I've not SEEN a broken cassette, but I'm sure someone somewhere has broken cogs off a spider or experienced a broken pin or something.
Regarding fixie riders vs singlespeeders, I bet they're talking about the freehub, which yes, I have had freehubs fail. Usually "fail" just means the pawls got goobered up a little and bound up and the bike was unable to freewheel. All they need is cleaned and greased when this happens. I've also seen bikes with destroyed pawls and/or ratechets if the rider was a powerhouse on a cheapo hub. Higher end stuff like DT Swiss has replaceable ratchets and most reputable hub companies will sell you new pawls/pawl springs if needed. FYI: cassettes do need cleaned and inspected for wear. Depending on the cassette and freehub design, you might also find that your hardened cassette bites into your soft aluminum freehub and leaves little grooves that need to be filed down occasionally to make cassette install/removal smooth again. I count that as maintenance. |

In the age of ultra-lightweight componentry, cassettes, drivetrain failure are not uncommon:

In the old days of freewheels, I've seen a pawl break. I've never had a modern cassette fail, but I've had them groan and creak under load if they go unserviced too long, so I wouldn't say they're maintenance free. I take the freehub apart every few years, check the sealed bearings for looseness, clean everything, grease and reassemble.

Ha, center-pulls were a new improvement over the older side-pull type. The claim was that forces on the left and right pads were equal, whereas side pulls pulled only on one side. Of course that's nonsense, and center-pull brakes fell out of favor in a few years. I didn't like center-pull brakes, so I replaced the ones that came on my Gitane with Universal side-pulls, circa 1974.

Similarly for most of advancements in motor vehicles, ABS, disc brakes, CVT, etc... I'm somewhat old school, drivetrain on my bicycles are mostly 8 or 9-speed... perhalps not as fragile as the modern 11-speed drivetrain.

Too many driver's aids on today's bikes and cars! I think it allows more stupid and unskilled people on road. Whereas in previous decades, they wouldn't even have tried or would've been killed off early.
I managed bike-shop in Santa Barbara for couple years. Lady comes in and demands to buy top-of-line hybrid bike. We sell her one and off she goes. A couple weeks later, her husband comes back with bike and asks for refund. Apparently, she was riding down their street and cat runs across road. She slams on her brakes (just like on her SUV), flies over bar, smashes her face and breaks off lots of teeth!!! Ahh... good 'ol days... I miss silk sew-ups. |

Did he get his refund? If I owned the shop I might have offered a trade-in price, minus any damage from the crash.
On Shark Tank once, a guy was pushing a brake setup that had one lever that operated the rear brake. Braking force then actuated the front brake. This meant that if the rear wheel came up, there would be no braking force, and the front brake would release, making it impossible to go over the handlebar. What he didn't say was that any time braking tried to get near the maximum, when conventional brakes would have the rear wheel just barely floating and the front wheel stopping like crazy, his system would back off the front brake. This meant that it would not be possible to stop anywhere near as fast with this "safe" system. He allegedly made a deal with a shark, but I have no idea if it went past the next hurdle and actually became a contract. I wouldn't want someone failing to stop in time and running in front of a truck because of some stupidly designed safety system. |

Yeah, gave him refund minus wholesale cost of seat and bar-grips. In ‘80s, bike manufacturers started putting lawyer-lips on their fork-ends due to increasing number of lawsuits. The amount of coddling and spoiled brats have just increased exponentially since then.
What we need is a good bombing and complete destruction like what happened to Europe over the millennia; Black Plague, World Wars, etc. Kill off unfit unskilled spoiled brats and teach survivors to appreciate what they have more. |

Well that took an unexpectedly dark turn...
Also new 11-speed and 12-speed is more fragile than old 8/9 speed?? Oh lawd, keep it coming, that's too good. can't wait to see the anecdotal "proof" there... Jim, that's an interesting product. I wouldn't buy it, but I can see how it would be a fun project to develop and perfect. I'm generally not a fan of vehicle nannies, but I do appreciate the work that goes into them because I'm a nerd and that kind of stuff excites me. It's funny you mentioned a braking product today because I had an interesting ride today. I got out of work late and the rain was holding off, so I went to a close trail and wanted to rip a lap before dark (barely made it) so I has hustling to get done before I really regretted not having a light. As I'm swooping clean lines through the trees, lobbing the bike of humps, tossing it down some rocks, and generally having some party time on the descent, it occurred to me that today was the most deftly in-tune I've been with the bike in a while. I was fast and smooth and light and I never locked, lifted, or skittered a wheel under braking, and all my braking lines were committed and effortless. I then proceeded to speed home because my sensation of speed was so skewed from a fast ride that I had to actually watch my speedo... It's funny because if we all spent a little time getting to know our vehicles, we wouldn't NEED the nannies. Like my ride today, great braking is just a practiced habit. Once you get the hang of it, it becomes something you can do without thought. So while nanny brakes might be a great project on a bicycle for the sake of doing it, it might be best to leave it as just a thought experiment. Kinda like e-assist bikes. I have a very strong inner debate about them and I'm not sure how i really feel. I'm a fan of tech that progresses what we have, like hydraulic brakes and dropper posts, but I'm not sure I like tech for the sake of itself and nothing else. At what point do we go from improving the bicycle to meet a performance need and we go to making something that no longer is in the spirit of the original? Just interesting thoughts. |

Lawyers who convince clients they can get free money if they claim the problem was somebody else's fault => people who suddenly don't bother to care about their own safety => injured people, who now look for the ambulance chaser lawyers to get them free money.

