Also I'd love to hear a good argument for running tires wider than say... 32mm with tubes

It costs less?

Does it?
For comparable tires it seems like it's between zero and $15 more for the tubeless ones, plus a bit of sealant. Figure two or three tubes per life of tire puts you almost to the same price?


Sure, but like, a rip that bad would've hosed up any tube, too, maybe too bad to patch/boot?

Do the rims cost less? Cheaper speced bikes often come with tube rims and tires. I mean technically with enough tape and sealant anything is tubeless.

I guess tubeless is that good that it's worth carrying all the extra kit?

Add for tubeless
- CO2 inflator in case you need to re-seat the bead
- tire plugs
- spare valve stem
- spare valve core
- spare sealant

Standard kit
- mini pump - still need for tubeless for small pressure modifications
- tire boot - still need for tubeless for large holes
- spare tube - still need for tubeless just in case you have a gigantic hole
- tube patches - still need for tubeless in case your spare tube gets a puncture

Full disclosure I use the ridiculously bougie tubolito tubes as spares. They're expensive af but are super light, pack down way smaller than normal tubes, and I've been able to use them in emergencies then pull them out and re-roll them for future use once I get home.

Those look pretty interesting, but a lot of the reviews I'm reading seem to indicate they have a lot of quality control issues.

WTB don't hold air? I was really looking at the Resolute. The Schwalbe G-One All-round that I have are terrible at sand and loose dirt. My front slides out on corners and rear spins on steep climbs.

How is Gravelking SK in those conditions?

SKs are real bad at washing out. Give the GK EXT a look, it’s the same casing with a more aggressive tread.

Dang only goes to 38mm though. Do they run big? The ones I have now are 40mm and I have about 10mm clearance on all sides. Trying to go large.

Is Gorilla tape legitimately as good/better than special tubeless rim tape? Or is it one of those "just pay for the special tape." It's not the price - I have a bunch of Gorilla tape lying around already and I don't want to wait for special tape. But the Gorilla tape has really thick adhesive, is that not going to be a mess?

It’s a mess to clean up when you want to inevitably lay down new tape.

Just get some powder coating masking tape, it’s the same thing as tubeless tape for a fraction of the price.

being able to lock up brakes says nothing of required lever force and modulation, if that’s your criteria of good brakes then rim brakes are just fine too

They don't lack stopping power is what I'm saying. And yes I am saying my hands get tired from modulating the lever with force for long durations.

How does the Hy/Rd compare to a full hydraulic setup?

Well my mechanical disks are very adequate for the road, but I'm taking my gravel bike down single tracks and stuff where I should really be on a mountain bike, and there have been times where I thought my hands were going to fail.

I'm running Tiagra which is fine, and the full Tiagra hydro levers, lines, calipers is about $240 on eBay vs the Hy/Rd at about $100 less. Hy/Rd is almost zero effort to install, whereas the full setup will allow me to be sequestered to the garage for a couple hours. Tough choice.

I just put on my first set of Continental GP5000 tubeless, now drinking beer to ease the pain in my thumbs.

Those are some massive thumbs if you did without levers.

I put on a set with tubes to set in the tubeless rim tape. The next day after I removed the tubes, the tires had stretched and basically fell back into place with very little effort. It's hilarious how much of a difference it was.

If I have two wheelsets with two different cassettes, do I have to change my rear derailleur indexing when swapping? It doesn't seem like I would, but you never know. I want to go to 11-36 or bigger for offroad, but keep my on road 11-34.

Alternative take, if your wheelsets have different hubs, you may have to. I have two wheelsets with the same exact cassettes, but different hubs. I give one good half-turn when I switch between them.

One of my hubs is 11 speed with an adapter ring for the 10-speed cassette. I have identical 11-34 cassettes and everything shifts perfect with no adjustment.


e.pilot posted:

This, also I go between a 9-34 and 10-42 without adjusting the b-screw no problem.

Now I'm actually thinking about going up to a 40 or 42, but that would need a Wolftooth Roadlink or similar. There should be no issues still using the 34 with the Roadlink on there, correct?

