That, for me, is almost reason enough not to use the brakes!<br /><br />Although I am a bit more fastidious than most people about maintaining my bikes, I don't want to use overly fiddly equipment. When it's a nice day, I'd rather be riding than fixing. Also, I like equipment that's forgiving. For example, I want brakes that will still work even if, say, a spoke breaks and a wheel goes out of true or a derailleur that will still work even if the cable needs adjustment.Justine Valinottihttps://www.blogger.com/profile/10852069587181432102noreply@blogger.comtag:blogger.com,1999:blog-8908461644259659419.post-89316624672646325682016-01-25T05:27:22.977-08:002016-01-25T05:27:22.977-08:00My main complaint about disc brakes is the tight t...My main complaint about disc brakes is the tight tolerances involved. It's so bad on one of my bikes that there's no room between 'able to pull the levers to the bars' and 'squeals constantly,' even with caliper realignment. Rotors are easier to bend that properly-built wheels and don't have to bend very far to scrape the pads on every rotation.<br /><br />I'm replacing those Avid BB7s with TRP Spyres, which I've had better luck with on another bike.<br /><br />Also, the need to use needle-nose pliers and Torx/tiny hex wrenches seems odd.Neil E.

I caught her cheating, and trying to help another student cheat!)<br /><br />Your comments about Heine's explanation of "planing" make sense to me.

One of the former Sony CEO's, in his autobiography, wrote about how he (when he was a vice-president) and a fellow vp would often be in disagreement about most issues. This other vp was bothered about this, and brought it up. The future CEO's response was, " well, if we both always agreed, why would the company need both of us?"<br />As far as the gospels, I find it hard to believe that otherwise intelligent people would have such an irrational belief in some magic invisible guy up in the sky, even when he fails to solve any material problems in the world, or lets bad things happen to good people, I do admire Pope Francis, though, but primarily because he reflects the real teachings of Jesus, not those perverted by the fanatical Paul, upon whose letters much of the Catholic Church is based, despite often being at odds with Jesus' principals. So I hope I haven't offended your religious sensibilities!<br />I agree that Compass stuff is quite overpriced. I'm used to buying Vredestein TriComp (now Senso) tires, which normally go for about $70, for $32 when they're on sale. I'd like to try the Compass 700x26 extralight tires to see if they do make a difference, but NOT for $75 a shot! I usually buy his more useful books when I can get them at distressed prices. Yes, and the current Rene Herse bikes are merely Boulder bicycles, no particular cache there. <br />I have a hard time with his idea of "planing." I've read the article he linked me to regarding the physics behind it, but I remain unconvinced about how rotary crank motion can be stored and converted to forward motion of the bike. I am more inclined to believe that "planing" has more to do with using wider tires with thin sidewalls and lower pressure, where the tires get compressed at the start of the stroke, and somehow return "power" as they assume their regular shape. But I am not an engineer or physicist. I think power is lost as the tires compress, much like a mtb with front suspension that's not locked out.<br />I do admit to reading BQ, though.

And you're right about the thinner sidewalls of today's rims: That's where a lot of the "weight savings" really is.<br /><br />About Jan Heine: I don't take his word as gospel, any more than I take, well, the Gospel as gospel. (I hope I didn't offend your religious sensibilities, if you have any!) I do enjoy looking at BQ, though, as it offers articles and photos of things not covered in most cycling magazines.<br /><br />(I must say that I have issue with him and Compass Cycles appropriating the Rene Herse name. That's one reason why I haven't bought anything from Compass yet. Plus, I think a lot of their stuff is overpriced.)Justine Valinottihttps://www.blogger.com/profile/10852069587181432102noreply@blogger.comtag:blogger.com,1999:blog-8908461644259659419.post-86893241967574542932015-10-06T10:26:01.216-07:002015-10-06T10:26:01.216-07:00I ride road bikes exclusively (mostly a fixie), an...I ride road bikes exclusively (mostly a fixie), and I've been experimenting with a front disc brake for the past couple of years. I also read BQ, and I really think that what Jan Heine says needs to be taken with a heavy grain of salt. My experience has demonstrated that a good front disc brake is far superior to a good rim brake in terms of power, modulation, and reliability/durability, and especially in the winter. A front caliper will wear out the front rim, especially in the rain. Rims these days are being made with thinner sidewalls, so where I used to get three winters out of an aluminum rim (700C), I now get maybe one or two (I ride lots in the winter). As the front clincher rim wears, the sidewalls start to splay out, leading to "grabbing," irregular brake feel, fork "juddering," and eventually catastrophic rim failure. But usually you've replaced rims before then! On a disc front wheel, the rim never wears out, and a good metallic compound set of pads will last over 3,000 km. Organic disc pads are useless, they'll go maybe 500 km in a dirty,wet environment. I have used mechanical (BB7) and hydraulic (TRP Hydrex and Shimano 785) road discs and have been happy with all of them. I'm currently using a 785 caliper with TRP lever on my fixie this winter, and I'm having a new road bike built that will use a TRP Spyre mechanical caliper with Campag Ergopower lever. But, like my fixie, the new geared bike will use a rear caliper for weight savings, and because I hardly touch the rear brake when I've got the disc in front. So, yes, I think road discs are - if not mature - useful now, especially if you ride all winter.Attilahttps://www.blogger.com/profile/03811795451584812683noreply@blogger.comtag:blogger.com,1999:blog-8908461644259659419.post-43505699271605877042015-10-05T12:35:11.977-07:002015-10-05T12:35:11.977-07:0050 Volt--I probably won't ever buy a downhill ...50 Volt--I probably won't ever buy a downhill bike, and it's not likely that I'll buy a high-performance mountain bike.

If disc brakes make sense on any kind of bike right now, it's probably a full-suspension mountain--or downhill--mountain bike, especially if the wheels have through axles. Disc brakes might also make sense on a non-racing tandem bike. But for any other kind of bike, disc brakes--at least in this stage of their development--are unnecessary. I'm not sure they'll be of any benefit on road bikes.Justine Valinottihttps://www.blogger.com/profile/10852069587181432102noreply@blogger.comtag:blogger.com,1999:blog-8908461644259659419.post-12713043263026119352015-10-03T21:26:29.456-07:002015-10-03T21:26:29.456-07:00Good post, Justine.
