Pegoretti Geometry Change?

DJKinsella89 · #1 10-20-2018, 10:02 AM

Took a look at the geometry chart that was on the newly updated Pegoretti website (https://dariopegoretti.com/wp-conten...SIZES-2019.pdf) and it looks like there’s been a few changes compared to the geo charts found every where else in the internet, mainly in chainstay length but maybe also in seattube length. All of the older charts indicated that the listed size correlates to the C-T measurement while the new chart makes clear that it’s drawn from the C-C. Not having a pegoretti in front of me to through a tape measure on, can anyone shed some light on this and maybe also when these changes may have been made?

Also head angle.

I doubt anything's changed. The same crew that worked with Dario is making them today.

Only change that I see in my (55 cm) size is 0.5 cm longer in the chainstays. I also wonder whether this new chart is accurate.

Something has changed or one of the geometry charts are incorrect, there’s two charts on the internet for the same bikes for Pete sake.

Can someone clarify where the measurement for the stated size is taken, C-C or C-T?

I’ve owned 2 Marcelos, one 55 and one 56.
The chainstay lengths stated in the “new” chart are longer by 7 mm.

I can confirm the chainstay on my 2018 Marcelo is longer than on my 2011 Marcelo. The longer chainstay’s seemed to have started about a year ago from what I can see. It’s defintely visable in photos when photographed from the side with Bora’s... especially in smaller sizes. This can be seen in a some of the Bike Artisans builds as well as Above Category since around 2017.

Thank you for confirming the change! Do you feel like it makes for a noticeable effect while riding? The chainstays seem long for a race bike but I’m sure Dario considered it properly. Can you clarify where your 2018 Marcelo pulls it’s measured size from (c-c/c-t)? I have a 56cm 2018 Marcelo waiting for me at home for when I get back from deployment and I’m trying to build a proper mental image.

— To detect a difference between the 41.0 and 41.5 chainstay one would need to have ridden both versions, no?
— I have, and honestly can’t tell the difference. I bet most could not.
— Don’t overthink it and just enjoy the bike. It’s been said of Pegoretti that he forgot more about framebuilding than most will ever know.

I’ll check when I get home. I believe it was still center to center if I remember correctly. I haven’t built up he frame yet so I don’t know if there’s a difference in handling. My new frame was a custom measurement as I was fitted and measured by Dario. The chainstay is 41.5 on a 49.8 frame compared to my 2011 49cm which is 40.5. That’s even longer than than an offf the shelf frame at that size.

Just finished unpacking mine. It is a 58 cm and measures per the chart on the new website, center to center.

The 2005 Marcelo came with a Reynolds Ouzo Pro fork with 43mm rake. A couple of years later, Dario changed stock Marcelo forks to 45mm rake. Having ridden a Marcelo with a 43mm fork and another with a 45, I preferred the 43.

I don't know whether there were other geo changes in the 25 years Pegs were available in the US.

I remember reading an interview with Dario where he was asked about a specific angle. His response was something like "Do you think I really know if this is 72.5? I hold the frame in my hand and when it's right, it's done", or something to that effect. I know I have helped no one with this post.
