Thanks, build went well.
My build:
Shimano 105 mechanical group set, Praxis crank, DT Swiss wheels all stolen off donor Specialized 2019 Allen Sprint Comp Disk with cracked seat stays I purchase on Craigslist for $300. Needed new set of pads ($60) and bar tape ($22) but otherwise everything was in good working order. Cabled it up with generic amazon brake hose ($16) and Shimano Optislick Shift Cable Set (R7000) ($24). Bottom bracket is the Praxis M30-BB86 ($45) because it needed to be compatible with the crank.
I had not read the advice here, and ran my cables from the back to the front. it was all actually fine, I mean it was a little struggle getting both the brake and the shifter cable through the bars, but it didn't take more than one evening of swearing. That seems pretty good based of some of the stories I have heard. Needed to drill out the front derailure cable hole, and ran the housing all the way to the shifter. From the horror stories I have heard, I was worried about shift performance all round but have been impressed, it feels snappier and easier all round VS the 10speed Ultregra I have on my other bike. woot!
Really enjoyable ride. fit feels good, reach might be slightly long, but will find out on my first long ride. Im 6'1", got the 56cm Large.
Only issue? creak. Ive got the bottom bracket creak. I'll be going through with a torque wrench, grease, and RTV silicone to see if I can chase it down. First ride was perfect (12mi) second ride it now seems to creak with anything above a light pedal stroke. Just like one click, but quite annoying. Hope its just e pedal or crank bolt or something... removing the press fit BB in there with Loctite Superflex RTV is not something I look forward to, nor is it something I have any idea how I would improve on re-install.
