Here are a few more pics

Nice, I like that you are offering the four TT sizes.
Is the rear end length measured to the center of the dropouts or to the very end of the dropouts?
-
The rear is measured center to center
-
Looks nice, you should offer it in that lime green.
Be very interested to see this come to life, my only niggle is the integrated seat clamp im not a fan of but thats just personal preference.
Good work!
-
please explain the choice of these angles
7 mm thick dropouts is overkil by today standards (don't the makers use treated materials for frame parts nowadays?)
is it not possible to get something more inside tapered regarding the stays/dropouts connexions?
ie below some work from Pir

How thick are the dropouts on frame in photo? We received input from a few people. Are specs are good or bad???
-
5 mm thick is sufficient. Also, the tapered dropouts are a must for todays modern rider. I would also recommend to make the rear end a bit shorter. 12.75 or so, center to center is good. Lastly, were you planning on including removable brake hardware? The 3D Pics appeared to have welded on guides & posts. Hope this helps...
-
Yes the brake are removable not welded to frame. Also the 3D drawing does not show it but the dropout area is tapered. On my 2D drawing the tubing size is small at dropout. Thanks for input. More is welcome
-
I think the dropouts are 7mm thick due to the chain tensioners going THROUGH the center of the dropout
curious what the weight is?
-
I personally like longer CS, any frame I've ever ridden below 13 I've completely hated - no good for back wheel tricks at all. 13.5 like the Rek frame is good. I'm not sure about the 68 ST angle either, might make getting behind the seat more difficult for things like cliffhangers and my experience with the quamen bowls frame also makes things like hang nothings more difficult.
-
Metalbmxer is correct. We started off with 5mm dropouts when frame was first designed. What angle is all around good? We will not know weight until frame is made. But I can ask manufacturer est weight.
-
Why are the seat stays, so long and extend up the top tube?
This material on the TT is thinner than the ST , creating a worse join.
Also the added material only adds to useless weight
-
The "truth" is, the probability that this frame actually ever makes it to production is around 3%.

Even lower now that the economy has tanked

When you talk about frame will never reach production those words are nothing new to my brother and myself. We have heard that over and over for years!!! Your frames will never make production!!! "Truth" is all the frame we designed made production. We now offer Aluminum, Carbon, Chromoly and Titanium race frames along side our 20", 22" and 26" street frames. You can see in pics below.
Truth is a small up and coming rider owned by brand .Sometime it takes Truth longer to get products then your major brands because we don't have 100k sitting around. When we invest money and time for frame design we try to come thru with product's.
We did flatland back in mid 80s it was fit to add frames to our product line.
The rear tri looks long but it's not only a 3D drawing. We have used same design on our street frames with no problem. Our race frames have upper tri into top tube with many years on track. And passed many test at the factory on frame testing machine over 200,000 cycles still holding up strong!! Frames weight is no more then your standard looking frame.
We are not worried about strength flatland frames are not designed for jumping 10 feet in the air.
Maybe I will get Brian from AFA to post about Truth street frame he has in hand. I was given good feedback from Brian
Thank you for all feedback. Truth want to offer flatland riders another good frame option
-
It would be nice to have another frame option on the market! I am looking forward to it!
About the angles: There are some riders who prefer 74 ° HT or even less, but many use 75 °. I would say with 74.5 ° you cannot go wrong.
About the ST angle: I would think about around 70 ° with the same wheelbase and so you would have a shorter CS. In other words: Shift the BB closer to the backwheel!
My personal opinion about the seatstays connecting to the top tube: If you are confident that it is strong enough I would say why not. At least it is unique at makes the frame different to all the other street frame looking options. It might happen that some people don't like the look of it...

I agree with everything daddy cool is saying. If you were to bump the head tube angle up to around 74.5 and adjust the seat tube angle to around 70 while keeping the wheelbase about the same so that the rear end ends up being a bit shorter (I usually prefer the rear end to be around 13", though a lot of flatland riders probably prefer even shorter these days) then I would be interested in buying one of these frames.
-
Agree with what others are saying...it's proven to be strong enough to ride street on so should be fine plus it's unique. I have seen one of the frames up close and it looks good. If a prototype doesn't work then the design can be changed. These guys seem legit so let's stay positive and support another company supporting flatland the best we can. I also agree the ST angle should be changed.
-
We can change frames spec easy. We want frames to be rider friendly for all riders. Frame will be tested on frame machine .If there is a problem it will be taken care of before production. I see there are 2 or 3 brands that have non street frame look and people are ok with them. Truth has supported AFA events in 2020 with no product on hand. Flatland sport is very small compared to racing but we are going do our best to support flatland . Here are a few pics of upper tri on our street frame

Here's a pic of sample frame. We are happy how It turn out. Frame weights 4 pounds 5 oz

Or did you decide to make any changes? If so what are they?
Any idea when they will be available for sale? I may consider getting one with a TT of 20.5. What colors do you plan to offer?

I have been looking for a frame for my BMX for a long time. Therefore I am grateful to you that you have a frame that I like especially well.
In this regard I wanted to ask if it is possible to paint the frame in pearl effect?
Many thanks in advance!

Frame looks good!

We did not make anymore more changes on specs. If you see something that might need changing let me know.
What color are you wanting??
Starting out in a new frame market. The frames will be made to order with 50% deposit. if order are place now frames should be ready and ship to customer in December.
-
Purple is always good hehe or a metal flake - just my opinion
-
Have you had one built up yet and test ridden? Be interested to see it and know how it performs...
-
We are trying to offer as many colors as possible purple can be one. The frame as not been built up. I am a old school rider from the mid 80s when quick spin and tail whip were the tricks to do. If i rode bike I couldn't do a single trick..lol. No pegs and platform
-
So its untested in the field as of yet...?
-
Great to see your work, keep pushing.
Frame looks great btw.
