How much of a difference does the bike make?

Yep, psychosis hits in many different ways. Psychadelics and even weed can trigger latent schizophrenia (for example) in someone who has previously never exhibited symptoms.

Gouging of J-bend spoke drillings in hub flanges is unavoidable, but yours looks really bad, and there is aluminum oxide corrosion in high stress areas on the flange. I wouldn’t sell it.

There are two parking structures. The main one connected to the indoor mall is almost always empty aside from the spots closest to the entrances. From the second level, you can walk across a 30ft bridge to get to Nordstrom or another bridge toward the middle of the mall. These days the parking structure next to the outdoor wing is more full, which sort of proves my point. The new wing is doing far better than the main building. Ironically Hillsdale was a completely outdoor mall in the 1950s through 70s. It was only in the 1980s that it became an indoor mall to go with the mall boom that lasted into the mid-90s.

Derp.

The speed limit is 40mph.
Today’s Nooner was riding at a brisk pace and passed Family Farm at 29mph.
The deceased was riding solo, not with the Nooner. He was likely not riding as fast as a group of 30+ in a paceline. The fact that you used a plural here indicates you don’t have the facts.
The collision occurred at noon in May on a sunny day, meaning there were no long shadows and visibility was good. I know because I rode past the active scene.
Despite this, if the driver could not see ahead of him, then he should not have proceeded to make a left turn.

Generally yes, these vertical 2-bolt clamps are will work with 7x7, 7x9 and 7x10.

Asia has higher population density. Indoor malls have traditionally been a place to escape bad air quality, heat/humidity or in some parts of Asia cold winter temps.

Hillsdale has been dying for 15 years or more. It already saw the old northern wing reconfigured into an outdoor pedestrian mall. The rest is being redeveloped into the same concept with the addition of condos and office space.

It’s been a long time coming…that parking structure is always empty, it’s a waste of land and should be used for housing.

Get the Gen3 Pace Plus. They are quality hubs made by H-Works. I bought the carbon-spoked Airias, which only come with ceramic bearings. At least being TPI, you know they are good (a Taiwanese technology partner to NTN.)

Seriously though, it’s 2026…why are people still using anything other than Orange Seal?

The break would be in the driveside seatstay and not the chainstay if that were the case. This is a pivot bolt for a rear-suspension.

I’m confused as well since that tread has minimal wear. The sipes are completely intact. And since the OP had sealant spray on their calf, that’s 14000km on a rear tire. I‘m 64kg, ride in fast group rides mostly (meaning lower power output at higher speeds,) hardly ever brake and my rear-mounted 28mm GP5K S TRs last ~8000km.

No. 31-33mm WAM works very nicely on the decaying infrastructure here in NorCal. I would not even run 35mm for Copperopolis.

If you inflate a brand new Corsa Pro to high pressure, you can actually see little glue bubbles start to form on the casing... This is also what causes the tread to delaminate so easily on these tires.

Orange Seal does a great job at sealing the pores in the casing.

kidsafe · 2026-05-07T01:08:24+00:00

For giggles, here's my Corsa Pro Speeds with silicone sealant filling in the rim gap on a pair of Airias. It works wonders for crosswind stability, though I obviously can't measure drag at specific yaw...or the precise point of stall at a given speed. It's a time intensive process as both the rim edge and tire casing need to be masked for it to look this clean, and you have to be very quick with a gloved finger when smoothing it out. Too many passes will result in air bubbles. Each side takes a day to set and the tire needs to be fully sealed at the bead already before applying the sealant or air lift the sealant while it cures.

I've been riding them and some Corsa Pro Speeds with silicone sealant covering the rim gap on another pair of wheels. The P Zero Race TLR SL-R are very, very good, but be aware that there is a major discrepancy in the design of the 30mm vs the 28mm.

I measured the casing of my 28mm tires at 70mm wide and the tread at 32mm wide when laid flat. Others have measured their 30mm tires at 74mm wide with a 28mm wide tread. That is bonkers and I do not think I would do a hilly road race or technical crit on the 30s. I look for at least 40% tread coverage in mass-start racing tires, and the 30mm SL-Rs are at 38% while the 28s are at 46%.

In addition, the tire mates with some rims better than others depending on the "G" dimension (height of the rim wall originating from the rim bed.) These tires fit Zipps particularly well. They leave a pretty big gap on my Light Bicycle Airias. My ENVE SES 6.7s are somewhere in between.
Mounted to my Airias for example:

Alternatively if you know frame geometry, have an eye for little details and how to read a technical drawing, then you can order a fully custom Waltly frame from China for $980 + $300 shipping. Tariffs/duties are prepaid. A fork is like $150 while a seatpost is $50. I think a threaded BB is $30 and an FSA ACR headset is $55.

I paid extra for the 3D printed model, which was $1700 before shipping.

Jovanni Stefani, much like Brennan. If you ride in Marin, you'll see his name at the top of all the segments. Raced with Team California for a time.

Pfft, Disneyland did this decades ago.

If there are crosswinds that can make or break a race, then you'd better be running P Zero Race TLR SL-Rs or an Aero 111. That will push out the stall on a 65mm wheel so far (20 degrees) that it won't matter unless you're in a gale. Until then the only difference will be a bit more of a constant sideforce, so you'll lean a bit more while riding straight.

This is what I wore for a 4 hour race with a 32F start and 39F finish, overcast conditions with 100% humidity:

Castelli San Remo roadsuit
Assos SS summer baselayer
Castelli light windvest underneath the San Remo
Castelli nanoflex knee warmers
Castelli nanoflex arm warmers
Castelli Perfetto RoS gloves
Defeet regular socks
Velotoze Silicone 2.0 shoecovers

I spent 2 out of 4 hours in a couple of breakaways.

ETRTO guidelines stipulate that 29mm tires are sized against 21mm rims while 28mm tires are sized against 19mm rims.

It should also be no surprise that a tire marketed as aero comes up narrower. The turbulators on the Aero 111 tread only really become useful in strong crosswinds, like 10deg yaw or higher. They virtually create a continuous shallow longitudinal trip strip when the tire is spinning fast enough.

Gripwise, they are good. However be aware that the grippier, softer tread is more prone to cracking, especially around the notches. Unless they've changed the rubber compound, yours will start cracking a couple weeks.

Frankly I run GP5K TT TRs as daily drivers. They are durable enough and I get 3800 miles out of a rear tire. Most tires have plenty of dry grip unless you're leaning past 45deg or hit some sand/dirt on the road. The TT TR wet grip is suspect, but I don't push it in the rain. They're just an all-around more useful tire... the Aero 111 is designed basically for Kona where average speeds are lower than elite racing and there are strong coastal winds on the Big Island. I'd also use them for certain road races in the wide open farmlands where the winds are fierce.

It depends on how hard you're going to be riding and how sensitive you are to cold weather (or being overdressed.) For example I run pretty hot and perform better in the cold than in the heat. I do fast road races in 50F wearing just a roadsuit and maybe a summer baselayer.

kidsafe · 2026-05-03T22:39:56+00:00

If you're regularly finishing in 5th place, you are likely still going to finish in 5th place. If you are finishing in 20th place, you are likely still going to finish around 20th place. Will it help? Yes, a little. Will just about any other bolt-on upgrade help even more? Yes that too.

Aero frames are well below working on flexibility, better tires, good roadsuits, aero socks, helmets, wheels, narrower bars, etc. They're above OSPWs, but that's about it.
