Frame 2: The First Homebuildering

Based on my assessment with the Mark I eyeball, “that’s not going anywhere”. Nice job. Send it.

I love the new seatstay/pinchbolt design.

Do you get any visible amount of flex in the seatstay-mounted brake housing stop, from a hard squeeze on the lever? Your single tube is kinda slender. I would add a second tube to the same seatstay, so it’s triangulated in the plane of bending. Ignore me if this one is fully stiff enough.

Another trick I have used is make the “tower” or standoff to the housing stop shorter, closer to the seatstay, for less bending leverage. The brake is not very sensitive to having the cable come in at that slight angle. And a shorter tower is less likely to get bent if it hits on something, like from the bike falling over.

But I do sometimes try too hard to “optimize” something that’s fine the way it is.
