrete surfaces. 4km is a shortcut through the woods on compacted permeable surface with lose gravel on top for the most part. In the winter or on wetter days this can get muddy and slippery in places enough to make it unrideable on my 42-622 regular Schwalbe Marathons road tyres forcing a 10 minute detour on some busier roads to stay upright.
Since mounting the Schwalbe Winter tyres I have ridden in freezing, icy, frosty, snowy and wet conditions (all in the last 7 days!) on my shorter forest commute route.
The tarmac bike paths still prove the slipperiest. The tyres hold well, but where I have had to stop for traffic lights I need to be careful not to slip when I put my feet on the ground!
The tarmac and concrete road surfaces tend to be less slippery as they are treated by local council, and these are mostly perfectly rideable. Where ice has formed on puddles, these have been approached with caution, but the spike have proven their worth in not slipping even then. The cobble stones (often on crossing with major roads in Berlin) are more of a challenge. The winter tyres/spikes do provide better road holding, but I am still cautious as there still seems to be less grip than on the other surfaces.
As for the forest. This was my no-go when wet or in snow on old tyres. But on icy mornings where the ground has been hard, this part of route was not just rideable, but even fun! On a clearing where 4 paths meet, it was often too slippery to ride, but the spikes kept me up when I saw an MTB with offroad tyres struggling last week. And for the homebound commute, where surfaces were muddy and previously unrideable for my 28" road tyres, I could navigate that stretch without having to slow too much or get off and walk. A huge win for me, especially when I overtook some younger adults pushing their MTBs on same stretch
Worth it? For me, yes. I haven't had deep snow (1cm max which melted same day) but the 120 spike tyres have given me the confidence to keep riding through the winter. If you live in an area with more snow, then knobbly MTB style with more spikes might be more appropriate, but for city/town slickers who are mostly on road, these 120 spike Marathon Winter get a big thumbs up from me. My commute is slightly more sluggish due to tyres, but only a couple of minutes longer on 16km vs same route on Marathon Plus. But still quicker than my bad weather route!
I have no experience of other brands of spikes. But German bike magazines rated the Nokian and Continental spikes slightly better. However the price point of the Schwalbe (approx GBP 20 a tyre) effectively gave me 3rd best performer at half the price of the competition. And they are really pretty good for my needs!
Although I haven't lost any spike yet, I combined my tyre order with a bag of spare spikes and the tool needed to fit them for approx a fiver more. If I had to order those separately at a later date, the postage would have cost about the same as the extra spikes! I ordered from bike24.com who deliver to most countries if you cannot find locally.
Stay safe (and upright) in 2021
