I want this as my first gravel bike for mixed riding: paved roads, light gravel, and commuting.
Do you think €600 + €100 shipping is a fair deal for this spec and condition?
Is there anything I should watch out for specifically with the 2021 Topstone 2?

Thanks a lot for any feedback — after this I’ll finally be joining the gravel world
