Nice looking bike. What's the build specs? Looks like a mix of shimano and chinese parts?

Friend there are two seller on Aliexpress selling as Sp-cycle. Do you sell on Aliexpress? Your warranty is valid buying from there?

• The derailleur pulleys are different sizes: 12 teeth on the guide pulley and 14 teeth on the tension pulley. They also run on sealed bearings and spin freely which is nice - one thing that really irks me about 105 is that Shimano uses pulleys with only bushings and they always seem to gum up.
• The thumb shifter is matte plastic rather than glossy, and it doesn't have any branding on it. I like this - it's grippier than a glossy coating.
• Both right and left brifters have retention clips for the hydraulic lines that prevent them from swiveling outwards. The clips are retained by two 2 mm screws in the rear of the body; when they're unscrewed the clip can be popped out and the lines can swivel outwards for easier installation if the hydraulic lines foul on the bars. But if the lines don't foul, I'd actually keep the clips in because they retain the nut so you only need one wrench to install the hydraulic line instead of two. This seems to be different than previous versions, or maybe just the carbon version? See Trace Velo's video here: https://youtu.be/NKNcKwiH6v0?t=928 where the nut seems to be held captive by the shape of the brifter's body rather than a separate retention system.
  
  
  
  
• The shift lever has a 1.5 mm grub screw at its base which adjusts the shift paddle position independent of the brake lever. There's a ridiculous range of adjustment, way more than would ever be realistically used, but hey it's there anyway.
  
  
  
  
• I screwed in the free stroke grub screw to see if I could replicate the rattling issue, and I wasn't able to, but maybe this will be an issue when the brakes are all set up.

1.  My biggest complaint is that the unit's GPS stops recording at 2mph.    (Others have stated that other brands do the same thing, so who knows if this is just me going to slow.)  I have spent a lot of time walking my fully loaded bike packer up 20% and greater climbs.  It is frustrating because the iGS630 stops recording the climb and auto-pauses.)

3.  iGS630 always seems to have a different elevation gain and mileage than Strava on my Cell phone.  (On a 50 mile ride, iGS630 will be different my 2 miles and elevation will often be 100s of feet less climbing.   (I need to look into how to calibrate my current altitude. Maybe this is why.)

4  There are almost too many buttons on the unit and too many different screens and functions.    I wanted to be able to quickly use it out of the box, and really need to re-read and remember what buttons and screens do what.

6.  I am still trying to figure out how to upload a GPX file to the App, then to the 630.
