• Did you pay 499+shipping only or was it any "hidden cost" or additional costs that appeared on the way?
I paid 499+160 for shipping (XDB). No more costs for me like taxes or customs. (I live in Germany.)
• What is your tire width?
Currently 28mm on 21mm inner width rims. But there is plenty more room, I think 32mm should also fit.
• Is it the default handlebar?
Yes.
• Did you have any kit during the building phase of the bike?
No special tools required, you dont have to press in bearings etc. Hardest thing for me was routing di2 and hydraulic cables through the handlebar.
• Which size did you go and what is your height?
I went for Size 54 (M), but my old bikes all were Size 56. I am 181cm.
• is it possible to swap the handlebar to another one if I dont like that one?
I think only the "Talon 1 Piece Handlebars fit". But you have a lot of choice in stem length and width on the vb site. Also on aliexpress there are alot of these bars in different sizes. All models for F12/F should fit.
• did you guys got any discount?
No
• how much did he charge for the paint? Different paint, different price?
I dont know, I didnt ask. Went for Matte Carbon and I think it is beautiful in the sun.
