technical street frame

Short chainstay and brakeless..

There are a few, and as always, it goes to what YOU like the best.

Fit Benny L has the most technical Geo and is easily the most responsive of most.

BSD ALVX this frame screams technical with the shortest backend ever on a street frame at 12.5 and a 75.5 head tube angle. So it's definitely a good choice. But most can't handle the shortness and end up looping out and over rotating a lot, not all though and you should get used to it.

Sunday Broadcaster V1 or V2. They both are real responsive and have Dent proof downtubes, they're great frames and the only downside may be the weight for the weaker people out there. The Dent proof is awesome if you fuck up grinds a lot.

Sunday Soundwave. Not exactly technical geo, but odds are you can still go rather tech with it. It has all kinds of stuff to prevent dents and if you wanna go big and have the only frame you'll ever need again, this is it.

FBM Hardway. Great frame, american made, awesome Geo. It's FBM.



Obviously there are more, but those are probably the BEST out of all of them.

And before someone gets angry and says the Soundwave isn't tech, consider all the people that get really tech with that frame. Geo isn't EVERYTHING. It's features help it maintain its techness.

75.5 ht angle, short chainstay like 13.25

I will say short chainstays like 13" to 13.5", depends on personnal preferences,
a good BB height, this could be a low 11.5" or a high 11.8", both are great, still depends on what you love.
For the heatube angle 75° is the good all around (from trail to nose manual) or a 75.5° if you want it really front twitchy but i don't advice it.
Don't try to shorten the top tube to earn reactivity, keep a comfy and roomy size, look better for short chainstays.

I personnaly ride a BSD beverage 21" (i'm 6ft tall) which is a really good all around/tech frame.
74.8 headtube
13.25" (slammed) -->13.65"
I like mine in the middle of the dropout around 13.4" or .5" but sometimes i nearly slam it to 13.3" (one halflink less) to make the bike feel like a toy, it´s funny.
11.5" BB perfect for me
And even if we don't care, 8.8" standover and 69.5° seattube angle.

The sunday broadcaster is the same thing with chainstays start at 13".
It seems to be a really good tech frame.

S&M Intrikat. Tech as fuck, American made. Designed for flatland, but in a 20.5, a bit long for it...
S&M BTM. Another tech machine.
Fit WiFi.
FBM Hardway.
So many out there...
But

Deco makes some nice frames for street and obviously federal Churchill will do you good
