Anyone have anything they'd like to rant about?

Couple years ago was trying unsuccessfully to seal my tubeless tires so had to pay a shop to do it. Just seeing now they used non serviceable valves on them. That can't be the norm, correct?!

It's certainly not the norm. Thinking about it, I'm not sure I've ever actually seen a non-removable core on a tubeless valve. You sure there's not a tube in there?

Split tube, maybe, like back in the days of ghetto tubeless on non-tubeless rims?

I'm pretty sure i have seen stems with non-removable cores

edit : I found some stems with non-removable cores in the shed, I think they came on a bike with a set of 819 rims almost 20 yrs ago

100% sure.

I wonder if they taped over a section of tube to get a seal on a damaged rim. I just tried to find a non removable core on stem and I can’t find them on the web. But I’m old and all that.

[XXX-er]

most of the stem is NOT threaded on the stems I have with non-removable cores and those came on a 2004

You mean TUBELESS stems?

FWIW, Santa Cruz Reserve stems do not have a core to remove.

819’s were true UST rims in a time where there weren’t a ton of UST tire choices. Removable valve cores were not important with this tubeless system as it did not require sealant.

I just assumed we were still talking about tubeless stems but yeah it was a 2004 Cannondale with 819 rims, delivered with no tubes, it came with maxxis tires they held air and i don't remember any sealant but I did eventualy run sealant when i went to Nevegals which were fast and pourous

The trend to steep seat tube angles is stupid. Or at least the way people talk about it is stupid.

1. The measurement process is sloppy at best. “Effective seat tube” is always deeply appropriate. We could measure or report 75 degrees at 78cm saddle height. 74.5 degrees at 80cm saddle height… also it’s not about where the clamp of the seatpost lives it’s about where you sit on the bike. It would be easy to actually measure “cm from bottom bracket back to sit bone contact point on paddle”… but we don’t do that.

2. People don’t understand their bike fit… saddles can make a 2-3 cm difference in how a rider sits on a bike. Compare something like a specialized Power to a WTB saddle and the specialized will give you 2-3 degrees steeper effective seat tube angle. Old bike + new saddle = steep seat tube.

3. Steeper isn’t always better. It’s better for steep climbs. Worse for pedaling on flats. Worse for pedaling down.

4. People just put their saddles at arbitrary places on the rails… somewhere these is someone riding a bike that they swear climbs much better than their old one because it’s got a steep seat tube angle… and they’ve got their saddle rammed back all the way on the rails.

5. Femurs are different lengths for different riders. This makes a massive difference in how people pedal and move on a bike. There isn’t a one size fits all.

Bike fit has just been reduced to Bro Science and it’s annoying. That being said, I’m glad we’re not riding 73 degree seat tubes anymore.

Shimano's tubeless valves don't have a removable core.

[rideit]

As long as we are waxing historical, I remember that some of the mavic valves didn’t have threads on the shaft, which made some pumps not work very well.

[Roxtar]

A few years a go, I stumbled on my old set of the original tubeless stems, hand cut from a tube by some guy named Stan.
Yes, they had removable cores.

I commute to the city most days. There is a new phenomenon on snow days post COVID. It’s the I’m going in the middle lane at 25 mph person. When the semis on the right are passing you, you need to move over. In a white out like his morning, it just isn’t safe.

Let me guess, driving a Prius/Leaf/Hyundai?

the irony is that I’m the guy in the Prius flipping them off for making him slow down

WTF is this schizz. New fancy Sram Code brakes mounted to a Sram fork with Sram rotors, no adaptors, totally off. They had no power and sung like a cat any time I used them. Waste of money, and even worse I have to bleed the new ones to replace these.

Finishing up a ride the other night in a City open space park I come around a corner and come face to face with a Honda 110 or 150 sized dirt bike on the trail. Guy just goes off trail around me and continues on.

Get back to the trailhead 15 min later and there's a car parked right there in the lot with an empty moto rack on it.

Takes some balls or lack of brain cells to stage right from the trailhead parking lot.

Something about your bedding in process, installation, etc is off for sure.

Extra washer / spacer on your mounting bracket?

Looks about 10mm off. Any chance that's a 160 rotor with 180 mounting?

Did you have a schraeder core tool, by any chance?

[toast2266]

That's my guess. Conical washers under the caliper?

[XXX-er]

no adaptors, totally off.

IME brakes always seem to be mounted with some washers/adapters, I think its designed this way so you can space the caliper out as needed cuz you can't space it in
