I wish I was building a bike right now. So many good options on the cheap! Lol

2) When it comes to the setback, what matters is that we can achieve our preferred saddle position relative to the BB. This in turn can be determined from just 2 factors: The seat tube angle and the setback relative to the line through the bottom bracket. The reason the setback looks big is that the seat tube is shifted forward relative to the BB as seen by the blue line.

i) My current bike has a STA of 73.5 instead of 73 on the Graro. That results in shifting the saddle back roughly 5mm at my saddle height, relative to my current bike.
ii) My current bike has a setback of maybe 5mm, (round seatpost centered on the BB). This means another net 15-5 mm = 10mm setback.
iii) However, the clamp that holds the saddle rails is also much smaller on the Graro, which gives a bit of leeway the other way (roughly 7mm by my estimation).


I've concluded that I can easily achieve my current saddle position, even without slamming the saddle all the way forward.

Thanks! Curious what saddle you are using, as it is always nice to have a bit more adjustability. It's hard to compare saddle rails from pictures, especially since we're after the length in the back as you said and not the total length of the rails.

Not sure if this prognosis is exhaustive, but there is probably a problem with 1 of the 14500 batteries I had on my bike. Just compared two "new" 14500 batteries which were giving ±4 volts. The ones installed were giving ±3v (which apparently is the cutoff?) and ±3.5v.

But upon inspection it seems like my expander plug did not move, but just the stem maybe? I'm not sure if I should add some carbon paste on my stem. Anyone has suggestions?

Been a while since I built up a bike... not done an internally routed one before. Seems fairly straight forward but just wanted to check especially with those who have successfully built one of these.

The bike came with two teflon cables already inside the frame ( white cables) one for rear brake and rear mech, but not front mech and not front brake. They are just about long enough so the ends protrude out of each end of the hole - what's the deal with these. Are they to use as guides or can I use them as cable housing? They're not long enough to reach the bars so i'm a bit confused here. I could extend with a bit of compression less housing but this doesn't sit right with me.

Will the bars allow 2 x cable housing internally on each side? The inside seems a bit tight using RISK compressionles housing.

The exit holes for the rear mech and rear brake has no grommet. Is this right? Just seems a bit cheap...

In my opinion the seatpost does not sufficiently filter the roughness of the road but the tires compensate (5.5 bar with TPU inner tube at the rear and latex at the front) but I don't like it either when it's too "bulbous".
