I've seen online a lot where someone says that they have a bike with 30mm tires and ask if they can put ~45's or whatever on it... -and everyone else says "yea sure, if the tires will fit in the frame/fenders". And it's true that it works, but it works lousy. I'm usually the only one pointing out that you don't get the full benefit of fatter tires unless you move to wider rims as well. It goes something like this: 1. The only reason to run fatter tires is to run them at lower pressures, to absorb road bumps better. 2. But if you get wide tires and mount them on narrow rims, then you have to keep them inflated to fairly-high pressures to keep them from squirming and folding over in turns. 3. So if you mount a fat tire on a skinny rim, all you end up with is a much heavier, hard-riding tire. The fatter tire's greater cushioning ability is lost with the raised inflation pressure that becomes necessary. I totally agree. A wider tire on the same rim inflated to same pressure (that is what most people do) results in a much harsher ride. I see no point in getting wider than 25 mm tires on rims normally used for road bikes. As for Mr Heine: I consider him to still be green, as he hasn't graduated to recumbents yet. Who is this Mr Heine? Lou https://janheine.wordpress.com/ He's a guy developing a market niche. He sells Compass products and is now making Rene Herse products under a some sort of agreement with the Herse estate. https://janheine.wordpress.com/2017/...y-of-function/ https://en.wikipedia.org/wiki/Ren%C3%A9_Herse Probably made in the same Chinese factories as Velo Orange: https://www.compasscycle.com/product...ry/rene-herse/ WTF? $550 for a triple crank? Yikes. I remember back in the mid to late '70s going to the Wheelsmith shop in Palo Alto. It was hardly more than a shed, but it had all these old bikes out front -- including a few Rene Herses with odd-ball derailleur systems and old rusted parts. It was the one and only time a bike seemed creepy to me. https://tinyurl.com/yblk6cqy A few hundred yards away was Palo Alto Bikes with Tom Richey building modern frames. I liked fast-back stays, although some of his weren't all that well executed, IMO. At the time, my index frame for awesome was the California Masi. https://belle-macchine.com/2014/03/1...gc-california/ Then I ran into a Bruce Gordon http://www.classicrendezvous.com/USA...lman-Jones.htm That renewed my interest in fast-back stays. Caylor's fast-back stays were nice, too. Back then, nobody was impressed that you wore wool or rode a steel frame. Maybe you could be more cool than the next guy by drilling a few more holes in your crank. -- Jay Beattie. I bought a drillium chainring back in the 80's (can't remember the brand). I don't think I could have gotten any more **** from the peloton if I had been wearing a tutu |

I like to see ones that look as if they've been really used, and have actually been somewhere. Somewhere far. -- - Frank Krygowski |

BTW, another reason I like a helmet is because the mirror on it lets me ride with or without sunglasses and I have the mirror with me no which of my bicycles I ride. Ditto for external battery light versus dynamo lights. What works for one may NOT meet the needs/wants of others. I use eyeglass mirrors that fit on my normal glasses. My glasses darken in sunlight, so I don't bother with sunglasses. I've made my own mirrors since the 1970s, each one from a few inches of wire plus about two square cm of plastic mirror material. They weigh about 2 grams, according to the electronic scale I was recently given. I keep one in each handlebar bag. Doesn't the change in focus from looking down the road to looking at a mirror close to your eye bother you? I made one of those wire and mirror devices and the change in focus from watching the road to looking in the mirror about drove me crazy so I went back to looking over my shoulder. Cheers, John B. |

They look much like a hard tail MTB but with much wider forks. Fatbikes have been out for a while now. The only thing that irritates me about them is that they bitch about 'skinny' MTBs riding on "their" trails and leaving ruts - ignoring the fact that the trails they ride are usually multi-use, and get beat to **** by walkers, snowshoes, xc skis, and horses. I call them "fatbike fashionistas". As I don't ride "in the bush" I only see the so called "fat bikes" on the road, but they certainly look cumbersome. Cheers, John B. |

I have no problem at all using the helmet mirror or the eyeglass mirror. I prefer the helmet mirror because my eyeglasses do NOT darken as Frank's do. If I put an eyeglass mirror on my sunglasses over my regular eyeglasses then I have problems seeing into the mirror. I prefer the helmet mirror because of that. Cheers |

Skinny frame, our bikes were much stronger with a double top tube, and skinny tires that the guy was inflating with a long hand pump - we inflated our tires at the local gas station air hose. But the rider ( a Dartmouth Collage student) had ridden all the way from the collage, a seven mile trip, so we were suitably impressed. In fact the idea that one could actually go somewhere on a bicycle influenced us to do the same and we actually made a 15 mile out and back ride a number of times. Then, of course, I turned sixteen and started driving a car :-) Cheers, John B. |

I shall have to try the helmet/eyeglass mirror again. I don't find that looking back over my shoulder is difficult but the "looking glass" might be easier... if I can focus on it. As I had cataracts removed from both eyes, my eyes are now pretty much fixed focus - one close, one long. Cheers, John B. |

I made one of those wire and mirror devices and the change in focus from watching the road to looking in the mirror about drove me crazy so I went back to looking over my shoulder. Assuming a flat mirror (which is what I use), looking in the mirror doesn't require a change in focus, in the sense of adjusting the focal length of a lens system. Objects in the mirror are at the same distance they would be if you turned around. What's required is aiming your eye at the object in the mirror, and more crucially, getting your brain to pay attention to just that eye. I think the latter is the bigger problem for most people in the U.S., where the mirror goes on the left, but most people are right-eye dominant. I had to learn to temporarily ignore my right eye's image back when I first used an eyeglass mirror, and IIRC it took a few days to be comfortable. It wasn't until years later that I realized I had a habit of blinking as I shifted my gaze to the mirror. Perhaps that gives my brain a needed disconnect, allowing the left eye to gain temporary dominance. -- - Frank Krygowski |

Cheers I tried a couple of helmet mirrors and while they work for seeing behind I found that they presented a blind spot when coming to intersections. Now I use a bar end mirror on my drop bars that seems to work well enough. Useful especially when commuting in traffic. -- duane |
