KendaK191 Koncept 650x23 Black Steel

bought it for my son's Trek 1000. exact match of the worn out tires on the bike before.

650c tires are getting tougher to find as few new bikes come with them anymore. My friend needed a new rear tire for our bike and this worked perfectly. She has about 500 miles on the tire and it is wearing well and should get many more miles out this tire. It has held up well on commutes and training rides with no flats so far.

The tires are not as hard to mount as everyone seems to be saying. Just need the right tools and it'll stretch onto the wheel. Just took a few minutes to get them on, although it does take some effort. The second time I did it was really fast. They can be manhandled. High quality tires from what I can tell so far. Haven't used them on the road much yet.

had a very difficult time getting these wheels on the rim. Used my tire mounting tools to get the last part on when I should have been able to roll it on by hand. Ended up getting a pinch flat. Next go round I put the tire in hot water to loosen it up and while it was better, it was still a fight. Hoping this tire will stretch over time so when I get another flat, it won't be a fight to mount it.

I got this tire mostly because it was inexpensive and had the black sidewalls versus the ugly tan ones I had on previous tires. After over 400 miles in about a year, it still has plenty of tread left. it is not as light as some tires and claim only a 100psi max, but I usually try to keep it around 110. I should mention that I use this tire as a front tire on a 3 wheel handcycle, with 20 inch tires on the rear.

The tires are as described & were installed easily. My only complaint is the amount of time it took to receive them. I ordered them on June 25, 2021 & didn't receive them until July 6, 2021.

Great tire for the price point. Looks good and has a slight tread patted along the shoulders for corner griping.

I used nail trimmers to clip all the little tabs off the sidewall. Tires weren't too difficult to mount.
