If it is a part that they literally cannot get, there is no harm in asking.

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.

Not saying it's not the tyre, but I've never seen a tyre behave like this (others might have), and my bet would still be that the rim is slightly out of true, or maybe even the hub is a little loose (this would make the whole wheel feel loose if you lift it off the ground.) If you want to check the rim is true, you could tie a zip-tie or similar around one of the stays, level with the rim, postioning the end of the zip tie 2mm from the rim, then you can observe lateral movement of the rim in relation to the end of the zip-tie.

You're probably better off just taking it back to the shop though.

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!

Do you mean the WAVE ADJUST or whatever? I've played with that for hours and never seem to be able to get that screw to do anything. If there's something I'm missing I would really like to know about it!

I've tried bleeding the brakes from both ends with the screw fully in and fully out and nothing seems to be different.

I have Saints so I grabbed a pick for those. I guess Shimano calls it Free Stroke adjust.



It just pushes the screw into the fluid and displaced a little bit of fluid, which causes the brake pads to move. If you bleed them with the screw out, you will put a tiny bit more fluid into the system, then you screw the screw in and it should push the pads out just a bit which will cause them to grab sooner in the stroke. It isn't night and day but its noticeable on my Saints at least.

I'll give this another shot when I bleed my brakes before the season starts. Still no announcement from Whistler and I fear it'll be closed all year.

I pushed them to give me a lead time on XT and they said about 3 weeks.

Or August.

Their system claims 3 weeks, but they said they see these ETAs change constantly. I believe it, I've seen it in other industries... supply chains are turbo hosed right now, I just didn't expect to see something like bike parts backordered like this.

At this point consider any ETA a wild estimate. Realistically you should just pretend those XTs aren't coming, act accordingly, and if they do actually show up then reconsider.

Yes I know this means maybe buying two sets of brakes but I've seen a lot of people get completely screwed over by taking these estimates as anything resembling a guarantee.

Yeah I know, I'm trying to avoid being that guy who brings in parts, so I was hoping this 3 week thing was somewhat grounded in reality so I could give them the sale after all this back-and-forth, even if it took more like 4-6 weeks.

All that said, how hard is a hydraulic disc brake install? About the only thing I'm not comfortable with is dealing with actual fluid fill/bleed portion of it. I'm sure I could do it if I had time to sit and fiddle with it, but that is one of the things I'm lacking these days.

I've installed two sets of XT brakes on bikes in the last year. One came with the lever and caliper not yet connected, and the other was fully assembled already. In both cases, they were pre-bled, but I had to cut the hose and connect the brake levers. It was not particularly challenging, and in both cases I managed to avoid losing enough fluid to need a bleed afterwards. YMMV of course, but I'd suggest just getting the brakes however you can get them. Try the install, and if you need someone to bleed them for you afterwards if you don't want to / feel comfortable doing it yourself, then go ahead.

If it comes as a sealed system and you don't have internal routing, there isn't much harm in trying.

Just don't do anything like disconnect the hoses if you don't know what you're doing.

Also don't unbolt your caliper halves to get the pads out. Somebody did this on my shop floor when I had my back turned for 5 minutes.

FogHelmut

Hydraulic brakes are much easier than messing with cable tensions and barrel adjusters. Bleeding is dead simple especially if you have a kit.

When installing, don't pull your brake lever before everything is connected. You'll shoot the plug out of the pre-filled brake hose.

Also don't squeeze the lever without the wheel and rotor installed unless you have one of those spacers stuck in the caliper. The calipers don't return to full open, you'll have to gently pry them apart with a screwdriver or something to get the rotor back in.

Loosen the caliper bolts, squeeze the brake lever to clamp the brakes on the rotor, tighten caliper bolts, release the brake lever?

I ordered some that showed having a handle like a folding knife, so there was something I could hold with my dirty fingers instead of touching the shim and contaminating my pads, but what showed up was just the shim. So no better utility than the biz card. Maybe a bit easier to slip in cuz the shim is thinner.

I thread. I got my bike ready for the year but when I was pulling the pump nozzle off I broke the top part of my Presta valve. It's still holding the air but I'm not sure if I'll be able to put anymore back into it. I'm looking for a new tube and uh, this is confusing. I don't know anything about this.

What's labeled on my tire is:

35-622 (700X35C-28X1 5/8 x 1 3/8) K1083A-002 (tire model I think)

I searched for that and got a bunch of different combinations of those numbers but no tube listings with all of those exact numbers. Which set of numbers should I be most concerned with?

Safety Dance

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

Some tubes come with a removeable valve core that you can replace, but also its a good idea to keep spare tubes around.

It's not uncommon for the tops of presta valves to get a little bent. Sounds like yours didn't snap off? It's not a huge deal if it's working, but you can usually bend them back carefully with some pliers.

There's some chance you have a deep rim, in which case very short valve stems wouldn't poke out enough for you to pump. You can just eyeball your rim against the advertised height of the stem.

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:

A customer came in with a 36 spoke wheel with a drum brake. It was some weird rear end size I've never seen in my life. I think it might have been one of those 24s but the markings on the rim were p feint.

Idk, the old dudes trying to maintain their 60 year old three speed are usually okay with spending $25 for a tire and are thankful when you're the only shop in town with one in stock.

If I spontaneously lose the ability to shift to cogs with more teeth halfway through a ride and it went from works perfectly -> you have 2 gears (hardest two), it’s probably a cable issue right? To be clear I have my 11 tooth cog and the one above that to shift between, and have no problems moving between the two, but the lever is completely stuck and will not go past that point. Happened mid hill. Applying too much force to pedals when trying to shift?

Shimano groupset, grx 800 series mech levers if it matters.
