That's a long winded way of saying "I put too much pressure in 25mm tires" :P

100psi on 25s is a bad idea. I have actually gone for a descent KOM on 100psi (which I NEVER ride) and ran through a turn (which also happened to have loose gravel). Let some air out (more around 85 psi as I normally ride) and did it again. For the KOM.

Honestly, I think you are grossly overstating the impact of a couple mm. I used to do sportbike track days and wouldn't say the difference of an inch width on my rear tire had the effect you're describing. It did, however, impact the handling (slowing down turning) which is what I feel riding a tire wider than 25. That's it. A couple mm of contact patch is probably not going to be the difference between staying upright or going down in the situation you're describing. I'm not an all trying to convince you to ride 25s instead of wider, I just think "safety" is a bit of a stretch when comparing pros and cons of road tire widths.

And don't bring Gilbert into this! He's a god... But he picked a bad line.
I predict that as much as we like bigger tires now, in the near future we will like them bigger still. We all know that sketchy feeling when we hit some gravel in a corner. We suddenly figure out a way to reduce our weight by about 50%, and become religious at the same time. The first time I hit gravel in a corner on 30mm at 65 psi, I still felt hooked up to the road and finished my carve. Slower handling? Well that's a geometry thing. I've got no bias here. I ride more on 25mm (my Colnago) then I do on 28mm (Parlee) or 30mm (winter bike). But when I go to the mountains it will be 30mm on my secret weapon col slayer.

As for Gilbert, he should know by now, you don't dive for the apex until you can see the exit, or happen to know where it is. :smartass:

Bike is still great, even with 25mm. Ride the crap out of it.

You were replying to a comment about intense, technical descents and you give an example of a descent with 4 corners in 5 miles? That isn't very relevent... FWIW when I was running 31mm actual tires, I ripped descents at 60/65 PSI.
No, I was talking about a time I ran 100 psi and ran through a turn. I linked to the segment where that happened. Some of us ride enough to have experiences to share about more than one road. I'm not trying to pick a a random segment just to try to impress a troll or two on the internet with how many turns are on roads around me.

Hey, this is a safety issue. It doesn't have to be the Lacets de Montvernier. You could get into trouble turning out your driveway if there happened to be some gravel there that you weren't expecting. LOL my driveway has a legit switchback in it :P

And Imaking20, although we have drifted seriously off topic here, I can't resist pointing out that the remarkable safety improvement you noticed between 100 psi and 85psi, is probably less then the difference between your 85 psi and the 65 psi on big rubber that I am proposing.

The bottom bracket arrived today and I was able to get the bike thrown together after finishing up the work day. Fortunately, about an hour (of annoying Ryan) later, there was a break in the rain and I was able to walk over to the park to grab a few photos. Less fortunately, when I got to the park I realized the battery in my DSLR was dead. D'oh! So hoofed it back to the house to grab the Powershot. Not the best depth (because I haven't yet taken the time to learn the settings on this little guy) but I think the scenery helps to offset where I'm lacking!

And the moment probably none of you have been waiting for!!!..... the build sheet...

The weight goal was to end up under 5.8kg so I'm pretty stoked to hit that.
This one will be missed

J&L bottom bracket. Still waiting for a THM
How do you like it? I bought one of these, but rubber shields and extra spacers seemed a bit off-putting, in the I installed Zipp BB back because J&L uses non-BSA30 wrench, which I do not own.
