I was going to boldly say "no-one has made a rear hub dynamo" but then I did a google search and I'm glad I didn't say that, because I would have been wrong. Shimano make the FH-C810 which despite the FH suggesting "front hub" is actually short for "freehub". In full it's the "Shimano Nexave Di2 FH-C810" (page via searching their site for the short code). ...

Real track bikes don't have brakes. You need brakes for commuting, especially in a city, and at least 2 independent braking systems. Not all frames and forks have brake mounts. You also won't have fender or rack mounts which are nice in wet weather. Ergonomics and geometry can be an issue, given that track bikes tend to be a bit twitchy and aggressively ...

Using the scraping tool or sandpaper to abrade the patch area may also leave the tube thinner. When inflated the thinner area stretches and may allow air to leak. You might have to stick the (temporarily) inflated tube under water to find these tiny leaks. Scrape sparingly, and the tube may still have plenty of life left. I am still riding a tube with six ...

As well as checking for debris in the tyres, applying the patch properly etc., you need to be careful not to give yourself a "pinch flat" when you put the tyre back on the rim. This is caused when you trap the tube between the tyre and the rim, putting a fresh hole in your recently repaired tube.

In short: Patching a tyre is only temporary and should only be used to get back home after which it should be replaced. Long Version: There are many reasons why patch may fail. Some of which may include the adhesive and rubber patch quality as these may be very cheap patches. I generally never use any of the cheap patches that you can get out of the dollar/...

Option 1 - Nothing Many fixed gear riders are short distance, and tend to be close to home. The creed is to remove superfluous things from the bike making it lighter and simpler. Why carry tools at all? All you need is a cellphone, or some way to pay for taxi. Some tyres have a phenomenal puncture resistance, so this makes punctures less likely, at the ...
