Well I'll toss
Bellatisport in the mix.
Before ordering I scoured the net looking for info and feedback and was a little confused by what's out there. At the time I was looking for a good price on Colnago C64 disc---found that with Bravacycles which I think is legit and no issues---however, I decided on a Cervelo S5 disc from Bellatisport b/c the price was just fantastic and in stock.
Based in Switzerland and it appears to be a shop for great prices on closeout or new old stock. They do have current products, too. No issues and prompt communication with Andrea Bellati-the owner. Facebook page etc. Anyway, got my S5 in about 12 days from Switzerland to Texas, door to door. No VAT, No duties/import taxes, etc. Tracking code from Swisspost carried over to USPS with full updates through to US customs, after that only on delivery. Just a great deal on a new in box frameset never opened. I would not hesitate to buy from him again. I have no idea about warranty and all that biz---worked in a shop for 8 years, been cycling for 40+ years and never warranteed anything so not a major concern for me. YMMV.
Ordered lots more parts from different vendors -- most everything here on time but I will say be careful of some online retailers claiming "in stock" status when all they are doing is drop shipping from the distributor or mfg warehouse. That's fine except if the warehouse is wrong then you've been waiting on a lie essentially. Many suppliers are playing catch up now in a post covid economy.
