would love to help, but it would be helpful if you could narrow down your requirements; eg: 17.9 - 18.5mm or 18.5 - 19mm top tube; straight tube design only, double-triangle diamond frame only, or bendy frames only; BB's prefrences - euro, spanish, mid or usa ......etc.

some people here would consider the hoffman's strowler light, but for others anything not titanium or double-butted, alloy/ ti locknuts and bolts is heavy, so ... ...?

The St. Martin Class X2 would be a great choice also. $199 at flatlandfuel.

i'm using the st. martin effiel now, 18.2 tt length, spanish bb. was a mid-schooler who just got back into flatland, so my area of knowledge in regards to frames is relatively dated.

i find the Effiel frame a-tad flex-y, especially around the bb and rear dropout areas. the Diamond frame (which is the straight tube 'kin' of the effiel, so to speak) should suffer from the same maliase as they share the same dropout and bb design; i stand to be corrected, diamond frame users pls feel free to chime in.
the welding on both my frame and my gf's effiel were good and on the diamond frames that i saw, quite unlike TJ Perry's experience.

Hey, thanks for your answers.
Now I checked the frames.
From design I like most the Suelo Simple (1795 g, 18.8" TT)
The St. Martin Class X2 is available with a 18.1" TT (1810 g)
And the KHE Paris 2 is the lightest (1550 g, 18.8" TT)

What are you thinking about the Paris. I read really good and really bad things. Anybody who has experience with it?

I also read that the length between the seat and the bar doesn't depend only on the TT. Is that true? Do you think the Suelo is a big frame or a small one?

Sorry if my questions are stupid and thanks for your help...

i wouldn't recommand khe fames as their frames (here in globalflat) have a reputation for cracking, and resale value for khe's are low.

i had a g2 quamen, enjoyed my time with the g2's, and the reviews for quamens are generally positive, and their resale prices are steady; so my vote is for the quamen cypher.

yes, the lowered tt of effiel, at 18.2" feels alot roomier than my ares choosie at 18.5". the off -centre seattube of the cypher will also have the same effect (roomier) versus a 'normal' straight tt frame.

www.g-sport.com - george french articles help me find way in this new age of flatland, i think they would be of great help to you too.

all the best,
kelvin

view the clip above with a caution. it could be a case of brand sabotage...

in all fairness, patrick schoolon at flatlandfuel stated in a previous thread (use the search button <paris 2 breaking/cracking>) that the frame warrenty claims on khe frames through flatlandfuel are slighty lower than average (if i remembered correctly, and it means khe frames are more durable in reality than internet-ality) when compared to certain brands sold at flatlandfuel...

the Palmero has the 18.6" TT and a 13.38" rear end.
your Dafunction has 18.66" TT and a 13.46" rear end.
the palmero has a slightly steeper HA at 75 degrees and
a slightly mellower SA at 71 degrees.  weighs 330 grams
less.
i weigh 200 lbs and this frame is strong.
i highly recommend it.
