I've started commuting! Made the trip to work and back about 3 times so far. Getting back into tip top shape is hard!

Anyways, some of these spokes are popping off my rear wheel. Is that bad? I got home one day and found one lying on the ground beside the tire.

Totally normal. Once you lose 36 of them it will stop on its own.

You shouldn’t be riding on a spoke for longer than it takes to get to a bike shop, and you shouldn’t be breaking multiple spokes at all.

Is there a groupset out there that you could run a 28t direct mount chainring up front, a 11-52 cassette in the back, and then brifters with hydros that hook up to a 4-piston brake caliper?

Yeah I have a garage that I used to lock the bike in, but the trainer and stuff is in my apartment since I like to watch TV while biking :kiddo:

I think if I got a nice bike I'd put the RC120 in the garage so it's easy to use for errands and put the nice bike on the trainer

The crank/chainring is irrelevant since you could mount up anything really.

For the brifter with a 4 piston caliper, yes, SRAM has some.

eTap AXS (12 speed) is compatible with the 4 piston Levels and g2 brakes.
Then you’d just pair it with a SRAM MTB RD.

Grabbed a Giant Sedona LX for $40 off Facebook. We'll see what it really needs after a tuneup, but for that price I have a decent amount left for fixing whatever sucks.

Safety question: I've got QR skewers holding in 203mm rotors with 4 piston downhill racing brakes. Technically this is within the manufacturer's spec for the fork, but am I asking for it with this setup? I was going down a 50% gravel grade and this popped into my head. I would love through axles but I'd need a new fork and wheel.

QR dropouts plus disc brakes is an engineering nightmare, but you’ll be all right if you have decent skewers that are tightened properly and checked before your ride.

Bigger rotors are actually slightly less bad here. The axle experiences less of an ejecting force for a given braking force.

That's interesting. I have some DT swiss ratcheting skewers I could use but I find them very mysterious how tight to do them up. QRs are easy enough using the "did it bruise your hand a little" test. I think my QR skewers are nameless ones though.

It’s the cheap, new, external-cam QR skewers that can’t get to hand‐bruising tightness that do people in. Those and the keyed, leverless systems that exist for antitheft purposes. Those should only be used on wheels with rim brakes.

In principle the “lawyer lips” that modern forks have, the ones that make quick removal not actually quick, those are supposed to to prevent catastrophe if the lever is flipped open in transit and you don’t notice. Do they work? Try not to find out.

If that works ok, that makes sense. Other airtag mounts would be easy enough for a bike thief to rip off if they scanned the bike for an airtag because they look generally obvious enough since they have to be able to get their signal out (so nothing inside the frame). That would definitely deter a casual bike thief who knows enough to check for a tracking device because they'd either not be able to find it, or if they knew to check the tire, not want to spend the time or have the tools to do what they need to do to get it out.

You need a fat loving tire with enough air pressure for that though.

We run a 225 mm rotor on the front of a tandem with hydraulic brakes and Quick release front and rear. we are often braking from 40mph+ so I push these thoughts out of my head.

Easy hill, already part of my most common training ride, which is essentially the stinky spoke route. Up tolt pipeline, down to the watershed, through to the PSE trail and back in a big circle. The other end of the tolt pipeline has a much steeper hill. Go to the dead end signs, climb the barrier, and then ride down (don't die) into Blyth park. Its so steep that it has pedestrian switchbacks at the top. I don't know what grade it is, or what any grade is, but so far that's the steepest patch of gravel I've been on.

Once you do it enough times and realize you don't have to be as gentle as you thought you had to, you can do it pretty quick.

We blew a tire on the road for the first time when we took the Fairlights out for their first trip, glass on the path, and it was the one time I didn’t bring my tools and a tube. Ended up riding 9 miles back to the car and driving out to pick my wife and her bike up. Those are tubed and it turns out I’ve probably had similar punctures on the tubeless tires on my other bikes a hundred times that just ended up sealing and not being noticed.

Wondering now if I should just set the Fairlights up for tubeless (they have Hope 20FIVE wheels that are already taped), or if I should just stick with tubed for ease of changes. They’re for touring and I want to keep things as simple as possible but it’s hard to argue with tubeless puncture self sealing.

I hoisted my bike not entirely over a thornbush like an idiot last week, trying to cross a swollen creek.

It has a half dozen places where the sealant did its job.

Tubeless stays winning.

e: “Trying” is misleading because I did get over the creek, it’s just that there was a ford upstream a short ways that I crossed much more easily on the way back. When the creek is low, it’s worse than the thornbush ford, but it turns out that it’s rock-hoppable even with high water.

As someone who did road tubeless years ago, I have a love/hate relationship with tubeless.

I'm assuming that it's less of a pain in the rear end nowadays?

I have been out of the bicycle game for ages so I don't know what's going on anymore and am using this thread to try to dip my feet back in before I rebuild a frame that I've been meaning to build for years.

Looking at my old pedalroom page, oh my god has it been that long?

Not if you seal the spoke holes with tape and use impermeable tires that fit well against the rim.

Car tires haven’t used inner tubes probably within your lifetime. Car‐sized nner tubes are now used only for recreation on the water.

Bicycles generally also require sealant to make them acceptably airtight, because the engineering and manufacturing consistency is kind of bad.

Tubeless tires use a bead on the tire similar to what cars use to "hook" the tire into the rim to provide a seal.

Rims made for tubeless tires either have no spoke holes, or run a liner (similar to standard rim tape, but thicker) to seal the spoke holes to prevent air leakage.

Tubeless tires are harder to take off and put on (due to the bead), but the idea is that if you're running tubeless in conjunction with a liquid sealant to seal any punctures, you won't have to remove the tire other than to clean/replace the sealant or replace the tire entirely.
