Hello, I recently got a bike new in a box, it came with tektro hydraulic brakes. The rear brake is exactly how I would expect based on motorbikes and hydraulic braked bicycles I've ridden, basically instant response. The front has a persistent 1-1.5mm of pad clearance on the inboard pad that I can't seem to get rid of. I've played around with centering the caliper dozens of times (it's mounted on an adapter with cone washers under the bolts), I've found that even if I can get it so the clearance is an even .5 mm on either side, after riding up and down the driveway and using the brakes a couple of times, it always returns to the usual situation of a big gap just on the inboard side. I don't think it's an issue of pad alignment because I can pull the lever, release and watch the piston move right back until no part of the pad is touching and keep going until that big gap forms. Is this a bleeding issue or is it just meant to be that way for safety? I don't normally get hung up on stuff like this, but it makes for a really vague and unpredictable initial bite, especially compared to the rear, it really saps confidence on loose surfaces.

Can I use a 29" tube in a 700 tyre, provided the profile is the same? Or are the diameters different? I can't trust anything since I discovered the 'sizes' are just arbitrary and not reflective of the actual measurements at all.

Is 27" the same as 27 1-1/4? That's what all the old road bikes seemingly came with here.

Looks like 27 x anything, in the context of old road bikes, is 630mm ISO. What makes this initially really confusing is 29" MTB tyres that are in fact just wide 622.

I got given a rusty 80's (I think) road bike and it's got a bunch of cool details I haven't seen before, because I know nothing, including these sweet little axle adjusters built into the frame: I get what they do but what are they for?

If you had the choice between two functionally identical (but differently colored) 105 LH brifters would you go for the one that has a hosed up looking lever but is mechanically perfect, or would you go for the great looking one that has a missing section of plastic shield so the mechanism is theoretically slightly exposed when you brake or shift (this bike won't be used in the rain). The levers unfortunately don't interchange despite looking the same from the outside.

It's a little plastic cover to the rear of the lever that covers the ratcheting mechanism, it might be replaceable but would involve dismantling the part you shouldn't dismantle. I don't think it was ever close to weatherproof, it's more a cosmetic thing. I think I'll run the good looking but broken one.

Is there a rough mileage/hour estimate of how long tape 'should' last the same way we can estimate chain life? Is there a big functional difference between cheap poo poo and fancy stuff?

Is there a difference between alfine and Nexus that's more than just more/less fancy than? Is it that it's compatible with brifters or something? I have a Nexus 7 speed and an old rsx 7 speed brifter, is it even worth trying to make them work together? Obviously the shift pattern will be reversed but that's fine by me.

TenementFunster posted:how much of a boomer/fudd am i for thinking electronic shifting and disc brakes on strictly road bikes is just a way to soak dentists for couple extra grand? have disc brakes suddenly gotten a lot better/have considerable advantages over double-pivot brakes in the last few years? Disc brakes rule and they should be on everything, cable or hydro, whatever they are objectively better. Electronic shifting with software updates and all the other modern tech bullshit attached is a revolting concept and you'll take my lovely cables from my cold dead hands.

VelociBacon posted:The jagwire enjoyer Had to google, looks expensive, regular old Shimano will do me. Literally Lewis Hamilton posted:Electric shifting with rim brakes is delightful though Each to their own, good rim brakes work fine but discs are preferable for me. I don't really see the point of electronic shifting, seems like a huge increase in bullshit for a tiny weight and appearance gain. I also like the mechanical positivity of changing gears with a cable, I think it's analogous to a car with a clutch and gear shifter vs a button shifted auto.

kimbo305 posted:Rim brakes teach you how fleeting beauty is. You set up your pads floating less than a mm above perfectly true new rims, and then they rub the moment your slam into the first crack in the road. It's just an endless dance between a desire for as little play as possible vs a desire to not hear irritating rubbing. And that's assuming you don't have to actually take the pads OUT, yes let's just have 3 axes of adjustment all controlled by the one lovely lock nut where, again, you have to balance getting the pad perfectly orientated vs tightening it enough that it doesn't lose position and jam and kill you.

Literally don't care if it's better in some way, I don't want electronics on my bicycle. sweat poteto posted:Unlimited tire size and space for fenders is good enough reason to use disc brakes. Zero maintenance and immunity to rain are just bonuses. Fine by me! Havana Affair posted:Jan Heine wrote sometime ago that he predicts the enthusiast field is gonna split between electronic shifting or special down tube friction shifting (guess which he's selling). I tested my friend's desmodromic Cyclo rear derailleur from the 1940s and the shift feel is superbly light with no spring in the RD to resist so Heine may have a point here. I think six months after this hypothetical split someone will just start making brifter/toggle adapters for them, down tube shifters suck. There is a balance to be struck between practicality and simplicity, brifters aren't a particularly complicated device but they change the bike completely. Yes I am currently hoarding old brifters why do you ask?

While we're here, is there some specific reason to run 650 instead of 700 wheels on a road bike? Like is it a size or handling thing, or is it more an aesthetic or personal preference thing? I've noticed that at least with mtb's it seems to be common that the smaller sizes of a bike with 29's will come with 27.5 wheels instead and this makes sense to me, but I've seen some pretty small road bikes that still have 700 wheels.

That makes sense, does it mean that your bike has really big tyre clearance? Do they also have really long reach calipers or is that a wheel specific thing and you aren't really meant to swap back and forth?

Dog Case posted:Mine uses discs and being able to swap easily is a selling point. They sell wheel sets in either size that include a cassette and discs and i think they even sell the bike with both sets of wheels included. Right I forgot discs on road bikes are a thing  That honestly sounds rad as gently caress, much less compromise for whatever you're doing.

Reading all the above, does that mean that I could theoretically get an elderly, rigid 27.5" MTB and fit skinny 700 wheels? Or would they have to be 650?

CopperHound posted:Indexed rear shifting has been a solved problem since the invention of hyperglide. This but on the down tube seems super common on 90's road bikes. Unless that's  I've no idea how you're meant to use normal non indexed friction shifters on the DT properly, I found myself constantly looking down and wobbling around with one hand on the bars. When they're on the bar like an old MTB it's a little fiddly but fun, on the DT they just feel super far away and awkward to me.

Toe Rag posted:The mounting seems a little wobbly? I think this may be the problem, actually. It's wobbling around causing problems when it used to be only on bigger bumps. I've dealt with basically this exact problem on a couple of old bikes and yeah, the factory grease turns hard and makes the ratcheting mechanism skip instead of catching. It's all made of metal and you can take things apart, immerse the relevant parts in solvent then lube it.

Keeping a shift cable and a master link in your bag is a no brainer imo. And a multi tool with a built in chain breaker/riveter.

My commuter has a hub gear  but I also live in a place where winter is just slightly colder and much wetter than summer so I just have to make sure there's enough oil and not too much grit on the chain

I want to switch to immersion waxing my chain but I'm finding it surprisingly difficult to find the stuff locally. Anyone know where I can get it in NZ? Or alternatively a non-brutal shipping option online. I'm prepared to do it diy with paraffin wax but want to avoid that if I can. E: would this stuff do the job?
