Hi out there -

Anyone have any experience with this frame: https://imgur.com/a/RNUQv

http://www.ebay.com/itm/Thru-Axle-Carbon-Fiber-Gravel-Frame-Road-Racing-Bicycle-Frameset-OEM-Bike-Frames/263153129194

Anyone who is familiar with this design should know what its "based" on. (3T Exploro)

It looks like they have simplified the seat post securing method that was a big gripe on the reviews of the original frame. Also the rear dropout has an option to convert it back and forth between QR and TA. It looks like the only thing different in the TA and QR versions are the front forks. Weight is a bit more than the original 1237g vs 1150g (+87g more) - but totally acceptable given the price.

Looks like a fun potential project - just wondering if anyone out there has tried this frame or any similar versions of it.

Have you made any moves on this? I was just looking at this frameset over the weekend and would love to know if anyone has tried it yet. Seems rather new because I can´t find anyone with it in any chinese frame posts in any of the gravel forums.

I have had mine for a full season. I built it this past January. It has seen use a road bike, gravel 650+, monstercross trail bike. I have really enjoyed the flexibility of tire option and use.

Which frame is the one you have? It looks more like the Czech Merit brand than 3T with the cutout of the seat tube. Did you have any issues getting your position on the bike correct with the offset seat post that they send? 3T and Open use zero offset posts with this type of geometry.

Thanks!

Is anyone making affordable 12mm CX fork? I only find Hylix 12mm fork (flat mount) with "Max Tire width: 30mm"

Where do you buy Workswell frames? I see the WCB-R-146 on their web site but don't see it for sale anywhere.

They also give little information on their site:

http://www.workswellbikes.com/PRODDUCT/ ... 5/136.html

Is this the frame that is similar to the Open UP? Will it fit 650B mtb tires?

650b will fit according to description "Max tire: 700*42C and 27.5*2.2"
difference: openup have 420 rear-center and shorter wheelbase, this have 435 rc and longer wheelbase
similarity: asymmetric chainstay, bottle mount on top tube (but openup have more bottle mounts on downtubes)

http://ali.pub/1zgsqe - they don't have it in official store yet

you can try to contact them via email/whatsapp/fb:

Is there another open mold frame that matches the OpenUP geometry?

I do have the one that looks like a Merit/Tideace etc that I got of Ebay. I did find a bit of difficulty getting the right fit. A ~72.5 degree seat tube on a Small was a bit relaxed. I ended up using a Fizik Thar saddle that has a large/longer range of rail adjustment. I think if I were to do it again it would pick a frame like the Workswell WCB-R-146 with a conventional post and steeper seat tube angle (wasn't available at the time). In any case I have had a really enjoyable year of use.

For @drider85 or those with the Workswell 125 - are there threaded eyelets to hold fenders on the wishbone/crown of fork, and the rear bridge stay?

Anyone know which of these open mold gravel/cx disc frames is the lightest? I see the tantan cycling quote a weight of 985g (52cm) for their GR029 frame but I'd be interested in any real world weights. Cheers.
