Now gaining more altitude...
Palandöken Pass ( Palandöken Ski Resort ) 2972 m 13.5 km at %7.47
A very tough climb, and after we arrive to Palandöken Ski Resort, it shows why. The last 10 km on sterrato. And we have a pitch of 600 m that averages %18.9! A 6 km part of the climb ( between km 3.3 and 9.3 ) averages %10.2. And to add even more difficulty, the climb already started at almosT 2000m and ends at 2972 m. ( The road is driveable for cars from what I get on google earth )

What to do now?
After reaching the top of the climb, you can have a shallow descent of around 2km at %5 to the junction with asphalt, the original Palandöken Pass ( the 2km road is not technical, with only one hairpin with low gradients ( between %1-4 ), so no worries there ). From then, you can descend back to Erzurum from the conventional asphalted descent.
Here is a very tough stage I have designed, from İkizdere to Erzurum, using the tough side of Ovit ( though we start from 538 m, cutting out lots of the false flat earlier, from km 35,5 or so in this profile:
https://www.climbbybike.com/climb/ovit-climb/17046, then climbing Gölyurt ( another very tough climb, 16.5 km at %6.8 ), long flat road to Erzurum ( albeeit with some small hills ), then climbing Palandöken Pass from the gravel side and descending back to Erzurum from the conventional side. 252 km for 5100+ meters of elevation gain, and in high altitude.

Sadly, I haven't found photos of the gravel parts of the climb, but from what I get on google earth, the road is rideable.
