Looks like TanTan finally has some real images of the FM198 up on their page now, instead of the 3D cad images. Geometry looks pretty good - not quite spot-on current, but not old school either - and it appears to handle 2 water bottles as well. I've sent off an inquiry for pricing this morning.

Has anyone been in contact with TanTan, or has one of these already? I finished a 936 build not long ago, which is now out on loan to a friend, and I'm looking at possibly adding the 198 to the stable if everything looks good.

Any thoughts/feedback is greatly appreciated.

I have found some photos and videos on their instagram @tantancycling
