There’s no business like snow business

I woke up to fresh snow – not enough to ski, but enough that the door scraped through it upon opening.

This means it’s time to get the winter bike ready. It needed a new rear sprocket. I have written before of the value of a belt drive bike for winter – lower maintenance being #1 on the list. While there is less maintenance to do, when it comes time, the tasks are a bit different than on a chain-drive bike.

The sprocket on top is the old one. Note how the teeth have worn down to sharp edges, unlike the rounded profile of the teeth on the new sprocket below. Changing the sprocket is simple, according to the YouTube tutorial from Gates, maker of the belt drive system. There is an expensive-looking tool – the Gates SureFit Tool – sure enough, I found it on sale for €81.95 or between $133 and $150 US on three sites. It is totally unnecessary. It is for installing the part but not for removing the old one. Installing is the easy part.

While the tool is very impressive-looking, in anodized aluminum with a knurled grip (like the knurled stock on the Official Red Ryder Carbine Action 200 shot Range Model Air Rifle made famous by Ralphie in “A Christmas Story”, or Jean Shepherd in “In God We Trust: All Others Pay Cash” for the literary-minded among you) – it is completely unnecessary and would be a waste of your money. You can watch a second tutorial to see how to do the installation with the tool. (Photo from Rose Bikes)

What the tutorial doesn’t show or tell you is that before you pry loose the “SureFit fingers”, there may be a lock ring to remove. In the second photo, the putty knife is wedged under the lock ring. The “round lobes” on the sprocket and the opening of the lock ring are aligned with the indents on the hub shell referred to in the video. My lock ring pliers would not work on it, but it can be pried off fairly easily with a flathead screwdriver (which is also what you use on the “fingers”). The hub in the photos is the SRAM i-motion 3, which has been discontinued. The sprocket is the same used for Shimano hubs, which is what is shown in the video.

While we’re talking products, I don’t know as I’ve yet sung the praises of the seat pack I bought for the coast-to-coast tour last summer. It was the Evoc 3 liter (the large size) with Boa seatpost attachment as well as Velcro straps to the saddle rails.

The bag can be rolled tightly and fastened with a clip to hold a few essential tools and spares, or unrolled to hold a complete rainsuit as well. It keeps things dry and takes just a minute to expand or contract to hold the load tightly without swaying. It is wedge-shaped – narrow at the front end so as not to rub on your inner thighs when you pedal and wider behind to increase capacity. To carry even more I used Velcro straps to attach other items to the outside of the bag. When open, things may slide out the back, so check the ground before closing up any time you move things in or out of the pack.

When the trip ended I thought I would go back to a smaller bag but, three months later, it’s still back there. I guess I like it.

While the winter bike is ready to ride, the snow tires did not go on today. There are two starts to biking winter here – the day I bring out the belt-drive bike, and the day I switch to studded snow tires. The latter usually comes at the end of December.

Ever wonder what a woolly bear caterpillar becomes? I did. It becomes an Isabella Tiger Moth. Photo from the Farmer’s Almanac.

We are a group of friends who ride bikes. Some of us are fast, some of us are slow, all of us are half-fast. In 2018, one of us rode coast to coast across the US. It was so much fun, he's doing it again in 2022! If we meet Sal Paradise, we'll let you know.
