Great bike. Fragile tyres. Could use steeper rake.

Like the other reviewer, I actually had my first puncture in my first week! And it was caused by the tiniest of thorns! I pulled out a minuscule plant thorn that had gone through both tire and inner tube. The studs for mounting rear rack are M5, maybe M6 would have been a little sturdier? I like the bike, but wish the rake was a bit steeper!

Shifters and gears

I bought this bike for my son, it was more or less configured out of the box. But after the first trips, my son began to complain about spontaneous gear changes. I tried it myself and made sure of it. The cheapest MicroShift system spoils the impression of the bike. I will have to change it.

Clean, sturdy ride.

This bike is gorgeous. Looks gorgeous and rides like a dream. Built like a tank. I'm not basing this review on how many punctures I get, which so far is one. Or just on one part of the bike such as the tyres, but the bike as a whole. If I were to get another puncture though I would blame the cleanliness and condition of the ride surface and/or myself, not the bike. You should not review a bike on how many punctures you get, because that is generally the riders fault for not paying attention to the surroundings when riding. Great bike, you will not be disappointed!
