Rims are in hand.
105 FD is in hand. Spec says it can handle a 16t delta, and that's what I have.
Looking at 105 5800 RDs. I'd like to have silver, but they appear to be vaporware. Would look nice with the hubs, and crank. Still waffling on short cage which gets me 30-28, or medium cage for up to 30-32. My local cycling bud tells me 30-28 will get me up any grade, but he's 28 years old and 140 pounds, whilst I'm 59/192. Kids.
Next up: spokes. Wheel build commences as soon as hubs and spokes are in.
Still working on stem, seatpost, chain, fenders, cassette, seat clamp, tires, spokes.
Unfortunately I can't do any building until I find someone to face & chase, unless I decide to skip it.
