Tiagra, Sora, and Claris are discontinued
I thought CUES (10-speed) would replace all entry-level groupsets,
but they released Tiagra upgraded from the existing 10-speed to 11-speed.
After more than 10 years without any significant upgrades, seeing them finally release it as 11-speed,
it appears they judged that many consumers feeling price pressure from the 12-speed 105 and 105 di2 resulted in decreased overall sales.
It looks like Tiagra will now take the road value groupset title that the past 11-speed mechanical 105 held.
