Greetings--this is a "review in progress," since my kit was delivered some time ago but I have not been home until this weekend to start assembling it. FWIW: For those (like me) without smart phones, QR codes are not the most welcome way to deliver instructions! I was able to borrow a friend's Iphone, but.... So far so good, apart from a question as to wheel size. I ordered a 27x 1.25, the size of my old front wheel and tyre. When, earlier today, my bike mechanic mounted a new tyre of that size, it popped off of the rim at less than 70 PSI. I noticed, too, that my old rim can fit snugly within the new one; it's almost as though I have a gravel-grinder wheel now, rather than the old skinny road one. We will try other tyres until one works--and if none do, I will let you know. All parts arrived in apparently intact condition, so thumbs up in this department. FedEx took their own sweet time about delivering, but both packages arrived in good order--all good! I will keep you posted about the wheel/tyre mystery and abut how the bike turns out. Thanks!
