Before the week is out I'm going to hit 1600km/1000 miles on these spikes I mounted last week of 2020. Apart from a couple of weeks where cycling was too treacherous even with spikes, I've managed to commute right through most of the winter where regular tyres would have probably let me down or at very least taken the fun out the rides.
In Berlin, we tend to be 2 to 3 weeks behind on spring weather and have had frost most mornings including today. We even had a light snow covering on Friday last. Looking at the longer range forecast, I will probably want to keep the spikes on for at least the next 14 days to avoid slipping on icy patches on my morning commute. But I am also really looking forward to returning to my regular Marathon Plus and the reduced rolling resistance and noise over the spikes.
My rolling summary report on these Schwalbe Winter tyres (the cheapest spike option I found) is this:
1) If you plan to ride through the winter in FROSTY or ICY conditions, spikes are a great recommendation. There is a limit to their effectiveness in snow- but a noticeable safety benefit for those who want to ride rather than leave bike in the shed during the winter and not to feel caught out if the weather changes unexpectedly
2) I've manage to maintain/increase fitness levels on my daily commute as I've pulled my average speed up to almost what it was prior to fitting spikes- despite the increased drag and road noise. With regular tyres I would not have been able to ride safely much of the last 3 months and would not have got the exercise otherwise.
3) I can recommend anyone buying spiked tyres to purchase some spare studs and fitting tool (cost approx EUR 9 /GBP 7.50 for Schwalbe tool and 50 tungsten replacements). I've lost 3 studs in the last 3 months, and refitting any lost studs is a 2 minute job- where the first minute involves unlocking the shed to get the tool out and less than 60 seconds needed to refit
4) You get used to the noise of spikes. The fizzing/fat frying audible accompaniment generated when riding on spikes was disturbing at first. But now I hardly notice it. It is comparable to the difference in noise for those who have ridden MTB tyres and switch to e.g. Big Apples. You'll be so used to the noise that you only notice how quiet everything is when you are NOT riding on the former and notice how the latter are 'silent' in comparison. In fact, when I ride together side by side with my son, his MTB tyre droning drowns out my spike noise.
5) Although my experience has been positive- I really am looking forward to the lower resistance of my regular tyres I hope to refit in the coming 2 or 3 weeks once conditions look stable enough. But I will definitely store these winter tyres safely so I can remount and ride safely in future winters.
6) Do your homework if you plan to buy such tyres. I had a puncture just short time after fitting the brand new tyres. The puncture guard level can be different even on otherwise similar looking tyres. Schwalbe Winter and Schwalbe Marathon Winter look almost identical except for number of spikes- but the puncture protection in the latter is way better than the former- as I learnt the hard way.
I also considered fitting one of my 2 spare bikes with winter tyres instead of the Rohloff. However, an IGH has an advantage over derailleur in snow and ice which can clog and jump in snow/ice/mud. A Rohloff powered steed with its lower general maintenance levels and high reliability is perhaps a better winter bike than using one of my spare bikes for the winter conditions. I am glad I rode my best bike through the winter knowing those 14 gears would not let me down whatever the weather.
Now bring on the sunshine
