9T is a gear ratio for a beast.... :(

[Andrew Park]

I finally received 9-11t cog of doval.

I entrusted the setting to the shop that I frequently visit.

The gap between lockring and chainstay body is originally 3mm....

After 9-11t setting, it was pushed to outside for about 2mm.

I removed 14t, so the composition made like 9-11-12-13-15-17-19-21-24-28.

There is approximately 0.5mm difference between chain and chainstay, 

compare to before mounting and after mounting. (I inserted slightest washer)

And it is right on the cog, so there is no worry about frame that might be hit from shaking chain.

Shifting line was twisted after installation, I did following setting.

I even need to set the tension again.... :)

Finally, I did test riding.

After I have a short riding in my village, I felt it is a gear ratio for a monster.... :(

I thought my maximum speed is about 45km on the flatland.

and estimate that I can push speed up to 50km on 9T with 90 cadence,

 however, the torque increased proportional to.....

So, I reset the setting cause I'm not a monster.

I hope to challenge to 9T again if I increase my engine. :)

I'm much satisfied that I can feel 9T without capreo, and feel the limit of my body.
