Re: Carbonda 505SL Integrated Stem I received my CFR505-SL this week, building up with Shimano GRX810 2x11. I've never been disappointed by Carbonda, and pretty happy with the quality on this one. They did forget to include my seatpost clamp, fortunately have a spare in my parts box. Will post more pictures later.

I've built up many frames up over the years, this is the first using an integrated handlebar (the CGB02).

Differences between CFR505-SL and CFR505:
  • Headset size: 1-1/2"* 1-1/2”ACR (two 40 x 52 x 7mm: 45x45 deg bearings)
  • Rotor size: 160/180 mm
  • The rear brake cable exit was changed to the same design as CFR707
  • The front derailleur cable routing was changed to the same design as FM1056
  • Seat tube was changed to normal seat tube clamp design, same as CFR696
  • Removed rack and fender mounts. Only keep two sets of water bottle cage mounts. (My frame has 3 with the downtube mount)
  • Max tire size:700x42c  / 650B*47c
  • Max chainring: 50-34T / 42T
  • T47 bottom bracket
  • All mounts removed from fork. There are internal and external routing versions.

Build Notes:
  • Rear caliper: flat mounts on the chain stay are 25mm thick, so if you're using Shimano calipers & SM-MA-R160D/D adapter, you will need 38mm long bolts (Shimano part Y8N208020)
  • Headset bearings: Don't quite trust the quality of the supplied bearings, and considering what a PITA it will be to replace the them, I plan to order new Cane Creek or Enduro bearings for the build
  • Front derailleur: cable uses housing from the shifter to to a plastic guide below the BB (pic attached). From there it's inner cable to the RD. You'll need around 1.4m of housing
  • Rear derailleur: cable use housing from the shifter all the way back to the rear derailleur. I'm using a GRX810 RD, so I need to use the flexible Shimano OT-RS900 housing where the cable exits the frame to the RD. I'm using a Jagwire Double-Ended Housing Connector CHA062 to join the two cables. Note the Jagwire Pro cable kits (e.g. PCK500 ) also include the flexible cable section and double-ended connector.
  • Get some Internal Housing Damper foam (6mm ID, 10mm OD) for the rear brake hose and shift cables to stop it rattling in the frame. I have some made by Jagwire (ZSK600), you'll need around 2-3m

Re: Carbonda 505SL Integrated Stem Got my CFR505-SL built up yesterday with Shimano GRX810! Still waiting for my wheel parts, so using a spare wheelset with 32mm tires until they arrive.

Did the inaugural ride ride today which was cut short by a slipping seatpost >:(. Carbonda forgot to include my seatpost clamp but immediately sent me one, which is in the mail. I'm using an old spare clamp I had, but it has never gripped well, even if the seatpost is slathered in carbon paste.

First impressions are that the bike is very comfortable, absorbs a lot of vibration from the road. I ordered the 420x90mm integrated handlebar, and I have to say the top is kinda narrow. I would say get at least a 20mm wider bar that your normal bar width. The drops are wide and very comfortable.
