They are a HUGE improvement. I started with Time Equipe road pedals back in the late 1980s, early 1990s. Same ones Lemond used. Interestingly, the guy who set our club's record for club mileage (11,000+ miles of club rides, not counting his individual rides) just got a new pair of shoes for riding. They're ordinary New Balance sneakers. He rides using toe clips. There are also the occasional barefoot marathon runner and US football kicker. They are outliers. One of our club riders mentioned that most falls on bicycles stems from people not getting their feet out of clips rapidly enough. So he reverted to flat pedals. Now he cannot keep up on any climbs. And people with training can get out of pedals just as fast as he can step off of a flat pedal since they are ready to clip out when the conditions warrant care. Can’t say I have found any performance difference at all, I used clipless for a few years on my first road bike, was fine, never struggled to clip in or out or had a clip less moment but I never loved them. Few years back bought a CX bike for hacking about the woods plus road and put some MTB flats on, and used my MTB flat shoes, ie pedals with pins in, plus shoes with soft tacky tread. In short with proper flats you can’t slide the shoe but have to lift to reposition, unlike the road flats which are frankly terrifying slippy. I’ve done 100+ miles on them, climbed up big mountains, tackled seriously steep climbs etc. I’ve seen opinions dressed as science with huge gains for clipless but proper stuff the gains is marginal, apparently. Which certainly echoes my experience. Interesting the pulling up, gain is very difficult to prove. Roger Merriman Yesterday, when the pedal stripped out of the crank, I pedaled a mile with on leg. Try that with flat pedals. Wow. How did the pedal strip out of the crank? I was just riding along and the pedal started rocking. I immediately turned around to see if I could make it back but 10 miles from home the pedal, threads and all simply pulled right out. Pedals, as you know, are "British threaded" so you only have to tighten them to "snug" so I tighten them in with an Allen Key to keep from overtightening them and pulling threads. I stopped using the large and heavy pedals wrench long ago except to pull a pedal off. But this is the first time I can remember a pedal stripping out of a crank. The only cause I can think of is that the thread diameter on the pedal was undersize and the top of the threads on the pedal were cut flat on top. Or you under-tightened the pedal, which is the most probable explanation. It's 30-40nm torque -- which is more than "snug," which is IMO about 12-15nm like Shimano crank bolts. Jay, pedals are English threaded and under force they tighten. I took these pedals and cranks on two hard climbing rides so if they weren't tight enough before they were tight enough after. I have never had any problems with FSA cranks and Look pedals. Looking at the threads on the Rock Bros Keo substitute you can see that the threads are not badly made but I'm willing to admit that rather than the pedal it might just as well have been the material of the crank. I just measured the threaded area OD on the Rock Bros pedals and it is pretty regular 0.55" which is .0125 smaller than the 9/16 but it is the same measurement as Look pedals measured in the same manner. Did you tighten the pedals to recommended torque?* If not, it backed out because the pedals were under-torqued.* If so, then you have bearing binding.* The question now is if you have ruined the pedal threads and need to replace the crank. Can't those be Helicoiled? In theory but the usual pedal thread repair is a 5/8" full sleeve: http://www.yellowjersey.org/photosfr...ast/ped_58.jpg Ah. OK. -- - Frank Krygowski |

