What's a good vendor for inner tubes? I need to replace a Schwalbe #19 tube that fits a 700x48c tire. Looking for something heavy duty, since the last tube developed a pinhole leak on the seam after about 200 miles.

If I have 700x48 tires, am I asking for trouble using a 700x28-35 tube?

More inner tube woes. The other week I got a pinhole on the inner seam of my rear inner tube so I replaced it. 50 miles later, I got a pinhole on the inner seam of my rear inner tube. Sounds like an open and shut case, right? I thought so too, but the pinhole on the new tube is in a different place. Old puncture (tiny hole on the seam near the scotch tape), at about the 8:00 position relative to the valve:  New puncture, about 2 spokes counter-clockwise from the valve:  Same new puncture, flipped around to show the other spoke hole where it might have been if I got the tube flipped around by accident:  The rims are 50-622. The old tube fit 44-62mm width. The new tube fit 30-45mm, so no surprise it burst. What do you think, should I replace the rim tape? Any special way to clean the rim? Or should I just use a tube that's big enough and go ride?

Yeah, I didn't realize that 700c and 29" rims were both 622mm according to ETRTO sizing when I bought the tube that burst, so I feel a lot better about looking at big wide 29" tubes rather than trying to find the largest 700c tubes.

Dumb question: I've got a Shimano Nexus 8-speed internally geared hub. I don't really love the revoshift twisty shifter it came with. Could I replace with an 8 speed (for lack of a better term) clicky lever thumb shifter?

I've found it's easy to use a one-size-too-small torx driver and strip out your tool and your bolt, but if you use the right sized driver (namely, the largest one that fits) you can go nuts.

I need one of these: https://hollandbikeshop.com/en-gb/b...m-frames-black/ But I'm in the USA. Any ideas where I can find one and not pay 10-20x the cost of the part in shipping? (I've also left a voicemail with the shop I bought it from, maybe the'll have something).

Maybe. If I had nylon filament. I could probably make it work with PLA+. I whipped something up out of a leftover scrap of Kydex that will probably work fine until I can get the real part or get around to modeling the part.

Kick stands? Center stands are where it's at (for both loading cargo and generally getting in the way). Unrelated: My wife got a peloton and I'd like to be able to use it too sometimes. Unfortunately my left ankle is fused and gigantic and bonks into the crank sometimes. It's just enough to be irritating / mildly painful after a few minutes. Are there any spacers I could get that would move the pedals outboard by about 5-10mm? Alternatively, are there any long spindle LOOK Delta pedals I should be looking for? They use a standard 9/16" thread. Edit: apparently I can just stack a few black oxide washers between the pedal and the crank arm?

I got my bike back from the shop a couple weeks ago, and the sidewall of my back tire is very lightly rubbing against the cafe lock in one spot on every rotation. Is this something I can fix by deflating the tire and kinda massaging out the high spot, or should I tweak the alignment of my rear wheel using the adjusters?

Al2001 posted:Work out if your tyre is actually bulging or your wheel is bent (out of true.) You might be able to do this by just observing it as it spins. Tyres shouldn't bulge, ftr, so if it's that you need to replace it. Either way, if it wasn't doing it before the bike shop had it, ask them about it. https://thumbs.gfycat.com/GenuineBeneficialKoodoo-mobile.mp4 The wheel looks pretty true. It looks like the tread / sidewall on the tire "wobbles around", for lack of a better term. It's a Metropolitan Palmbay C1779 in 28x2.00, for reference.

Alright, the rubbing seems fixed-ish. I aired down and massaged the bead a little bit in the two spots where it's rubbing. On the first try, I got rid of one of the rubbing points. On the second try, I made them both worse. I think the third try is the charm, but we'll see how it sounds when I take the bike for a ride. If it bugs me, I'll switch to a Schwalbe tire.Thanks for your help, everyone!

700x35C. You'll usually find tubes that fit ranges of tire sizes. It'll be expressed like "700 x 28-35".

Pennywise the Frown posted:It snapped off. Yeah, the tire dimensions are saying the same thing in different ways. Let's break it down 35-622 - This is the ISO size of the tire. 35mm wide when inflated, 622mm in diameter at the beat seat. 700X35C - 700 is the size in the French system. 700 is theoretically the outside diameter of the tire in mm. 35 is, again, the width. 28X1 5/8 x 1 3/8 -- 28 inches in diameter, 1 3/8 inches wide, and 1 5/8 inches tall, I guess. Everybody's favorite bicycle nerd Sheldon Brown has a lot to say on the matter. https://sheldonbrown.com/tire-sizing.html The inner tube is stretchy and flexible and will conform to the inside of the tire. It's pretty forgiving as long as the size is approximately correct. But also, don't forget: vikingstrike posted:Yep. As kimbo said though, make sure the valve stem is long enough.

Dumb question about Slime inner tubes: I had a puncture yesterday, and my tube self-sealed and lasted another 30-or-so miles. I don't see any debris when I inspect it. Should I patch the puncture, or am I good to just keep riding?

I dropped my bike in my apartment hallway this morning and snapped the tip off of my Magura HS22 front brake lever. Is the best solution going to be replacing the whole lever assembly, or can I find a replacement lever by itself? If I have to replace the whole assembly, what's a good vendor for it, and what is a good brake bleeding kit?

SimonSays posted:Magura stuff is... Special. My first thought would be to write Magura or check their manuals to see if there are individual repair parts listed. You'll need a Magura-specific bleed kit too. Literally Lewis Hamilton posted:I believe you want part number 4055184014165. Looks like it uses a pin. Thanks, I was worried I wouldn't be able to buy it piecemeal when google results didn't turn up anything promising. I'll see if my LBS can source the part for me, and how much they'll want to swap it out / do the bleeding too.

Literally Lewis Hamilton posted:Why would you need to bleed it? It’s just knocking the pin partway out, removing the broken lever blade, lining up the new one, and knocking the pin back in. I mean, if I can't get just the lever and have to get the whole assembly. (On second thought, you're right. If I have to get the whole assembly, I can just pull the lever off of it and replace it that way. Duh) kimbo305 posted:Do you grab that part of the lever? If not, I'd probably just superglue it back on. OK, good point. I'm pretty sure I put the broken part in one of my panniers. I'll try to find it tonight.

Dumb question: is there a way to keep my saddle from sliding backwards? I've got a Brooks C-17 saddle, and it keeps working its way into its most rearward position, which means my pants rub against the saddle clamp bolt. Should I just tighten it more? Edit: looking at it more closely, am I missing part of the clamp?

My instinct would be to go with the brazed/welded sleeve, but absolutely, steel can be welded as strong or stronger than the original piece. I agree, call a frame builder and see if they'll fix it.
