It's the way of the world now, when a 22 year old with a CadCam software can displace an experienced engineer. Hell, we just changed a worn 53t 2009 Campagnolo chainring on a Record carbon crank which entailed _both_ chainrings _and_ the bolt set for the 2011 style which are available, the 2009 being incompatible and unavailable.. And Campagnolo is not the worst of it. Thank goodness I have four sets of TA cranks and over a dozen unused chain rings. Those should see me out. I'm still using my Ritchey Logic 110 mm cranks on almost all my bikes. Ought to be rings available for those for a long time. And, LOL, 8sp Shimano cassettes. Seems like the dark ages now, what with 11sp being de rigeur, except for one bike with a 7sp freewheel which I guess is the darker ages. But it's a 135 mm OLN and thus has almost zero dish- same spokes since 1996 with no breakages so far. Sooner or later... Not a "disc" brake in sight in my house (except that rim brakes are disc brakes). One bike with brifters. No CFRP, no AL or Ti frames. All Brooks saddles of one sort or another. Tan wall tires, polished rims. I'm not keeping up with the times, I guess. What a Luddite! But hey, I do have one of those fancy newfangled ISIS BBs on one of my bikes. Wait, those are 15-20 years old too... ISIS sucks. I went through ISIS BBs like Kleenex. I was happy when the crank broke, and I was rid of it. My only old bike is '69 Raleigh Pro track bike -- all NR components with wheels I built back in the '70s. Its now my roller bike. My fleet of four road/gravel bikes is relatively new because of breakage or theft. All discs except one. Three STI, one Di2. No leather saddles, which I never liked. One aluminum and three CF frames. Each one loved and cherished. I do regret upgrading my commuter, but I sort of had no choice. It's a warranty replacement frame (CAADX) designed for hydraulics, and the cable brakes didn't work well because of cable routing and housing friction. Upgrading to hydraulics meant going with 11sp. 11sp chains and cassettes wear too quickly. It's nice having all the gears, though -- but certainly not necessary. I also miss not having a through-hole in the crown of my commuter, and I miss the threaded BB. The CAADX frame came with BB30 and a CF disc fork with no through hole or front threaded boss for my dyno light -- just a threaded boss in the back. I might drill one -- its an aluminum steerer, so I know there is metal in there somewhere! One good thing about discs (besides stopping well) is that I can use giant tires -- like 35mm studs on my commuter with fenders, assuming it snows. Discs are a plus for me. -- Jay Beattie. And then there's pilot meatware, an essential component of bike control. This came to me today from Evanston IL as part of a longer email. His Eastman is a Raleigh Dl-1 Roadster clone modified with cantilevers and 700-40 Michelins on aluminum rims: " Interesting mechanical story for you. Was out riding the Eastman with a friend. He was on his 15 pound BMC with Dura Ace hydro discs. It was wet, puddles, rain had stopped but misty. Rims completely wet. We're chatting away and were inattentive. Coming up to a T-intersection and planning on a left. Visibility to the right is badly obstructed. It's a 20mph speed zone but with school, park, train station, old folks home, shopping, traffic is normally quite slow. Except when someone is coming through at 40mph. So full panic braking. Which I had not done on the Eastman in all the 15 years I've had it. Brakes grabbed immediately in the wet. No excitement at all. " My friend had a harder time. His back tire slipped and came around. Car was gone by time he was stable. Way too close. He was doing a lot of things right. 28mm GP5000 at 70psi. Not sitting as low as I would prefer but lower than the guys he rides with. Jerry is late 50s and is still in the 40mph sprint group every Sunday. Ten years ago he was driving the train, now he's wheelsucking, but he does it. One thing surprised me. He did not slide off saddle to rear, did not weight back wheel. Had never even heard of that. He's a flatlander like me but has probably visited the mountains more than I have. He just never learned to do that. Even with 66 degree seat angle I was off the saddle and back. " Moving weight back is not magic or special knowledge for an experienced cyclists. I'm suspicious of the stories about the guy who is the Cat 2 quality rider who doesn't know about getting his or her weight back to panic stop. It's always some story of a guy on 40mm tires schooling the guy on the 15lb bike. One part of the story that does resonate is skidding the rear wheel. A rear hydro-disc has far more rear braking power than calipers or cable discs. It takes a few rides before you learn not to be ham-handed. I fish-tailed a few times when I was getting the hang of it. Rear brakes tend to be squishy, and you don't get that with hydro discs. I don't doubt that you get the hang of it in a few rides; but I'd worry about when it comes up in a panic situation. Will you still have the hang of it when it's just the lizard part of your brain operating your muscle memory? - Frank Krygowski You get much better feedback with most disk brakes than you get with for instance old V brakes. As you mentioned more than once her you don't come in panic situations so you don't have to worry. Lou |

The brake pedal required almost no foot pressure for a normal stop. I'm sure that if a really fast stop had been required within the first few weeks of ownership, all four wheels would have locked up. I'm also sure that most modern drivers, if given a chance to drive that (now) antique, would lock up the brakes. The second example: I've always owned cars with manual transmissions, although I've driven automatics plenty of times. But I recall an incident when I drove an automatic and decided to use two feet for two pedals - that is, I used my left "clutch" foot for the brake. On that drive, I slowed for a traffic light, and just before I got to the light, my left foot twitched habitually, since it was used to pushing in the clutch at that moment. No harm was done, it merely caused the car to jerk - but it shows that muscle memory is hard to modify. If you get new brakes of a different type, practice with them. -- - Frank Krygowski |

Same as in winter; I go to an outdoor skating rink or a safe area where there's ice and practice riding and braking on that ice. Cheers |

Seems like the dark ages now, what with 11sp being de rigeur, except for one bike with a 7sp freewheel which I guess is the darker ages. But it's a 135 mm OLN and thus has almost zero dish- same spokes since 1996 with no breakages so far. Sooner or later... Not a "disc" brake in sight in my house (except that rim brakes are disc brakes). One bike with brifters. No CFRP, no AL or Ti frames. All Brooks saddles of one sort or another. Tan wall tires, polished rims. I'm not keeping up with the times, I guess. What a Luddite! But hey, I do have one of those fancy newfangled ISIS BBs on one of my bikes. Wait, those are 15-20 years old too... I think that there are a couple of Chinese companies making 8 speed cassettes. While they don't shift as smoothly as OEM, they are a hell of a lot cheaper. Shimano HG CS-8, besides SRAM, Suntour and SunRace compatibles, are very available and dirt cheap. It's the standard thing for $400~$600 new bicycles nowadays. Any LBS which services not-quite-pro bicycles will have a stack of them in stock. Yeah, I've got some old XT 12-28 cassettes I stocked up on. I find that after a few years I break a rivet or two that holds the cogs onto the aluminum carrier. That happens before the teeth are worn out, usually. The cheaper ones might actually be better, in this regard, if slightly heavier. |

I decided not to be an early adopter. I'm still waiting to see if clipless pedals are going to really catch on. ;-) LOL! I am no longer an early adopter either. My last early adoptions were the internet in about 1992, with a Mac 512Ke and Ed Krol's book, later also Adam Engst's Internet Starter Kit. And Shimano STI in 1992 then Campy Ergo in, what, 1994? I liked Ergo better because the brake lever didn't move sideways. But I have downtube friction shifters on all of my current bikes except for the three speeds and the tandem (whcih came with STI and it seems silly to change). My wife is a much earlier adopter than me- had an iPhone, iPod, iPad, etc., long before me. She was one of the early Twitter users, also Instagram, etc. But neither of us have a Facebook account... and won't. |
