Winter Bike Envy
Someone in our household has a badass winter bike. And it's not me.

Winter's toll. And a winter bike?
Winter is far from over here in Montreal. But because of a snapped gear cable I decided to do a spring tune-up on Wolfgang, my all-purpose, all-year bike. A lot of people have "winter beaters," but to me that never made too much sense: I really like my bike and don't see the point of riding an inferior quality bike at a time that places the highest demands on bike and rider. Especially, I wouldn't want to give up on my hub generator and LED lighting at the darkest time of the year. So far, this has worked well for me and the wear and tear of components didn't seem to be particularly bad. But somehow this winter seems to have been worse than previous, if not in weather but in damage to parts. My rear rim was destroyed a couple of weeks ago, after less than 10 000 km.
And during my tune-up today I discovered a whole bunch of other issues:
It seems tempting to add a dedicated winter bike to the stable, and if I had the resources (and permission from the accomplice) I would probably get a bike with the following features:
 |
| Busted rim |
- my bottom bracket feels noticeably grindy
- the front brakes, Avid Single Digit 7, didn't turn that well around the brake bosses
- the Tiagra front derailleur is sticky and doesn't want to go to the smallest chainring any more
- all the cables and housing are in miserable condition and have to be replaced
- a lot of the bolts, despite being made of stainless steel, show a lot of surface corrosion
- one of the Shimano M424 pedals feels crunchy in the bearings
 |
| This can't be good for your bike, can it? |
- dynohub and lower quality LED lighting (e.g. the B&M Lyt): As stated above, I wouldn't want to give up on my dynohub-powered lighting system. However, for riding in the city I don't need a B&M Cyo or Philips SafeRide light. It's more about being seen than about seeing.
- frame with upright position: A frame that allows me to ride in a more upright position would help in snowy and icy conditions.
- SPD-compatible pedals: I also wouldn't want to give up on SPD pedals and I'm happy with my Lake winter cycling boots.
- plastic saddle: Whereas for long rides a leather saddle is an absolute requirement, for commuting a plastic saddle will do and also take care of the issue of having to cover your saddle---this season I managed to lose 3(!) saddle covers.
- drop bars: A lot of people prefer straight, Albatross, or North road bars for a winter bike; this makes sense from a balance and control perspective; however, my wrists are not built for any kind of non-drop bar, even on reasonably short rides.
- good and wide studded tires: Wheel size is not particularly important for me but good studded tires are a must. And some wideness helps with floating over snow.
- disc brakes (at least in the front): Rim brakes with drop bar levers can be pretty problematic in wet conditions, and most of the time winter means wet roads. Therefore I want disc brakes, probably mechanical ones like the Avid BB7 because of the drop bars. In addition, rim wear is not an issue with disc brakes.
- 2-speed Sturmey Archer Duomatic kickback hub with low gearing: I'm not a single-speed or fixed gear person because my knees don't like me mashing up hills (and hills I like!); at the same time, derailleur systems don't particularly like road salt and constant wetness. A 2-speed Sturmey Archer kickback hub thus would be perfect: no cables, allows to use a 1/8" chain, and has more than one gear. I've never ridden a Duomatic hub so maybe it's not as good as I think.

Review: Innova 700x35C Studded Tires
Back in November, I published a "first look" article on my newly
mounted Innova snow tires. After having ridden them for only a few
kilometer they seemed like reasonably nice tires: cheap, not too heavy,
not too much rolling resistance. Since then I have
ridden the tires for approximately 1500 km and my verdict is very
different now. The Innovas turned out to be a bad investment for me.
The main reason for this are the steel studs. In the initial review I pointed out that steel studs have a reputation for not lasting long, and now I can say for sure: yes, they really don't. I admittedly rode more than usual this winter and a lot of it was not on snow or ice but just bare pavement. But the degree of wear just isn't acceptable. On the pictures you can see that a lot of studs have completely sunken into the tire. In addition, I have lost two studs in the front tire, despite following the manufacturer's advice to break in the tires by careful asphalt riding for the first 50 km1.
The problem is exacerbated by the overall low number of studs. 110 studs make for light weight and low rolling resistance, but on a 622mm tire they limit the performance on ice. I got a taste of that when -- somewhat foolishly -- I endeavored to ride over a bike path covered in snow that had been turned into ice by freezing rain. I quickly realized that this probably was not a very good idea but once you're on the ice there is not much you can do. So I kept going at a very slow pace, but after maybe ten meters it was over. Wham! The front wheel slipped and down I went. I landed on my behind and aside from a painful bruise no physical damage was done. The mental damage, a loss of trust in my tire, however, was quite severe. In my post-accident analysis I've come to the conclusion that 110 studs is not enough for riding on uneven ice on a 622mm tire. A 35-622 tire has a circumference of 2168mm, meaning that the studs are about 40mm apart on each side. On uneven ice that's definitely enough to take you down.
Do I have anything good to say about the tires? Well, they have a nice tread which works well in snow. And as long as the studs were still reasonably new they worked well enough for Montreal conditions. Because of the wear issues I can definitely not recommend this tire; however, if Innova would produce the same tire with carbide studs, like the very similar Suomi Tyres W106, it would make a pretty good commuting tire for urban conditions with infrequent ice. For next season, I will probably switch to something like the Schwalbe Marathon Winter with 294 studs.

