It would be awesome having the shifters and brake levers integrated. For now I think that is a good tradeoff, since I haven't found another way to get low gears without mortaging the house lol. Only think I'm wondering about is the bottom bracket. Looks like the Jamis uses a threaded BB? Any idea of it's the standard english threaded 68mm ? Would really like to get a chance to ride a renegade before buying the frame. The geometry looks really nice with the rising top tube and lots of exposed seat tube. Will probably test a Cervelo Aspero and Salsa Cutthroat too, just to make sure the Jamis is the right bike.
How does the Reynolds 631 differ from Reynolds 520? Got the Kilo TT which is Reynolds 520. Granted, these two bikes are very different geometries, but I'm guessing the Reynolds 631 is more compliant and lighter?

I believe the Jamis is still threaded I would be really pissed if not. The 631 is a nicer air hardened tubing based on 853 but not heat treated which all came from the classic and well regarded 531 that graced so many great steel frames for many many many years. I am unsure but I guess that the formulation of these tubes is different from 4130
The 520 is a lower cost Taiwan made Chromoly steel which is still made to their standards but is not heat treated or air hardened like 853 or 631. I would say 520 is probably a step up from generico 4130 but probably nothing super massive.
I would say potentially a handbuilt frame by a competent frame builder tuned to your specs in 520 might ride a little better than a stock more mass market 631 bike. However comparing both together as the same I would probably want the 631.
