TanTan GR257. 57mm clearance, UDH hanger, storage box etc just released.

[Eisenhut]

I had my mind set on the Veloaero Grav then this came out. A bit shorter reach could suit me.

Anyone else who pulled the trigger?

It's basically the same frame as the Mondince FM346 (except for the seat tube shape/profile, but the geo chart is the same), discussed in this topic: https://chinertown.com/index.php/topic,7193.0.html


This TanTan frame was also mentioned here: https://chinertown.com/index.php/topic,7298.0.html

Looks like they don't make 61, same as mondince

it's a pitty, I liked geometry of 61mm better

I think it looks identical, maybe the profile looks different just from the photo?

Top tube / Seat tube junction is different. Tan Tan appears to use a wedge whereas Mondince might clamp from the back as it looks like the seatpost sits further forward from the back end of the top tube.

I asked them and they told me the 61cm is likely months away. I ordered the Velobuild instead. Maybe I'll try this frame as well when 61 is available.

They will probably never make one. I've had a couple of instances when the geo chart was showing xl/xxl chart but when I asked about it it was always "coming some time in the future" and it never did. If they don't have the mold now, they most likely never will.
I really like this frame but have to look for something else and unfortunately there's not a lot of choices in my size.

It looks like the storage box is the older style used on mondince 326. It seemed like it could be problematic opposed to the newer style that uses the magnets...

Tan Tan just released a video with complete bike build using this frame

What could be the problem with this kind of storage cover?

I just pulled the trigger on a GR257. Having them build it with a di2 groupset, custom paint, no wheels (will use Elite wheelset), custom paint.

Will let you know how it all goes.

size 61(XXL) is now offered by meiner https://pl.aliexpress.com/item/1005012861779650.html
It has a slightly different seat clamp design
