Good reminder that I need to clean out the tool drawer and donate unused tools to local non-profit community bike shop.

I was less interested in the oval-ness than in the subcompact chainrings fitting on a "standard" Shimano crank.

That part is pretty cool. What wasn't clear to me is if the offset chainring(s?) will affect shifting more than they are admitting right now

definitely gonna have clearance problems on a lot of fat-tire road frames, but should fit a lot of more normal race bikes

still super interesting: https://absoluteblack.cc/oval-road-chainrings-30-46-and-32-48-for-110-4bcd/

It's dependent on both the offset and the ovalization to avoid chain/spider/bolt interference

Praxis has a 48/32 set for 5-bolt 110 that solves the problem by using smaller bolts that thread into the big ring, and machining a lip into the spider tabs for chain clearance

It's a struggle, but you cut out his tongue, and his last words are "atmo atmo Atmo ATMO ATMOOOOOGORIHGGHRSHGGRLMGGMMGMgrrglegurglegrr....."

So basically they took two teeth out on each long side of the ellipse (plus the bolt offset stuff, but still). Clever hack.

Naturally, this bike is partially tarck's fault.

Co-worker has a sw8 MASH/Cinelli fixie that he picked up on craigslist for like $200. He just installed a B17 (replete with cut-out and laces) on a straight with the saddle clip facing forward. Makes a zero-offset Thomson look like those lugged Nitto posts with all the setback.

They're double the cost of the ALX (the other 650b fender you can just walk into a shop and buy), but the coverage looks much more complete, and they weigh 324g less, which is actually pretty substantial. The 46mm size might be limiting, but my new Horizons on i23 rims only measure out to 44mm, so it shouldn't be a problem in real life. I feel like I could get away with running Thunder Butts with my ALX, but with these, it might be a stretch. Overall, I think these look like a winner.

I think I have to order these. Fenders with less coverage need not apply.

If someone on here did it, I'd probably like it. Since it was done by someone I don't know, they're a fucking idiot.

So are we tentatively on board with the new SRAM DUB (step) bottom bracket standard? Pretty cool they got something to work with current BSA threaded frames.

And at least if SRAM is beta testing on their customers, it is less likely to cause death compared to their brakes failing.

28.99mm tho. Come on. Just say 29mm. You know that shit is going to measure 29.40mm knowing their inability to machine pistons to correct tolerances (see all Guide brakes).

Boeing does that so much. Parts drawing will be like 5.9986" +/-.030 fucking engineers man. Oh or They'll call out a radiused edge at .03 radius +/-.030 like ok how about I just not radius it then.

lmao yeah, a lot of engineers never learned how to actually make the parts they've designed, leading to goofy stuff like that. I've seen people in my lab (and the engineering undergrads who interned for us the last year) do stuff like try and press fit things into sheet stock and make parts that are impossible to assemble because the screw holes are inaccessible. They learned pretty quick though (and honestly I've been guilty of it before)

If they had called it 29mm people would moan, if they call it 28.99 people with moan.

In the Pinkbike interview they asked,

"Okay…28.99. You guys had to know that you were going to get a rash of shit for not simply saying “29”. Why, then, 28.99?"

answer,

"Here is the straightforward answer. We wanted to be as transparent as possible. When I started at SRAM over 12 years ago, I was a design engineer for cranks who was a bit OCD on accuracy and details. So now as a product manager, when I was asked what the diameter was I told you the honest answer. 28.99mm is literally what the nominal dimension on our design drawing says and so that is what we shared with everyone. We could just round up and say 29mm to dumb it down, but when asked what the spindle diameter is, we wanted to be honest. There is no marketing twist to it, just actual values we have machined our DUB spindle to. We also saw a few comments about “Do they really machine to those tolerances?” The answer is yes. We expect the DUB BB/Spindle combination to perform at a really high level and part of that comes from having to hold really tight tolerances on our parts."

People who are not machinists or scientists ignore significant figures though, so 29.00 doesn't communicate as effectively as 28.99, and 29 is less precise.

29 is less precise, but we are talking about .01mm. No one talks about headset dimensions or whatever to 2 decimal places. Or if they do, it's to sell those oversize ones for frames out of spec.

"29" isn't dumbing it down. It's simplifying for public consumption.

If the rest of that babble is true and they can machine to that standard the goody for them. That's a big ask.

If someone on here did it, I'd probably like it. Since it was done by someone I don't know, they're a fucking idiot.

If it is marketing, good for them. The specifics may make people more likely to remember it. That or I hope people just call them dub step just to be confusing (now that it doesn't step down any).
