C&V Inspired NBD: Custom 26" Drop Bar Build
My latest build, a custom 26" or Rene Herse 'RTP' frame and fork sporting Humptulips Ridge tires.
My previous personal bike was built with 'superlight' 7-4-7 tubing, 650bx45mm (actual) max, titanium bits and bobs to save weight, the result felt a bit precious.
This bicycle was meant to be quick and dirty. The frame is built with new Reynolds 531 8-5-8 std. dia. tubing, lightweight Reynolds seatstays, and Tange bent chainstays for lots of tire clearance. Socket style dropouts and fork ends are easy for fabricating. Fillet brazed. Pacenti fork crown. I pushed the head tube angle to a slackish 69.5 degrees, with a 46mm fork offset, highish trail, meant for stability. 26" wheels still feel very practical in my mind. The XO-1 was a large inspiration for making my own frames.
The build is nothing stupid, meant for practicality:
Crust Shaka bars
Origin8 Classique levers
Shimano 9 speed bars ends
Nitto Technomic stem
Tangle FL250C headset
Paul Neo Retro & Touring brakes
Brooks saddle
Thomson Masterpiece post
Shimano UN55 118mm BB
SunXCD crank
TA 46/28 chainrings
Shimano Dura Ace 7700 front derailleur (a bit precious)
Shimano XTR 952 rear derailleur
Shimano M770 11-34 9 speed cassette
Shimano XT 737/738 hubs
DT 15g spokes
Of interest, Sta Tru TR25 26" rims, rim brake and tubeless
Rene Here Humptulips Ridge tires, 559x52mm @ 20 psi
RAL 1027 color code
I've only taken one or two shake-down rides, but it does feel stable, lively and fun. The tires do feel fast, and are quiet on pavement, I have yet to set them up tubeless, a must. I am excited to ride more!

Devin, are you the frame builder? Beautiful bike. Love the color scheme, plus it'll look better with bits of dried mud and clay!

That ticks every box... The mustard glazed fillet brazing looks amazing.

Thing's an absolute killer. I got wide-eyed looking at Jan's Oregon Outback bike, and your build/frame is no slouch in comparison.
How do you like the shifting on the 46/28 crankset? I've been mostly fine on a 47/30, but thinking about an upgrade to a new crankset and I'd love some lower low gears.

Just perfect! Would a 531c decal at the top of the seat tube spoil it?

Perhaps a customized 'stealth' decal?

Yeah, dropped chains can be a real bummer, especially cresting a big hill as you're starting to get some momentum going again - ya try to flop it up to the big ring and it overshifts the chain onto the crankarm. I've played with FD position and limit screws so that these missed shifts have become rarer, yet they always seem to happen at the most inconvenient times. Luckily, I don't race, I don't hold myself too accountable to personal best times, and never really mind a little breather at the top of a hill anyway.
