Do you mean determine what model a component is? If the parts are original to the bike, you can look at catalog specs, or other sources that’ve aggregated the specs. https://www.feltbicycles.com/documents/archive/2015_FELT_Catalog.pdf pg 144 has the spec. You should confirm with the picture, first. Multiple places I found have the brakes as Tektro Miras, so maybe your bike has some aftermarket parts. In those cases, a picture and asking here might be your best bet.

a loathsome bird posted:What do people think about chainstay repairs on steel frames? My Xtracycle Free Radical is cracked on both sides past the dropouts (front of the bike is to the left, the crack is on the cargo extension part of the chainstay). I got a quote locally for $160 which seems fair but not sure how wise it would be to repair vs replace, especially with a toddler on the back. I had a chainstay replaced on my tandem. Replaced the whole tube rather than just re-welding.

Are the Novatec SL hubs that Light Bicycle use good enough to be worth rebuilding a wheel around? I bought a second hand front wheel and the seller threw in the rear as well because it had a damaged rim. I can get an exact replacement from LB if the spokes are ok to re-use.

My rear rotor had as loud as the second coming of Christ, but I ignored it because it’s the rear brake and it’s never rubbed the pads when my hand was off the lever. Suddenly it’s quiet. Too quiet.  I’m just going to continue ignore it. I’ve always been careful around it, but maybe it was contamination somehow.

I have a nice 10 speed Campagnolo group that I was thinking of using on a bike with disc brakes It'll be mechanical, obviously, since 10 speed Campy is so old Are there any compatibility problems that I need to worry about if I use TRP Spyre brakes? I've got a lot of road bikes but I'm new to disc road bikes

Campy does have a different, shorter brake pull. It might or might not be a problem for Spyres. Here's the Paul Klamper arms for normal road vs Campy:  So if it doesn't pull far enough, you might have to choke up on the Spyre brake arm a bit.

i'm using a surly disc trucker fork on my build and i noticed where the front caliper goes there is no threading in the two mounting holes whats the deal with this (i was also confused because through the hole to the caliper is like 40mm distance very long) i'm just used to seeing threads in brake mounting holes nevermind i guess it will all come together when i get the flat to flat mount adapter thing  is what its supposed to look like, helped me out shortly after makin this post Turmoilx fucked around with this message at 03:34 on Aug 26, 2023 |

What's up? I'm that person. I feel like I opened a door to needing to adjust my brakes a lot more often with that one. It's pretty annoying! I had some chatter or something on the front brakes on my last right so I looked at my brakes and both front and rear looked like the disk to pad spacing was no longer as even as I had set it up. One side was contacting the rotor first and then flexing the rotor a little even. The assemblies were still tight on the frame, so that wasn't it. I made adjustments so that I didn't notice and rotor flex and the pads ~evenly spaced from the disk so I'm hoping that works for another bit. Is it normal to need to make small adjustments to your brakes in like 30-50 mile intervals? How often do you have to adjust your bike brakes? This is like the first time I've ever had to worry about them.

TRP Spyre C. I went for a quick ride yesterday and I had to readjust the pads right before because it's as if the positions just changed while sitting. It's interesting though I was stopped at a light and then squeezed the fronts while watching and at 1 light they would deflect the rotor to one direction and at another it was like they were roughly centered, so there was no disc flexing. It's really odd. The chatter or pulsing in the front was much less but I feel like I still felt something. So I think my quick adjustment before did something.

Hotbod Handsomeface posted:at 1 light they would deflect the rotor to one direction and at another it was like they were roughly centered, so there was no disc flexing. Do you always lean the bike at the same angle? Does the Disc Trucker have thru axles? If yes, do the same squeeze test all the way around the wheel at regular intervals, using the valve stem as an index. See if the rotor wanders left-right. If no, see if the wheel is tight in the fork. kimbo305 fucked around with this message at 18:53 on Sep 1, 2023 |

