I like mine. Hadn't thought of measuring top tube length. I do have the saddle far forward in the stock layback post (which I have never had to do before) and changed the 100mm stem to an 80mm. Mine is a medium and I am 5'11" with a 30" inside leg. I must admit that I would still like it to be 10mm shorter as I do feel stretched when on the hoods.
As mentioned, when I climb out of the saddle I do get a click/knock that seems to eminate at the BB area. I am 100kg so not too surprised. Bars/stem also creak when honking, though I think a rebuild with carbon assembly paste will sort that out.
A good light bike and well worth the money. I've read that the newer Nanolight isn't quite as good. Maybe too light for the low cost production?
I would recommend to anyone.
Mine has Reynolds wheels which are ok and for so few spokes don't seem too flexy considering my my weight. I have had 2 rear spokes fail (hardly surprising considering the ondition of the roads), but what I do find weird is that they have both broken at the threaded part as it enters the nipple. In my 20plus years of adult cycling I have only had spokes fail at the bend by the hub flange. When and if I get a job I intend to get some hand made, 32 spoke wheels built for it and keep the Reymolds as spares.
