CopperHound posted:Thomson seatposts like cracking up there and they will tell you to pound sand because you didn't use a torque wrench. (Nobody uses a torque wrench for their saddle clamp) Why are Thomson posts so highly regarded? Their hardware is soft as pudding, they seem to popularize zero offset posts that help virtually no one with fit, and their setbacks are so goddamn ugly. Plus, their collars suck too. No consistency on sizing at all. Are branded seatpost shipping bags what people think is worth the price of admission?!?

kgibson posted:Update about this mystery noise: seems to have been loose rear wheel spoke or spokes. I retensioned them all, added a dab of lube to points of intersection, and had a silent ride today. Hopefully that'll be that! Where's my certificate of appreciation? ;D As for seatposts, when I was trying to find a post for my Rockhopper -> gravel build basically everything I read said that except for some very edge cases setback posts don't make sense. TT's and weird fit situations were the common exceptions. Got any examples of more "general use"? I'm genuinely curious! Edit - stuff like this https://analogcycles.com/zero-offset-seatposts-make-zero-sense-mostly/

jammyozzy posted:I feel this post, I'm pretty tall with long legs so by the time I've got the saddle high enough of a lot of frames I'm now stretching for the bars. The only way I've found to fix it is a straight post with the saddle scooted forward, but I was considering a forward post on one of my bikes. Isn't this like the classic "don't adjust reach with saddle setback" thing? I.e. change stem??

Literally Lewis Hamilton posted:6/7/8 chains are cross compatible. Just make sure you get a chain that is long enough for how many links your current chain is. You’d need to cut the chain down to be the same length as your current chain, presuming it’s the right size. Yes and not sure how much you already know but you'll need a chain tool to shorten the new chain to match your old one, and maybe a set of quick-link pliers to connect the new chain up when the length is set. You might be able to get away with snapping the quick link in w/o the pliers (set it, and then stand on a pedal while stationary to lock it) but if you ever want to take it off for cleaning or maintenance then definitely get a set of pliers.

How did Thomson get such a solid reputation with such poor quality? I bought a seatpost clamp from them that was at least 3mm wider in diameter than advertised. A $5 no name one was within 0.1mm of spec.

Aero737 posted:No coop that I'm aware of and not too attached. I picked it up for $100 and I wouldn't want to put more than 60 or 70 into it. I'd be surprised if you could even do the brake changes you want for under 100. I don't think the derailleur jockey wheel missing tooth really matters. Throw a new set of brake pads on it and see if it stops to your liking. Clean the braking surface too. Kool-stop salmon pads are well regarded I believe.

EvilJoven posted:Not if it was at just the right point to snag and cause the pad to basically bounce along the rotor, it could very possibly be that, and only triggered when the frame flexes a certain way. It's worth spending the few minutes and no cost to check. My Sram rear brake squealed at low speeds. Swapped pads w the front, problem solved. Cleaning rotors and pads did not. FWIW

Doesn't help in the above issue, but my recent discovery was that centering calipers is best done with light to medium pressure on the brake lever vs hard. Tighten the bolts very lightly then switch back and forth between them to snug up tightly.

The important parts re:replacing like for like are: Cassette vs freewheel (that's a freewheel) The number of cogs The number of teeth on each cog (particularly the smallest and largest - part will be listed as "XX-YY" where XX is the number of teeth on the smallest and YY the largest) If you're replacing the freewheel you should get a chain checker and find out if the chain needs replacing too - a worn chain will skip on a new freewheel. Chainring(s) on the crankset too...

Since the binding is asymmetrical perhaps the BB shell needs facing??

I believe aluminum will form an oxide layer and therefore protect it from deeper corrosion (unlike steel). So I think it's just up to you on aesthetics.

You only need a patch if the hole/cut is so big that you have to keep the tube from escaping when inflated. On tubeless it's those plugs/strips that come in when the puncture is too large for the sealant to work. The only road tire gluing I'm aware of is tubulars...

On the tire hole question you can "boot" a big hole as a field repair with a dollar bill. The fibers are strong enough to prevent the tube pushing through. The other benefit to tubulars is that you can ride on them even when they're flat, hence the use in racing when the team car/pit is far away.

Lex Neville posted:Apologies for the hastily taken video, but does anyone know what could be causing this clicking sound coming from my kickr core? I took the cover off to see if anything was interfering with the belt, but there doesn't seem to be. It occurs under and without load, though it is particularly noticeable at a lower rpm. It also doesn't matter whether the cassette is on or off, the QR skewer is in or out etc Seems to be tied to one revolution of the input shaft or idler. Unfortunately I'd guess that's internal to the unit. Warranty?

Honestly bikes are great because they normally tell you what maintenance is needed. Anytime you remove/reinstall anything use a touch of grease (if applicable of course). Wax your chain every 2-300 miles. Check brake pad wear/debris in the pads. Tire wear (front to back, new on front). Spoke tension/cracks at nipples. If everything is running quiet and doing what it's supposed to do you're likely in good shape.

wooger posted:And the unexplained creak under power on my bike that has stayed unchanged through a couple of weeks of my own diagnosis and 3 separate trips to 2 different bike service places is telling me what exactly? Hey, I did say "normally"... My sincere condolences - I chased a creak in my road bike for 6 months. Disassemble everything, clean/grease/tighten to spec, even tried new wheel hub bearings. Ended up removing and reinstalling the BB (didn't really even clean it as I'd had it out only a few months prior to try and fix the creak) and lo and behold, gone. Could yours be a cracked frame/unfaced BB shell?