Nobody appears to be lamenting the demise of chromed steel rims. In the ****ed up world of retro bikes I have seen a few at work with chromed steel rims. Now those don't get ridden in the rain or I wouldn't be seeing them! O RLY? From 1992 to 1995 I rode my Sparta Cornwall bike to work, every single working day, around the year. https://www.mystrobl.de/Plone/radfahren/bild12a.jpg Indeed, these are chromed steel rims. Any idea why there wasn't any problem with that, huh? The cloggies get a lot of rain and figured out a better way do it! Sorry about the picture quality, that picture was taken using an Apple QickTake camera, in 1995. Imho, the two biggest advancements to modern cycling, the alloy rim and bike lights. Hand up who remembers cycling home in the dark on a rainy night? NiCads suck. Sure. So do lead/acid batteries, for example that gray piece marked "friwo" in the picture linked below. https://www.mystrobl.de/Plone/radfahren/technik/komponenten/licht/lichtc1.jpg/image_preview Or bottle dynamos, like that one. It sucked. https://www.mystrobl.de/Plone/radfahren/technik/komponenten/licht/P1050501a.JPG/view.html Those union turbos worked no better than Nordlichts, which I grant you was a step up from a any other bottle dynamo (I owned two Nordlichts) but the hub dynamo was the answer, and arguably (I don't think so) the LED light. But somehow, most of this stuff worked good enough to server my well for many years. A few expensive parts did not. For example that one: https://www.mystrobl.de/ws/pic/such/DSC04651.jpg. Do you know what it is? Yes, I have one if you want it. It fits to the rear triangle behind the bottom bracket and scrapes crud of your tyres :-) I'm not sure how far back "modern" cycling goes, but I would add gearing to the biggest advancement category. Front and rear derailleurs and a means to shift into the various rear cogs and/or chainrings. I agree. I've read old tales of touring with three or four speed hub gears. Walking up any significant climb was standard procedure. People still do that nowadays. Bicycles got lighter with alloy components, rims, frames, handlebar, this made it easier to push. I cycled to school on a heavy Rabeneick bicycle, using a 3 speed hub (Fichtel&Sachs Torpedo). Riding home (6%, about 120 m up) wasn't easy. But pushing that bike would have been even more strenous. Before derailleur gearing, I think pneumatic tires were the biggest advancement. What about better brakes? Since derailleur gearing I think we've been chasing ever tinier marginal improvements. Sure. But some of those marginal improvements are nice, nevertheless. The most modern "improvements" are very underwhelming. We're now down to "Ooh, I don't have to move my finger as far to get a gear change! And it cost me only a couple thousand dollars extra!" My current custom made road bike, built in in 2010, has Shimano st-6703 Ultegra Dual Control Shifters. I like it. They aren't without fault, the mechanics are somewhat fragile, changing gear wires is somewhat difficult, but overall, these offer significant benefits compared to downtube shifters. I still have my old read bike, a Panasonic PR3000 bought in 1995 https://www.mystrobl.de/Plone/radfahren/pict2439.jpg/download and keep it as a backup and for indoor training, but I prefer to ride the newer bike. It wasn't that expensive, either, about EUR 1400 (~ $1700) in 2010. One of my sons bought a similar bike less than a year ago for even less money. If i was asked to list improvements, I'd name hub dynamos, led lights with free-form reflectors, clipless pedals (esp. SPD), plus all those tiny improvements which aren't really exiting and less observable - better brake pads, better alloy, better tires, better handlebar tape, ... Clipless pedals, forgot about those, yes I'd add them to the list. I use the M324s on all my bikes, but tbh I rarely use the clips these days. |

You remind me of a fond bike-wrenching memory: In college I worked a few stints at a local shop, mostly assembling new bikes for the Christmas rush (a thing that used to happen in the bike biz, but does no longer, I'm told). One day a Prof from my school came in with his three-speed, maybe a Raleigh.Â* I recognized him, though he didn't know me.Â* His sadness was palpable as he held a detached pedal in his hand.Â* "I think I broke it, is there anything you can do? Can it be repaired?" The steel crank threads were rough, maybe damaged by the pedal coming out, so you couldn't screw the pedal back in by hand. I ran a pedal tap through the crank arm, probably in from the back side; put a bit of oil on the pedal threads, in it went, and I tightened it thoroughly.Â* I'm sure I checked that it was spinning freely. You would have thought I had parted the Red Sea.Â* He was so delighted, and he made me feel like a wizard.Â* I don't know what the boss charged him - I was just a temp wrench and prices were above my pay grade - but he came back after paying and stuffed a five dollar bill in my shirt pocket, which was a fair bit of money back then. We MEs would say "He was probably an Electrical Engineer."Â* ;-) Or maybe English? Once I noticed a faculty member's bike parked in a rack on campus with the front quick release not clamped, but instead screwed down by hand. I tracked the guy down and gave him a lesson on quick release levers. He was very grateful. I found him in his office in the English department. The lost-pedal guy was from the Poli Sci department. Later I took his intro class on American ?Government? ?Political history? and enjoyed it. Learned a lot about the accomplishments of the various presidents and one hundred landmark Supreme Court decisions (we had to learn one-sentence summaries of the 100 by name). Mark J. |

All the local shops around here had bikes pushing the $10K mark on the shop floor before the pandemic, and those are all sold out now. The only stuff now in the shops are odd sizes or fugly colors, though one shop as a few super-high end Specialized MTBs. Currently, a Specialized S-works SL7 Tarmac or Roubaix with DI2 in this area goes for about 11-12K depending on a few options, and people who have bought them are told delivery wouldn't be until the end of summer, and yes, I know two people personally in that situation. People spending that much money on a bike around here tend to go to one of the high end shops where they can get a fit. I'm actually in the market for something in the 10K+ range, specifically looking at a SL7 Tamac, I can't even get an appointment to meet with the fitter until July, and I'm probably going to spend well over 12K by the time everything is said and done. Not that it really matters, I wouldn't be able to take delivery until christmas at this point. The most I've paid for a new bicycle was about $300 in 1984. ($758 in todays inflated dollars). My first real bike was a Basso Gap in 1984. I paid $750 for it. I haven't bought a built-up road bike since then, preferring to build my own, but bought a Merlin Road frame in 1989 for $1200 with a Campy Chorus 6 speed component group, can't remember how much I spent on the parts. My current race bike is a Scott CR1 with SRAM Red and Zipp 303wheels. To replace that now is probably $8k minimum, (though I think I spent just over 5 for all the pieces), which is why I'm going all out for the SL7 Tarmac. I have bought a few mountain bikes completely built, the last one being a C'dale Habit 3 in 2018. It was a leftover 2017 that retailed for $3200, but I got it for just over $2K.