Please ignore the crustiness of my bike in the following pics.
So, I'm looking for a proper rear rack with provisions for panniers as per the thread's suggestions, and I see this bolt where the pannier should attach on the brake side: Here's the same bolt from the other side: The derailleur side doesn't have this: From what I can tell, this doesn't do a whole lot in keeping the rear brake caliper in place. The two bolts on either side of it should do just fine without it. It looks like it'll be fine if I remove it, and I even took off the caliper to make sure it didn't do anything obviously important. It doesn't seem like it does to me, but more eyes on it might find something I'm missing. Am I good to go with installing a rear rack? |

Get longer bolt for brake side so it sticks out on outside about 10mm. Then mount rack and use nut to clamp to bolt. Just in case that bolt serves some function, you’ll preserve that.

So I found the weekly group ride with the local fast guys last night. A coworker was like "yeah come along, you'll do great!". Conveniently, he's one of those fast guys who has lots of sponsors and notoriety due to his MTB racing success the last few years
I got droppppppppped hardcore after about 5 miles, found another group of droppees who I was more matched with on pace and we still hauled some mail. It was a blast. I'll likely do it most weeks so I can use it as my one "high intensity" ride of the week and suffer through an hour and a half of blowing up my HR. Plus it's only 2 miles from my new house so that really helps. The group was huge and cool to chat with. Turns out there's more than a few current and former pros that show up from time to time. What a riot! 29 miles in 1:20... luckily it was fairly flat compared to everything else around here, but it was a still a suffer fest. |

I did pull. We took turns between the 5 of us. About a minute each time in the front, then rotate.

1 minute at the front is far too long if you plan to stay with the pace line for the whole ride.
Killing yourself just trying to latch on to the tail end of the pace line after a long of a pull is why most people get dropped from the pace line. High speed pace line work should be about maintaining the speed as a whole group; not how much or how long one can pull by each individual. 20-30 pedal strokes (less than 20 seconds with 90 rpm cadence) at the front of a pace line then get off is just riding smart, not hard.

And you didn't pay anything for it neither, value it as much.
But it was not your suffer fest to go through; maybe someone who doesn't like to suffer as much would value the advice more. Anyway, most serious cyclists are masochists anyway, if you can save enough energy along the way to out pace others when it counts; all the suffering is worthwhile... with or without dope.

Jokes aside, you're definitely right; shorter pulls hurt less. But roughly a minute felt right. There's no need to "out pace others when it counts" because it wasn't a race. It isn't a well regulated club or well regimented team. This is just the weekly go-fast ride for whoever shows up, which happens to be a lot of people. |

1 minute pulls may feel right to you, but if 1 minute wasn't too long, you wouldn't have gotten dropped on the ride after only 5 miles as you stated.

I didn't ask you to prove anything, doesn't matter to me if you get dropped again within 5 miles or finish the whole ride in the pack.
Just offering sound advice do you make it less of a suffer fest for yourself. But if you are such a masochist, why not strap some lead weights on your bike or wheels next time. |

Heh, heh... that's OK, common beginner mistake. faster the group goes, or closer to your FTP, the shorter the pulls. At 32mph, you're looking at 5-seconds...

Like I said earlier, A isn't wrong. Shorter pulls are smarter. I should have. I also admit it's been probably 5 years since I've been in a paceline of more than 2 people. But A continually an ass and I'm done with it. I have nothing to prove to him.
And again... not a rigidly structured ride or a well disciplined team here. Just an easy come easy go laid back fast ride. So... when we find little groups to pace in, there's no rigid agreement of "just 27.4 seconds each, boys" it's kinda a relaxed "eh I think I'm good for a bit" and fall back. Can't stress this enough. It's not a race. It's not a regimented training session. It's not a structured workout. It's just a fun ride that happens to be fast. Guys are joking and shooting the bull the whole time. |

Guys that are joking on the rides because they know better than to exert themselves at the front for period beyond their physical capabilities to get dropped within 5 miles.
More importantly on casual rides to be able to stay with the pack and joke through the whole ride. Group of five riders trying to rotate to catch the pack is working much harder work than group of 8, 10 or 20 just cruising along. As I said before, you didn't pay anything for my advice, don't make a big deal of it. You got dropped and that's how you learn the next time. |

Usually with these rides, it breaks up into different groups of various paces anyway. Unless you've got career trophies or pro-salaries at stake, you really don't have to make every training moment count for maximum benefits. I was trying out for Olympic Trials in 1994 and every single ride was life-or-death to make it count. After Trials, life just seems so much more relaxing and easy.

You are 100% insane for ever getting to that level. I mean that in a good way. At the end of the day, if it's not about having fun, why do we do it? That's why I stopped playing soccer. It was no longer about having fun. It was politics.

I like bicycles . All sort of bicycles and have commuted car free for a number of years. Raced , club rides, toured. Mountain bikes BMX you name it. I even got married on Bike tour Colorado after meeting my wife on a bicycle tour in Maryland. So I can say I’m a bike guy. Though for the last couple years I have been motorcycles and scooting more than cycling mostly because I had to have my knee replaced. But I still love bicycles. Today I spotted a new bicycle . I won’t buy one. Because I just don’t have the money. But if thing were different and I needed a pit bike . This would be it.

With a knee replacement, is the limitation more of a strength issue or pedaling frequency issue?
Depending on the challenge, there are some different ways you can make it easier pedaling for your knee. Personally, I prefer a hub-driven electric bike over pedal-assist-type electric bike. My last electric conversion was capable of 40+mph and nearly 30 mile range on battery power. |

I used to ride 15000 miles a year. It’s more of
Just not wanting to ride. And moving away from the place I really liked to ride. Iowa is nice and very bike friendly. But I think it’s not that I have moved on.
