Hi guys,
Here is my R52D. After 3 months, the frame arrived well packaged, no missing parts. The finish, build quality and tolerances are great, BB and disc brake mounts are faced, head tube well finished, the paint job is excellent with no excess in the BB, disc mounts and head tube areas. No any particular problem during the build. The frame, seat post and handlebars have marble glossy finish, and look nicer than the pictures. The size is 510, handlebar 370|85. The frame feels stiff, the seat post has good flex and is comfortable. On the other hand, the handlebars are very uncomfortably stiff, may be because they are very narrow, 370 mm with short stem, or they are just stiff. I installed GP5000, 28 mm (real width of the tire is 29.4 mm), on 21 mm internal width rim and there is 3-4 mm clearance on the chain stays, the fork has bigger clearance.
My only complaint, it is not about the frame but rather about my handlebars choice. The handling is very very nervous. I have two another bike with 400 mm handlebars and 90 mm and 100 mm stems and the handling is very different. So, I was wondering, could the 30 mm shorter handlebars impact that much the handling? I'd like to ask the other frame owners how they feel the handling of their bikes.