First impressions: Innova 700x35C Studded Tires
Update 2012-26-02: I now have posted an extensive review of the tire.
The first snow of this winter has arrived in Montreal, and it was quite a lot. As an avid follower of various kinds of weather forecast (yesyes, I'm soo boring) I was, however, well prepared. The night before I put on my new studded winter tires. I bought them sometime in spring, knowing that in winter it can often be tricky to still find studded tires in stock. The only tires in a suitable size -- my fenders only allow a max of 38 mm wide tires -- that my bike shop had available were Innova Snow Tires in 37-622. The tires have a pretty aggressive tread and a total of 110 steel studs, positioned in two rows near the tire's center.
The Innova website is pretty uninformative, and I also couldn't find much information elsewhere on the interwebs. I'm curious how the steel studs are going to hold up. More expensive snow tires from Schwalbe, Nokian/Suomi, or Continental use carbide studs which are harder than steel and should therefore last longer and will also not rust -- even though that is primarily a matter of aesthetics. In principle, the studs should be replaceable and I'm assuming that I could use carbide replacements if necessary. Measured width was about 33 mm on an Alex DA-16 (internal rim width 19mm).
I paid 40 USD per tire at my LBS, which is a pretty good price for studded tires in North America. Last week I saw them at a bike shop in Montreal for 75 CAD each and on Amazon they sell for 64 USD
(if you can fit 45mm, you can currently get them for 36 USD there). So they're not cheap when compared to normal tires, but in the world of studded tires they're probably the cheapest you can get. And if they prevent only one crash they're probably already worth it.
I took the tires on a first 80 minute test ride on the night before the snow actually arrived. It is advisable to break in studded tires, i.e. riding them without hard cornering or braking, for a couple of kilometers in order to allow the studs to set themselves in the tire and avoid losing them prematurely. So I rode along the Lachine Canal bike path, which was mostly dry with some icy puddles. On dry pavement, you can clearly feel the increased rolling resistance of the tires. Up to now I have been on Vittoria Randonneur Pros in 35-622, which roll very nicely, and thus the difference was very noticeable. The best way to describe the feeling of the tires is "riding into a slight headwind." What is even more noticeable than the rolling resistance is the noise of the tires: people often joke that you can take off your bell when you're riding studded tires, and I have to agree: the sound is very similar to riding on fine gravel, even though I think the tires have gotten a bit quieter on the third day. There were some frozen puddles on the Lachine Canal path, and I somewhat cautiously tested riding over them. All went well and so I got a bit bolder: Braking on the ice also worked pretty well.
The next morning I rode into work once the snowfall had mostly stopped. I tried going my usual route on the Lachine Canal, but they don't clear the snow there at all and riding through deep snow wasn't too awesome, even with the new tires. At the next intersection I therefore turned onto the streets which were more or less snow-free. On the more snowy parts, the tires performed reasonably well -- I would say better than the Ritchey Cross-Pros I had been riding during the past winter, but it's hard to tell. On the way back, the roads were mostly snow free, but I did go across an icy pedestrian bridge near Atwater Market. Here the studded tires were great, and I think not having to worry about icy patches that can often be hard to spot is the main advantage of studded tires.
Since then it had gotten warm again and I have taken the tires off. The next snow and ice will come soon, though, and I will probably post an update at some point.
