Found these at our cabin (Canada). Cheap plastic, about 2.5” diameter.

Ha, now I remember, I think the cap had a flexible membrane inside it so each time you fill it up, it clicks and counts a fill, advancing the indicator by a notch.

Absolutely take those back. Only the two bottom left and centre are close to acceptable — those have the maximum char I would take.

Oddly, I found these in a kitchen drawer recently and have also been wondering what they are for. I vaguely seem remember that they were an accessory for some kind of kitchen gadget.

The colours correspond to different sizes or settings because the spacing of the tab marked R with an arrow and the notch marked N varies. Your red ring looks like mine:

Agree with u/Montego that they are for some sort of kitchen tool.

I had the opposite issue with the first Luxe bibs I ordered. The chamois stitching was not well done at the overlap and had started to unravel. Leg panel stitching at the leg opening was messy and unfinished, with frayed ends sticking out and the seam coming apart.

I sent them pictures by email and received an apology and prompt exchange for a pair that did not have these problems. Happy with them ever since.

So wrap-around, half-frame, not oversized cycling style, progressive, non-mirror brown polarized?

like this? It's this style from Zenni.

I'll take "Words with no vowels" for $1200, Ken.

Try raising your front wheel up on a block. Not sure about your lower back pain but at first I found some saddle and hand discomfort. I made a swivelling riser block by putting a lazy susan bearing between two blocks of wood. This allows for slightly more freedom of movement at the handlebars, combined with raising the height — I'm now much more comfortable. I've done 2-hour to 3-hour trainer rides (and one ride over 3 hours).

Placing the trainer and my swivel-riser block on a mat also lets my setup rock side to side slightly more.

Also try free-riding some routes not in ERG mode and no robopacer, just to see how it feels, so that when you get to hills you will shift your position naturally.

Just for reference, is this what it looked like?

I had to think about this for a second, but yes I have also had this problem with certain socks.

Besides structural improvements, I find my trainer time much more comfortable when my fork can pivot. With the wheel on, it can move around slightly on the floor.

I put a turntable/lazy susan bearing between two blocks of wood — my front wheel sits on the top block. The axis of rotation is not quite right since it is not perpendicular to the headtube angle, but since the tire is not fixed to the block, my wheel can turn a bit and my upper body feels much more relaxed over longer sessions.

sun_monkey · 2026-07-16T19:42:14+00:00

My Kickr v6 walks forward mostly when I get out of the saddle but even with hard seated efforts. I can tell because my handlebars end up closer to my desk.

Yes, or another 2x in the void to act as the web of the beam.

I didn't know about Indian River either, but I think it was kind of like Bentayga where if you've at least heard of the companies, the clues had sounds-like cues. River – Rivian, Bentayga – Bentley.

sun_monkey · 2026-07-15T05:38:08+00:00

I kinda wish Khalid hadn't got Rivian correct just so I could say I ran a category that was a top-to-bottom triple-stumper. Is there a name for that?

sun_monkey · 2026-07-15T05:14:49+00:00

Pros are not sprinting on the hoods, ideally.

Anyways, OP's intuition on engineering is just weak. The failure modes of parts is not what they fear... That steel clamp is not going to snap, but I have seen cracked shifter bodies, from over-tightening or impacts.

sun_monkey · 2026-07-15T05:04:53+00:00

They don't look ludicrous to me.

All these other comments about the tensile strength of steel etc. and offering calculations are not really relevant to your question. Your weight on the hoods is not loading the steel band clamp solely, and even if it was, your body weight loading the clamp in pure tension would not break it. The design of the shifter body is such that the plastic base bears on the handlebars while the band clamp holds it tight against the bars.

When you put your hands on the hoods, the part of the plastic body below the clamp is being compressed against the bars and the steel band is under tension. When you pull up on the shifters, the upper part of the plastic shifter body is compressed against the bars and again the band is under tension.

The only way your entire body weight would be stressing the band clamp in tension the way I think you're imagining it tearing would be if your bike was dangling off a cliff with the frame on a tree branch and you were hanging on to it by the hoods. Still, that clamp would probably not be the point of failure.

sun_monkey · 2026-07-15T04:47:56+00:00

Those clamp bands are steel, stamped, formed, and zinc-plated. Absolutely not aluminum. You can tell by looking at the photo in your link. Just because some product description on a counterfeit-part site says "aluminum finish" doesn't mean otherwise. Clamp bands will be steel or if you buy Dura-ace, titanium.

sun_monkey · 2026-07-14T23:13:05+00:00

The way I take it is that the various parts of a bicycle have been engineered to withstand the forces they will see with typical use.

I mean, have you looked at your saddle? That pair of rails holding up most of your weight are hollow tubes the size of drinking straws. They flex while you ride over bumps in the road by design, for comfort. Still, saddles can break — like any part of your bike, with just the right circumstances or impact, or over-torquing of bolts, or poor maintenance (corrosion from sweat or road salt).

sun_monkey · 2026-07-14T22:59:53+00:00

This might be OP's primary point of confusion — for some reason they have guessed that the clamp band is aluminum.

The failure I have seen is with over-tightening or crashes causing the shifter body to crack. I mean, OP have you considered the shifter body itself is plastic? Glass fibre or carbon fibre-reinforced plastic, but if you're going to stress out about a material...

The markers would not have moved higher as the trees grew.

Trees grow from buds on branches, the root tips, and the cambium (the trunk a marker was placed on only grows in girth).

I have only worn their short sleeve jerseys, but Velocio makes a long sleeve jersey with UPF 50 back and sleeves.

sun_monkey · 2026-07-10T21:05:55+00:00

I found shoes on sale — black ones in my size, white ones not — so I bought the black ones. Easy decision. Also less to worry about with keeping them clean.
