Nimble and fun urban bike

"I’m happy to see this bike is available again for others to enjoy. Very nimble and fun urban bike that has been taking a city licking for 6 months without being worse for wear. I truly appreciate the light weight for carrying up my building’s stairs as well."

Mykolas (5/5)

Great bike for around town.

"Great bike for around town. Much more comfortable to ride than my last aluminum frame bike. The frame geometry works well for me. At 5'11" and 29" inseam the stand over height gets me onto a medium frame with no issues. Couldn't be happier."

John S. (5/5)

My score: 4/5 Good point:

"My score: 4/5 Good point: Cool blue color. Many peg holes to install the rack and so on. Negative point: Need to adjust the brake in my case (rubbing)"

Q&A

What is the max tire width that can be fit on 700c bike? Are the wheels able to be set up tubeless?
I put 40mm Schwalbe Marathon Winter Plus Steel Studded Tires on this past winter and would say there was some more room, with margins. I *think* the wheels could be set up tubeless with good rim tape, but I only do that on my trail bike.
I see someone stated they were 5'11 and the medium fit them. The size chart makes it seem as if a 5'11 person may not even fit correctly on a Large. Can anyone speak on this? The M is $200 cheaper and I am 5'11.
I am 5'-8", the medium size fits me very well.
What is actually the stand over height for the medium? Is it 758mm or 770? It shows 2 different sizes.
758
What is the weight of the bike, medium size?
I weighed it only after a carbon handlebar, carbon seatpost , and two carbon bottle cages were installed . The total weight of the bike is 24lb 11oz.
