There was a rumour on Reddit last week (here) about Valverde (and Movistar in general) being really unhappy with SRAM, not being supplied with the gears they want which lead to muscle problems for Valverde. No idea how valid any of that is though.
I've heard issues with this, which I mentioned as well. This gearing issue needs to get fixed or the team needs to dump SRAM and just buy what they need or something because they have riders having health issues due to wrong parts.
