Currently building up this Seaboard GR02 for a friend and wanted to share my first impressions. She's currently riding an older aluminum, Specialize, rim brake road bike that is a little too big for her and maxes out at 700x25c tires so I think this should be a big quality-of-life improvement. While not serious cyclist, her bike is her primary mode of transportation and she often rides 50+ miles a week between commuting and errands. 

The build went smoothly. The plan is that it'll be a super commuter/all-road bike. There is absolutely nothing particularly nice or special about this frame, and a few things that feel cheap. It would have been nice if it were nicer but it should get the job done with is all I want/need. I don't love the braze-on on the chainstay for the rear shift cable, I wish it was set up so you could just run shift housing through the whole length of the bike rather than having the stops and starts that expose the bare cable. The method of clamping the brake hose to the other chainstay is also a bit dinky. It's just a little plastic clip that is held on with a stumpy screw. One of those zip-tie braze-ons might have been better. Nothing was faced which is 100% expected at this price point. I like that the cables are mostly externally routed. For someone who is not a serious bike enthusiast, I think having internally routed cables on your commuter would just be annoying. Seaboard claims 42c tire clearance on this frame which I think is much too tiny for gravel but totally fine for all-road-commuter+. It also has rack and fender mounts which was a must-have for this build.

In some time, hopefully my friend can give me some longer term feedback about her experience with this bike because it seems like it has good potential as a frame for all the folks looking to build bikes for their friends/family who they want to have a decent bike without completely breaking the bank.

Frame (size 44) was 1577g and Fork was around 475g before I cut it. The bike with my wheels is 18.5lbs but I think once I put the Serenade ones on with fatter tires it'll will go slightly over 19lbs/8.6kg.

I can't say anything about ride quality because it's at least two sizes too small for me and I am also still waiting on the wheels to come in the mail, the photo shows the bike with my road wheels that I temporarily put her parts on just so I could get the drivetrain set up.
