Thanks for your posts on this thread, I recently ordered this frameset at size 48.5, with clear coat UD gloss finish.
I do not have any experience ordering framesets from chinese shops/factories, but overall I am happy with the communication with Speeder cycling and the frameset itself.
It took 35 days from my paypal payment to the day where I received the frameset, which was less than I expected
I built the bike with parts from another frame that could not accept a front derailleur.
Michelin Power CUP TLR and Conti GP5000 S TR, both in 30 mm and installed on light bicycle WR45 rims, fit fine regarding tyre clearance. I might be able to fit 32 mm tires but I think that would be the maximum size.
I can confirm that the weight of the frame only (with hanger and cage mounts) was 906 g.
I did not order the integrated handlebar since I ride with clip-on bars mounted on a standard handlebar, but the top cover provided was not adapted to a standard stem. Eventually I fitted a FSA SRS headset, which look not as bad as I expected, as long as there is no spacer between the top cover and the stem
I was wondering if someone could recommend a rear derailleur hanger that could fit the frame ? I already bent one hanger following a minor crash. I had ordered two extra hangers, but I would appreciate having the possibility to find hangers without ordering at speeder cycling, if one day the shop disappears...