I have Spyres on my bike with QRs, and they can be a little finicky but not that finicky. They were a little frustrating to learn the quirks at first, especially since I have low tolerance for noise/vibration and like really tight and responsive brake feel, but I've got them figured out now and think they are pretty great for what they are. Because they are mechanical cable-actuated, they are not self-adjusting so as the pads wear you do need to adjust them to take out cable slack, but not every 30-50 miles. They just need a half turn of the barrel adjuster every few hundo miles to keep them nice and taught. Assuming the caliper is mounted and aligned well on the fork/stay, then here's a few things I can think of. Is your bike QR or Thru-Axle? The downside of QRs and disc brakes is that each time you loosen and tighten the QR the axle (and therefore the rotors) will sit in the dropout ever so slightly differently. Fractions of a millimeter matter in this case. If you do have QRs, are you certain that they are secure enough? Even a little bit too loose can allow micromovement of the axle in the dropout and change pad-rotor alignment. How old are your cables? If they aren't moving completely smoothly maybe there is friction there preventing the pads from retracting consistently and fully? Much less likely would be a loose rotor bolt or something weird there, but again that is probably unlikely unless someone has fiddled with them. Also the type of pad you're running can absolutely affect noise. The metallic pads it came with would honk and vibrate horribly if wet or dirty or even the slightest bit misaligned (and had poo poo brake feel), so I switched to resin pads and they don't make any noise and feel better, too. Trade off is they don't last as long, I get about 1500 miles out of a pair of pads since I live in a rather hilly region and am not afraid to brake hard. But they are like $10-15/pair for Shimano B01S pads and take 10 minutes to swap out so that's fine with me. I also put a tiny dab of copper grease on the back of the backing plate which may or may not help reduce pad vibration and movement within the caliper, but I feel like it helps so I dunno I keep doing it, YMMV. Just don't get any on the pad or rotor. Guinness fucked around with this message at 07:57 on Aug 31, 2023 |

Found my crank arms creaking when I took my bike out for the first time after a ~120 mile ride and ran over to the bike shop and they said it needed to be tightened. They still creak after tightening and I'm thinking they got loose and the threading might be hosed. Haven't taken them off yet, but is this going to be a problem with the crank arms, the BB or both?

Mauser posted:Nah this is me standing on the pedals Usually it's not the threading that gets hosed but the actual mating surfaces of the crank and BB that get damaged when a bike is ridden around with a loose crank. If the crank was actually loose and they tightened it, and it's still creaking, it could be the BB creaking or the crank/bb interface creaking. I say it could be the BB because it's possible your BB is just shot and you noticed the creaking, and incidentally the cranks were slightly loose but this wasn't causing the creak.

Girlfriend has an old japanese made Raliegh that's been her toodling around the city bike for years. She left it outside last winter (!!!!!) and I finally got around to looking at it. Cranks were completely seized, but it's just old cottered cranks and normal 1/4" bearings. It's going to get a nice chain soak, a little cleanup, new bearings and cotters and it'll be okay.

Yeah threads seem fine. I tried a new screw just for fun and both original bolt and new one, when I tighten it to around the right amount of torque, they'll do a click/pop and jump forward on the drive side. I think I'll try replacing the BB first since that's the cheapest option. I wasn't able to get the crank arm off, so I guess I'll finally pick up a crank puller and a new BB once I get back from work travel with that all that per diem money  Mauser fucked around with this message at 16:55 on Sep 1, 2023 |

It’s not interference from the jockey wheel, right? Twist the B screw in some and see if the noise goes away. Sometimes the tension is fine, but the pivot needs oil.

That's a better upgrade before pads IMO. I would also make sure you're using the metallic version pad for whatever system you're using, but if you're riding an ebike it probably came with those already. If you're not having issues with fade or power I wouldn't change anything!

I don’t think pads make much difference to stopping power, they’ll all provide enough force to lock your wheels reet quick. Resin pads tend to be quieter but last less well than metal. Plenty of people I know changed to off-brand resin pads during COVID and had no issues. The one exception is when you’ve contaminated your pads. For heavy riders potentially doing a long descent, heating the rotors / calipers / brake fluid is the most significant problem. That can cause warping rotors, and worse can boil your brake fluid and make you lose stopping power entirely. Bigger rotors helps, dual pot calipers helps, but if you just brake in short bursts, use both brakes and don’t drag the brakes down a long hill you’ll have no issues. I feel strongly that brake pads with cooling fins attached are nonsense. They make it harder to fit the pads and do very little else other than cost more. I have them on 2/5 bikes though somehow.
