Gearing for Ventoux

[T4tomo]

No camping gear just me on the bike. Incidentally I should have added am going up from Malaucene not Bedoin.

Same difference - its a similar-ish profile. Enjoy!

Chain length is not an issue. As we are talking Campag it’s not cheap so nothing is pennies! £276 for the crankset.

Thanks.

Do you have a smart turbo and an app like Zwift that has Ventoux, such as Zwift's Ven Top?

Given the odd virtual climb I've done of this monster, I suspect it's going to take you approx 2+ hours at endurance pace.

Any local hills of similar ~8% gradient you can climb and descend for 2+ hours and see how you do with current gearing?

I can't be certain, but I think this Ven Top ride was 100% trainer difficulty with 34/50 rings and 11-34 when I was approx 78-80Kg back in Xmas '20, so ~2.5W/Kg and a z2 endurance effort.

Yes to all the above and plan to do just that, don’t mind 2+ hours.

So anyone can get up it, on any bike, if determined ...

Anyone in good health, maybe. It certainly would not be possible for many unfortunate people no matter how determined they were!

Indeed. (although I thought that went without saying in the context of this thread! )

My take having done a lot of high mountains on Campag with both 34x29 & 34x32 is that you’d barely notice the difference.
34x34 should be perfectly adequate, and you’ll probably only be looking for easier at the 15%+ mark.

Have you considered just fitting a 32 inner in place of the 34?
I'm sure it is outside of the recommended teeth difference, but in my experience when I swapped a 39 on a 53/39 for a 36, it behaves perfectly - that is DA 9100 in case that makes any difference.

How much is an entire chainset?
The inner ring on it's own is probably relative pennies - my genuine DA inner was £36 iirc.
Arguably, for speed and simplicity, it would be easier to just swap out the entire crankset, although you'd need to swap pedals as well I suppose.

Do you know yet whether you can have a suitable chain length that would accommodate both setups, and or will you also have to tinker with the FD height, relative to the largest cog I wonder?

It sounds like the OP has a 110 BCD chainset, I thought the smallest inner chainring available for this was 33 teeth?
Can you get a 32 teeth for this set up?
