What's a 20 degree setback post?

Can any owner of the SP-R088 make a video that reproduces what GCN does to show the flex of the handlebar/fork ? It will prove if it is stages or not.

Seems like I'm on a lucky streak with Tantan frames... bottom bracket sleeves got loose in the frame...

Hey everyone, long time lurker, first time posting. I’ve been between this R088 frame and a Tantan x68 for awhile now for my first Chinese carbon build. I was about to pull the trigger on the R088 from ali express because there’s a good sale going on right now that brings the cost to right around $600 shipped (about $200 less than the x68). Unit I saw the latest video from GCNTech with the dude who built up the R088 and shows a crazy amount of front end flex. He’s using a toseek integrated handlebar and to me it looks like a lot of the flex is just in the handlebar, but it’s hard to tell. I’m hoping if anyone who’s built up a R088 this past year could provide some feedback if they’ve had any issues like that. I don’t expect the stiffest frame out there, but also don’t want a noodle… Any feedback is greatly appreciated!

A few pages back some people were concerned about exactly the same thing. While I can't say for sure how noodly the frame is while riding outside, I am pretty confident that the flex shown in the video looked exaggerated, probably, as you mentioned, due to a lot of flex in the handlebars. I have done a similar test on my SP-R088 with HBR17 handlebars, and it doesn't look worrying to me at all (and definitely not as pronounced). Another person made a video a while back which also showed minimal flex.

There was also some top tube flex reported at the beginning of the thread; I am experiencing none of it. When I squeeze the seat stays, however, they appear more flexible with SP-R088 than on my other carbon bike (Velobuild VB-R-177).

I will report once I ride the bike outside, but inside, on the trainer, the frame itself has appeared solid.

Just check my frame and there’s nothing like the flex he was getting. GCN is sponsored by the ‘mainstream brands’ that builds like this undercut (Orbea & Pinerello etc). It appears the whole project is a scaremongering effort! What do others think that have completed builds and are riding their R088s?
