发帖数: 1995 | 1 It is not as hard as I imagined.
I decided to begin from 19T cog first, it gave me an easy start.
Also, I rode with it several times on my errands.
The other reason may be I did not coast much in my road bike because I kept
checking my cadencce when I rode road bike.
I am glad I finished it today, 24 miles total, 9 miles in the morning, 15
miles at night. |
