Wilko standard Schwalbe Big Apple RaceGuard. Lidl rechargeable LEDs Something cheap using AAA cells from Planet X Tesco Best. £50 on eBay You don't have to spend big money to have a bicycle. That's why some people associate cycling with people who can't afford a car (or get a driving license) - they don't understand that sometimes bikes are more appropriate or just more fun. Quite likely they never had a half-decent bike or a clue how to ride it as a kid, or friends to go off with on adventures. However I would occasionally bump into some kids who used to be mad keen on bikes of all sorts, and come into the shop often to drool over the latest gizmos - a few years later they were into cars in just the same way, and totally uninterested in bikes. Some of us are fortunate to still enjoy bikes despite having been motorists for decades. :-) |

I have never used slick tyres, which is illogical because tyre tread is used to displace water and prevent aquaplaning. On a bicycle you would have to be travelling about 250mph to aquaplane. |

I guess it gives a thicker layer of rubber without adding weight. (I have never done an assessment of whether there is a difference in tendency to puncture.) Some people have the idea that tread helps with grip and the manufacturers use it as branding. |

The Big Apple isn't a true slick, but it has large smooth areas in between the grooves, and no lumpy bits. My 60mm Big Apples are noticeably inadequate riding up a wet grassy slope, or cornering hard on gravel, but they roll very nicely on a smooth road and laugh at potholes on a less smooth road. I used to ride 19mm slicks on my time trial bike and they also worked well - not as pothole-proof obviously, but they zipped along in a pleasing manner and never had any grip issues. |

Off-road tread most definitely does help with grip, on-road not so much, although with roads being so variable there are some conditions where it will probably help. I wonder if tread doesn't make punctures more likely by giving sharp or pointy things a corner to initially lodge in before they work their way through the tyre. |

(I have never done an assessment of whether there is a difference in tendency to puncture.) Eh? If you put a certain weight of rubber over the tyre, a treadless layer must provide a thinner layer between road and cords than a block tread. Some people have the idea that tread helps with grip and the manufacturers use it as branding. Off-road tread most definitely does help with grip, on-road not so much, although with roads being so variable there are some conditions where it will probably help. It is possible that a significant tread can find tarmac more easily through a thin leaf layer than a smooth tyre. On a stable surface I doubt tread gives any benefit. I wonder if tread doesn't make punctures more likely by giving sharp or pointy things a corner to initially lodge in before they work their way through the tyre. As I suggested above. |
