Frame req? (Aero, dropped SS, high stack, short reach)

[PeterXu]

Would that still be compatible with mechanical derailleurs?

Yes. Traditional mechanical compatible.

Going to be a nice bike for sure but not for me unless I loose some weight. Kudos though on listening to your customers on many of the attributes !

Max rider weight 120kg, if you are really heavier than that, you know what to do

[Dragos]

in terms of geometry if you are going to have a higher stack, shorter reach, and a chainstay > 420 would you please consider having room for 40mm tires? It would be all road / endurance geometry at this point and I think all endurance bikes in 2025 will start having room for 40mm tires.

Sorry, it would still be aero road frameset just taking a bit wider tires.

OK. So here is our goal to do this new frame, same standard as Faxxxx on headtube and bottom bracket testing.
One piece mold and latex molding
High stack, short reach, more aggressive geometry than Factor but less than Pina X
700*35C max tire clearance, UDH, T47 85.5mm bottom bracket, both top and down 52mm headtube
aero seat post but with two types seat clamps for either 7*7 or 7*9 saddle rails
dropped seat stay, aero design
Size 54cm weight would be around 895+/-30g after painted and with front and rear derailleur hanger mounted.
Here is my only question now: which position do you like the battery located ? Seat post or low side of bottom bracket ?

Seatpost if possible.

 LOL Yep !

 Impressive ! I only mentioned it because the Pina has a 85KG weight limit. I am 100 at the moment but usually am 90 or so. Ill be in for one Peter as long as the numbers work out. The R01 is a long for me with a 100mm stem but perfect with a 80. Using that on the trainer right now.

I am not sure you need tires >32mm on an aero road bike as 30-32mm would be your best bet on road. The GP 5000 S TR only go up to 32.

I think a lot of other people were saying they would want a bike with endurance geometry (high stack / short reach) but "aero looking" such as horizontal top tube, deep head tube as there is a big gap in the market at the moment.

 I think 35 should be the max. 30-32 is the norm for the professionals and us mortals could use a bit more cushioning. For some races 35mm tires are being used so there must some merrit to the larger sizes. It has been shown that within the same brand/model of tire the larger sizes are faster when running at the same pressures but give better comfort.

 You mention the 5000 s only going up to 32 but that will change where other brands or race tires can be had in larger sizes. Plus the 5000s is hardly the fastest tire out there now.

Paris-Roubaix was won on 32mm tires this year. Even if your local roads are not fantastic, they will be still better than some nasty cobblestone sections.

Who likes to have a handlebar like this with the frame Peter proposed ?
Drop ca. 100mm and with a rather high flare.
The concept is from Canyon (at least that is where I came across it) but with adjustable width, what I do not like due to the possible risk and instability.

https://www.canyon.com/de-de/fahrradzubehoer/fahrradteile/ersatzteile-verschleiss/canyon-ersatzteile/canyon-pace-aero-drops/10014134.html

But this handlebar is follwowing the same idea as the frame to have something with a different geometry instead of having a lot of offerings with identical geometry,

 LOL I ain't MVP and there were MANY others running 35s. Was an amazing race, he was going like a bat out of hell no one could close the gap. At times he was doing over 50 kph on some of the cobbles SOLO and won by 3 min. Was one of the better Paris-Roubaix races I have watched.

Ur right tho, 32s will be A LOT better than my other road bikes that top out at 25-28mm.

The ideal frame
- aero big fat bladed fork and aero headtube
- relaxed geometry like the bike peter posted. So regular people can run a long stem slammed and maintain aero position.
- round seatpost (aero seatpost saves 0 watts)
- 32c/35c tire clearance is fine
- Pressfit BB cause I like to use the Shimano bb
- ACR headset system would be convenient

+1 for pressfit BB86!
I think T47 is not ideal due to the very narrow tool interface and the potential to damage paint/BB area when fitting.
I would also like to see a steeper seat tube angle in larger sizes (74-75 degrees) and a zero offset seatpost option.

Yeah t47 is overrated. Even guys from parktool said that it's not their favorite bb type. For me pressfit or BSA.

As fro the tires. I think 32c in more then enough, and we all know that if official limit is 32c it can often for 34/35c. There is no need for wide tires on aero bike, also no need for 420mm chainstay. It's not a gravel bike

[hoot]

I didn't see the geometry chart but a decent 75-80mm BB drop would also be nice, given the likelihood for slightly larger tyres, and it's unlikely anyone would race crits on one of these.

 Has press fit come a long way ? I had a couple Super Six Evos in 2012 and 2014 and the BB sucked bad. They were fine new but needed attention after only a couple years. (creaking) Also - T47 has lots of tool interface on a road BB and even on wider a 86mm bb are fine if careful. Just don't use shit tools/BBs. The only drawback is they don't look that nice.
 Now that I think about it I am sure the bb on my C50 and Master are original and they are 20 years old LOL.
