Repair Sidewall of a Tubeless Tire
I have a pair of Snoqualmie Pass tires on my road bike, set up tubeless. I absolutely love them, but I got a small cut on the sidewall of the rear tire. The tires still have a lot of life in them, and, considering that they are not so cheap to replace, I decided to try repairing the cut.
[Update 4 months down the road – May 2021] The repair is holding just like the day I made it.
Schwalbe studded Winter Marathon tires set up tubeless
Last winter I switched to using studded Schwalbe Marathon (HS 396) tires for winter commuting, and I have been wondering whether I can set them up tubeless. My reasoning is that I really don’t want to deal with a puncture in the winter. For one, road side repair is pretty much out of the question because my fingers would freeze off and the patch would probably not adhere in sub-freezing temperature. Considering that I usually dress fairly lightly when I cycle in the winter, the prospect of pushing my bike home is not very appealing.
Alex Rims SX-44 wheel review
I urgently needed a new rear wheel for my winter bike, and ended up buying an Alex Rims SX-44, the 29″ variant. This is clearly a budget disc brake wheel priced fairly low, but from the description it seemed like a no-nonsense wheel with decent components. My goal was to set this wheel up tubeless with Schwalbe Marathon studded winter tire (HS 396). Below are some facts and thoughts about this wheel.
Shimano SLX (M7000) and XT (M8000) single cranks are exactly the same as double
I got an M7000 SLX single crankset for my Krampus, and was surprised to see that it has a second set of chainring mounting holes. Did they sell me a double crank instead of the single? I was perplexed and unsure whether I should return the crankset, so I set out to find out the truth.
A case against spoke protectors
There is a lot of dislike among cyclists for spoke protectors. They (the protectors) look ugly and many think that they are only necessary if you don’t know how to adjust your rear derailer properly. I know how to adjust the rear derailer, but on one of my bikes, for whatever reason, the chain jumped off the big sprocket and into the spokes. After replacing 6 spokes because of that incident, I have been firmly in the minority that favours spoke protectors. However, today I observed something that made me want to remove spoke protectors from all my bikes. Strangely, I have not encountered this argument against spoke protectors before, so I decided to type this up.
An improvement on Sheldon’s fixed cup removal tool
I had a really hard time trying to remove the bottom bracket fixed cup from my friend’s Elvish French bike. I replicated Sheldon Brown’s fixed cup removal tool, although my local hardware store did not carry any 5/8″ bolts, so I had to resort to a 1/2″ threaded bolt. I believe that I have made two improvements to the tool, which I’ll detail below.
