Norcal style "aero testing" is a waste of time

Very constructive comment, i guess you didn't pick your username randomly.
Fast on the flat. And nowhere else.

How do people like the Mavic speed release and wheel compatibility?

There should not be any wheel compatibility problems with Mavic Speedrelease as the axle dimensions are equal to normal thru axles. That said I was very close to getting the 168 in stead just to get rid of it.

What a beauty, really gorgeous looking bike.

How was mounting the calipers? Well faced? Also gone er9 on mine, you use the included adapters or did you need to buy a separate set?


Thank you! I used the adapters that came with the er9. 140mm rear. That might be why I don't have clearance issues. However, no space on that frame to tighten/loosen the rear caliper to bracket bolt for er9. Once it's on the frame, I can only access the lower bolt. That was enough for me to get proper alignment.

No rubbing on brakes. I managed to align the calipers without any further actions on the frame.

Using the same wheels, could you do a NorCal kind of video on a loop you know well, swapping 2 or 3 bikes? You have to use the same wheels for any credible kind of comparison. Your times would be interesting, but equally interesting would be your impression.
I take issue with the "because it's 500usd it can never compete with a 1500usd frame", given the 268 is t800&1000, EPS moulded, proven geometry & shape: it's latest best practice afaik. Now yoeleo or the likes are, afaik, just taking oem frames and branding them for a premium, just less of a premium than western brands. Having looked at their specs sheet, manufacturing methods, reputation for QC, the reason why I don't buy them is because I don't see that my money would go into the frame.
I'd like to be proven wrong, because I can afford to pay 1500 for a frame, or 5000 for that matter, but i care about relative value.
Last, i saw you have a colnago video, any chance you would test ride that with your own wheels for comparison?
Colnago Vs velobuild video would break the internet :D

Based on the hundreds of messages I received over the years, the typical viewer of my channel isn't looking for VeloBuild to be an equal alternative to one of the major brands. What they want is assurance their money won't be stolen, and that their collarbones won't be broken from a random catastrophic failure. Basically is the frame good enough all things considered. I try to keep my videos light-hearted and sensible. Save engineering and race opinions for the engineers and racers.

Confirmation bias and cognitive dissonance is human nature. Whether VeloBuild or Specialized, we all want to believe we've made the best purchase. No harm in that.

I've explained how it's bad like 5 times, cba for a 6th so just look at peak torque or dan bigham with ineos

I don't really get worked up by "testing" that norcal does. He doesnt make scientific claims and seems to just be making videos about the testing that he does to try and decide what equipment he is going to run. He even says stuff like "i think i get better traction over crappy roads on wider tires and therefore for my riding ____ is the best for me." Is that theoretically valid argument? No. Grip on an ideal surface is only a function of normal force and CRR, contact patch has nothing to do with it. In the real world is he right? Maybe?

Reality is that this stuff is really complicated and trying to create repeatable results that are distinct enough to make an unqualified claim is hard even with better experimental design and better instrumentation. You hear that from Peak Torque now too in the way he discusses results. Its a change from a few years ago despite his experimental design and instrumentation being among the best of the popular you tubers.

This is a very long winded way of saying that I think experiences are still worth sharing and discussing even if they aren't "scientific" as long as you acknowledge the limitations of your insights.

I think that learning if the price is worth the headache is way more important for these bikes than aero testing or whatever and you do a pretty great job of that

Test rode the bike today. Feels great so far. Only issue that came from the ride is the fork plug seems to have moved a bit. I had headset play during 2nd half of the ride.

 I did install a longer plug  (same design as VB supplied but 50mm) and tighten it down to 9 NM. I am surprised that it moved.

Do you guys also add carbon fiber grip paste? What torque do you put so that it does not move? I would like to know what you guys do to make sure it is secured in the fork.

Some people had similar problems with the 168 (se the post on the 168-thread from september 16, 2023) - but the solution was to add a microspacer (1 mm perhaps) between the frame and lowest spacer (the one that fits the frame and also comes painted as the frame), to get a better compression. I think the problem may be that the spacer touches the frame more than the bearing and elevating it 1 mm from the frame solves that.

so far so good for me. I have the two axles on my 268 and one extra that lives on the trainer for ease. The front comes on and off really easy and quick. The back is also not bad but I find that I need to pull it out a bit after it finished unthreading to get it off but no big deal. Highly recommend getting a spare for the trainer as I personally wouldn't like having to pull the whole thing in and out to mount to a trainer as it takes a bit of push to insert the axle for the first time but easy once it's set.

I had the same problem with the expander that VB provided an a similar but longer one. I then bought the SL7 replica expander and tightened it to 8nm using carbon paste. Now it is fixed, no play at all after 1000km with bad roads and some cobblestones. I would suggest to try this route, because you were able to build it without play at first. Not to mention that a micro spacer with head set play might eat up the fork very fast.

I was reading that if a wheelset that was 12mm and 15mm compatible (by changing the end cap) then the Speed release might be an issue but maybe that is less common of an issue for road wheels.

Why the SL7 clone? What's the functional difference between a SL7 clone (-+25usd) and a cheap, long expander like this one (3usd, 90mm long)
