OR -- quote:So it could just be a particularly flexy fork Maybe... the blades of the fork are able to shift a bit and steadily drift under use but somehow get reset when you redo the skewer. I think the bearings are much more likely. With cone bearings, redoing the skewer and tightening everything will have the expected behavior of centering the hub around the axle and thus centering the tire in the fork. If that's the reason, a stronger skewer would hold things together for longer, but ultimately you'd want to adjust the cones, if possible, or address the bearings (replacing the whole wheel might be worth it or more possible over having the bearings serviced).

Heliosicle posted:Seems to move over time yeah, although the wheel seems (mostly) true, without side to side wobble when I spin the wheel. A flexy rim won't cause this. Your rotors are attached to a solid chunk of metal (the hub) and not the rims. Either you have incorrect preload on the bearings, play in the bearings, a flexy fork, or aren't doing your QR tight enough. Also you should spin your wheel and let it coast...are your rotors still wobbling? If so, you should true your rotors anyway.

Dumb question - how often do you have to replace tubeless sealant? How do you check to know its time to replace it?

Or take the e.pilot approach and just completely forget to do it until you get a flat because there’s nothing left to seal it lol. That reminds me I need to check my sealant, it’s been *checks notes* like a year

meltie posted:Why are people removing the tyre? Because it’s the only way to fix a non-sealing puncture in a tubeless tyre if you don’t have the 1 type of plug that works for road tubeless. Giant apparently don’t mention plugs when they sell you a tubeless setup bike, and don’t even sell that type of plug. Nor do most bike shops in the UK. I’ve seen inexperienced riders have a bad time, having been sold tubeless as a magical end to punctures - I don’t doubt that it can work and is worth it for some.

I'm getting a lot of conflicting info about tubeless and I don't know whether to believe the people that ride their bikes or someone that has cool anecdotes about a friend they knew once that was sold something maybe.

My cousin in Trinidad won’t get tubeless cuz his friend got it & became impotent. His testicles became swollen. His friend was weeks away from getting married, now the girl called off the wedding. So just pray on it & make sure you’re comfortable with ur decision, not bullied

Helmet chat: So I ended up going to my local bike shop as recommended, lady was super nice. I found one that seems to fit really well... but.. like it's supposed to just kind of sit high up on the head? it comes down to 1 finger width above my eyebrows in the front which is what she said was a proper fit. It just looks kinda goofy. I guess I'm probably just used to motorcycle helmets. It's an Align II XL from Specialized. 60 bucks after tax and its Mips rated if thats even something to consider. Did I do okay? Wendigee fucked around with this message at 00:21 on Oct 14, 2021 |

Sab0921 posted:Dumb question - how often do you have to replace tubeless sealant? I have a KOM Cycling syringe with a thin hose. It goes inside the valve and I can suck out the sealant pooled at the bottom. I can't answer the second bit definitively. Here are some variables that will affect sealant evaporation rates. - Tire construction, air retention. Basically this means the tire is better sealed, period. Something like the Goodyear Eagle F1 tubeless tire loses less than 2psi a week. My current Challenge Strada Pro tubeless tires are losing 15psi after one day, albeit I've only had them installed for a week. When I checked the Orange Seal in those tires 3 months later, it was was if there was no evaporation at all. - Environment. Humid vs arid. Hot vs cold. Bike stored with tires exposed to direct sunlight or not. Again, a huge effect. A bike stored in a cool, dark place won't need its sealant changed often. - How much do you ride...This is a continuation of above. If you ride more, you'll expose your tires to more sun and probably more heat. - How much did you use to begin with. Use more and it'll stay liquid longer. Use less and the rate of evaporation increases because more surface area vs volume. - Sealant brand. Slime basically doesn't dry out. Bontrager sealant also lasts a long time, but also seems to weep through tire sidewalls more readily. Orange Seal is one of the quicker drying sealants, but it's the only one you should use. I would not use Orange Seal Endurance unless I lived in a very hot climate. NorCal summers do not count.

I've got a little skull edge there and it seems to catch on it comfortable which I'm guessing is what your asking so it won't flip off towards the front? Yeah, it should tighten up comfortably snug around the base of your skull. It’s not so much to keep the helmet in place on your head (though it does do that), it’s to support your skull as evenly as possible. If it’s comfortable and moves your scalp around when you grab it and shift it around, you’re good to go.

Have never tried adjusting the bearing but will look at how and give it a go Re: flexy fork, the reason I mention this is that when I undo the QR fully the fork spacing expands by quite a bit (5-10mm maybe?), far far more than the fork on my road bike. The rotor seems to have a little wobble when I spin the wheel, but (due to the dynamo I guess) it only completes a couple of revolutions so it's hard to eye it up. There didn't look to be any contact with the pads though. Seems like my best course of action is to get a better skewer and also check the bearings and see how that affects things

I've never had issues with endurance sealing in winter here, seems to work just as well in any weather I've just pulled the winter bike out of storage and still got plenty of orange spaff sloshing around in there, tires inflated back up no issues at all

Question I should know by now. Is everyone just topping off sealant as needed until the next pair of tires or do you actually remove the tire and clean out dried up sealant gunk at some point?

Hi thread, I have a question. Do you guys think it's safe to ride my Giant Defy 0 2015 on my smart trainer with the seat post clamp having only one bolt in, the upper to be precise? I weigh 73 kg give or take - I believe the clamp takes two bolts because the Defy is tailored towards heavier riders (?). (I added the link as there's a picture of the seat post.)
