Hi,
Has anyone built and put some rides into a Carbonda CFR696?
Interested to get some feedback on it.[/quote]
Yep, 1,100km logged in the last 8 weeks. 90% tarmac, 10% gravel. Rides great on road, And on smooth dirt. I'm currently running Bon Jon Pass 35mm tyres, and it rides smooth, fast, and comfortably.

I averaged 28km/h on a 100km road ride last week. It's fun passing guys on 23mm tyres, they can't work out what my bike is or how it can possibly be faster than them :-)
Is it really 50 mm tire clearance for 700c wheels?
Yes, smallest measured clearance is 65mm at the chainstays. 50mm tyres would leave plenty of clearance for mud.
Frame build quality
Ride quality
etc
This is my first Chinese frame, so I can only compare to previous Giant and Specialized frames. The frame quality and tolerances are spot on. My LBS built it for me, and were impressed with it, and their mechanic has worked on all the big brands and plenty of exotic frames.

I had an Alloy Focus Mares previously, with the same tyres, and the geometry is similar. This frame is more comfortable than the alloy was. I feel like I could ride this on multi day bike packing trips, and plan to. 35mm tyres makes my Defy with 28mm tyres feel buzzy, the way my Defy made my old Tarmac feel when I bought it in 2015. It's mostly down to the tyre volume.

Based on discussions on the Riding Gravel forum the Carbonda QC is better than similar models from Workswell and Tideace.

Custom paint was only US$70 and looks superb. I've seen lots of great paint work on other CFR505's and CFR696's. Not sure how durable it is though. I have one small chip on the front already, just above the fork, and several paint chips where the chain has hit the underneath of the chainstay from chain slap or chain suck. The clearance with a 32/48 oval chainrings is a bit small. 50/34 would be better. I'm going to get an Ultegra RX800 RD with the Clutch to reduce chain slap.

I won't comment on offroad ride quality until I get some knobby tires fitted.

Have you done much climbing or hard sprinting with it? One thing I've noticed with my Workswell is rear frame flex when I stand on the pedals, to the point that I can hear the rear rotor rubbing on the calipers. Granted, I weight 220 lb, but I have not noticed rotor rub on other carbon frames I've ridden (e.g. Niner RLT 9 RDO).

I've been doing endurance miles, training for a 200 mile ride in 2 weeks, so I've only hit a couple of short pinches. I picked up a top 3 on Strava for a 67 second hill climb at an average of 510W, max 980w. I'm not getting any rotor rub or frame flex, whereas on this type of climb I can feel my Giant Defy flex in the rear triangle.

Alibaba for about US$700 depending on shipping, paint options, and frameset options. I used their headset , fork, seatpost, and seat clamp, but not their thru axles.

Sorry if the answer to this already lies somewhere in the thread already; I haven't been able to find it.

Is there an Open Mold version of the Open UP out there somewhere? I am talking about same geometry (including 420 mm chainstays), round 27.2 seatpost, internal cable routing, etc.? I have seen a couple offerings from Workswell and Carbonda, but those seem to have longer chainstays. I also found the one below with 420 mm chainstays, but it has a proprietary seatpost which is a no-go for me. So I am basically looking the same frame as below, but with a round seatpost instead. Help a brother out please :)