FogHelmut
Dec 18, 2003

So I got a 11-42 and threw it on to see what would happen. Longer B screw wouldn't do it, so I had also ordered a Wolftooth Roadlink. It works perfectly, only needed a small barrel adjustment. Only issue is if I do big rear to big front, my chain is a little tight, but I don't anticipate needing to do that ever.

With my other wheel with the 11-34, I basically have to pull the B screw all the way out for it to be within range, but it still works with the Wolftooth attached.

Picked up a used Fuji Newest 2.0 for a good enough price for my wife to use. Its got some weathering but is otherwise straight and everything works.

My plan:
- Toss the Sora components, they have significant mileage and wear.
- Buy myself GRX components for my bike.
- Move my great condition Tiagra gear to the Fuji. Crank, derailleurs, brifters (I had previously upgraded mine to hydro brakes so I have the other set of mechanical brifters sitting there. The rim brakes are going to be fine for her use.)
- The 10 speed cassette SHOULD fit on the 9 speed wheel, correct? With a 10 speed chain.
- Is there any reason why I would need a different bottom bracket with the crank swap?
- The wheels are 622x14. The frame looks like I can max out at 32mm tires. They SHOULD fit on those rims.

I guess this is a good place to ask as well as the AI thread.

My new wheels mention needing minimum separation from car exhaust. My hitch rack isn’t far enough out currently. I’m thinking of adding a riser to get the bike up higher and away. Any other ideas?

Complicated heat shield on the rack, or move your exhaust.

Literally Lewis Hamilton posted:

It's a dual exhaust, and it's a 1up hitch rack, so there isn't a way to take off one or two wheels.


Wondering if replacing the tips with a down facing tip would work?

I mean, I'm assuming the issue is direct application of hot gasses to the wheel. Radiant heat from the exhaust pipe itself shouldn't be an issue unless you're very close, or driving extremely aggressively for extended periods.



quote:

“Rear-facing exhaust tips that line up with the bike rack and lower portion of the rim can do the damage,” said David Agaptio, tech services and warranty manager at DT-Swiss USA. Fogle suggests adding turn-down tips to redirect heat away from your rack and bike. Another solution is to add a riser or swing-away kit that safely spaces the rack away from the exhaust.

The sticker says a minimum clearance of 45cm/18' behind, and 20cm/8" above. That is a pretty sizeable length for a rack to be away from the car.

Yeah I'm not sure how that's possible with a hitch carrier on most cars.

I might have screwed up my cable length, and my front brake line has been rubbing against the head tube on my frame when I turn right and there's some light scratches. I stuck some clear 3M vinyl on there because I don't want to fix it. Anyway just here to confess, see ya.

Made a water bottle holder for my kids bike that doesn't have mounts. I had some velcro straps and bought a $5 cage. I put an old inner tube piece around the bottom of the cage for grip and to protect the bike paint. I spread some silicone on the back of the velcro straps for more grip. Then I riveted the straps to the cage. This holds pretty tight.

Any recommendations for a maintenance stand for occasional home use? Or a good inexpensive way to hold up a bike (like something I can mount directly to a wall?). The Park Tool stands are all too fancy and professional and expensive for the little use they'd see, but I don't want to buy some $50 piece of crap on Amazon that's going to fall apart in 20 minutes. There's got to be some kind of in-between.

I've had this Amazon one for a year and have hit things it was holding with a 5 lb hammer and it's still super solid.

I bought a new KMC X10SL chain to fit my big to big gears since I put on a 46-30 front and 11-42 rear. Chain calculator math says I need 113 links. I just stuck it on with all 116 and it seems to work fine and isn't hanging loose on small-small.

Is it true that you can't put these type of chains back together if you remove links? I don't want to drop down a few links and be stuck with a too-short chain.

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.

FogHelmut

Yeah plastic is a better idea.


vikingstrike posted:

Centering rotors can be a pain, honestly. Just be patient and take your time. You'll eventually get it.

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