Easily top up tubeless bicycle tires with sealant through the valve using these 3D printed funnels. No more spills or blocked syringes! I provide funnels for both Schrader and Presta valves.
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.
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.
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.
I have had a Spurcycle bell on one of my bikes for almost three years now, and I can’t say enough just how much I like it. It is very loud, built to last forever, and is very compact. I find it that every time I use it I get the attention of the car drivers, even when their car windows are closed. The only negative thing I can say about the Spurcycle bell is that it is very expensive. To the point that I have been planning to get a second one for my other bike, but can’t bring myself to shell out the money. Last week one of my local bike shops was running a sale on Crane bells, and I picked up a Crane E-Ne bell for half the price of a Spurcycle. This post compares the two and includes a video comparison of the two bells ringing side by side.
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.
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.
I took a stab at a tubeless set-up for my Krampus wheels. Here is what I used:
- Surly Rabbit Hole rims
- WTB Ranger 3.0″ tires (fast casing)
- Surly woven nylon rim strip
- Gorilla tape
- Stan’s Schrader valves
- Stan’s Race sealant
- Park Tool VC-1 valve core removal tool
- Sprayer bottle with soapy water
- A 3 gallon air compressor
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.
Last Saturday I was riding in the rain. I had my helmet rain cover on, like I usually do when it’s cold and raining. At some point the rain intensified, and I noted that I was feeling rain drops on my skull. “How funny”, thought I, “I am feeling phantom rain drops on my head even though I’m wearing a helmet cover.”
When I arrived at the destination and took the helmet off…
