I'm not too sure yet, their bike frames cost 260 Pounds as a starting
price. So I think my uni frame might cost around 100 if it's going to a
fair price.

What has been the break point of other frames? Or the problem point of
other frames? That is probably the best place to start. The other thing
you want to take into consideration is how much clearance you want and
in what form. Do you want a form fitting frame similar to a rounded
frame, or do you want a flat top. You seem to know what you want in
terms of a bearing clamp so really the things to look at are: basic
frame design (single piece, hunter style, or reinforced hunter style
which I think ryan used to have and Jeff Groves is still riding), and
crown style.

Going by flat top crown style on a basic single piece frame, there are
three major styles I can think of, "flat" top (Torker DX style),
"round" top (Koxx signiture style), and "post" top (Yuni style
frames).

Are you having a problem with breaking frames? Bending them? Are they
too heavy? The best way to design a frame is to find out what the
things are that make you not want to use a production frame. Not just o
I heard this is bad, or this one is ugly, but what is it that makes the
frame a bad one.

I would think that a good frame would be a lot like the 2005 KH frame,
only perhaps more reinforcements around the crown, and knurling on the
crown. seeing as your having it made, you might as well get a long seat
tube also. minimal tire clearence would be good also.

that's about all I can think of.

Minimal tire clearance is something I would actualy stear away from for
a trials frame as you are very likely to knock your wheel out of true
if you are killing frames, also knurling is something that would weaken
a crown and is something that is definatly not needed for a trials uni.
But yeah your suggestion of a long seat tube seems like a good one, I
would imagine that that is probably a large thing that most trials
frames havn't even touched.

ok, I thinkt he reason why there aren't long neck trials frames is
because they would most likely have to have different size choices and
short people still might not fit on them.

maybe extra reinforcers around the seat crown then. If it's for pure
trials a round crown frame will save you alot of bruised knees also.

ntappin, I'm having this custom frame made because I have seen faults on
previous frames. Joe Hodges is having a chip in on this frame design,
as he wants a frame that won't break on him, even though he's getting
an XTP.

However, its just something I wanted to make, so possibly, with more
interest, Iolobikes can custom make some more uni frames for other
people, at an affordable price.

However, i am still stuck on what sort of frame style I want. I don't
think I want the Devil type, I'm kinda thinking between the KH 2005 or
KH2004 frame styles (whatever the proper names are). More suggestions
are welcome.

Also, I have taken into consideration, the break points and the
weakspots on some trials frames. The Nimbus II frame's weakspot just
below the top of its legs, and the KH 2005's weakspot at the weld
joining the seattube to the rest of the frame.

I'm mainly a trials rider, but really wouldn't mind being able to do a
few flatland moves like 1 footing etc. So I think a flat top is best,
but now comes the hard choice, what kind of flat top do I want? :o

EDIT: could someone maybe show me pictures and describe what a "single
piece", "hunter style", "reinforced hunter", or "crown style". I
probably know what they are but just haven't really used these terms
often.

Itake it you want a squareish crown then?

also, does iolobikes make titanium frames? I'm not sure how strong a
titanium frame would be, but it would be aweosme to have a titanium
trials frame🙂

Yeah I want a square/flat top frame, but there are SO MANY different
types out there. I just had a look at the Koxx Signature alu frame,
then at the KH'05, KH'04, and Devil/Nimbus. This is where I needed
other peoples' help, to choose a design.

No, Iolobikes don't make titanium sorry, only T45 steel fillet brazed.
(which is incredibly strong itself). However, I do know several Russian
brands that'll be willing to make titanium frames, but they cost a
bomb.

yea, personally, I think a steel/trials version of the koxx sig frame
would be awesome for street and trials.

Hi there,
If you want to learn a few flatland moves, it usually means that you
will end up learning quite a few- so right there and then i would knock
out the options of hunter style ( multiple tubes from bearing holder to
seat post on each leg of the frame) or round crown. I think the long
seatpost idea is a good one- a seatpost (unless its a thompson) will
die before a frame does. So cut out the weak spot and make your frame
have less seatpost to potentially bend.
This also makes it easier to do stand up wheel walking and frame based
skills (no pesky seat post clamp to get in the road)
Also take into consideration seat post size- 22.2mm is too flimsy to
withstand learning crankflips or some bad bails.
It seems that you are not a rider who is only going to ride in one
discipline (trials/street), so making a dedicated frame for one of them
may leave you dissapointed when you want to expand your riding style.
Might i suggest not making the frame overkill with large gauged tubing
and gussets- less can be more, and if it doesn't last your riding it
seems as though you can just get it fixed.

Have fun! and post us pics if the project goes ahead

Thanks for the comments and ideas so far, I am definitely having it a
big seattube size, like the 27.2 or so on the KH 2005, so i can use my
Tryall post and Koxx1 clamp.

Still, I don't have a clue what hunter style or reinforced hunter etc..
all look like, do you think it's worth getting the frame done in the
way that the Koxx Signature is done?

EDIT: I am really a pretty full on trials rider, who's almost totally
talentless when it comes to freestyle stuff. I just think having a flat
top would be good as a mess about kinda thing, like 1 footing along
skinnies perhaps.

I agree here. I've got an uncut 300mm seatpost maxed out on my Yuni
trials frame and it's still a bit short for my taste. I'm a tallish
(6'😉 guy who rides SIF a lot and I'm finding that I have to hunch over
a bit to hang onto my seat.

Do you have any evidence to back that up? My Yuni trials frame takes a
22.2mm seatpost and I've beat the living hell out of that thing with no
problems. I've broken several seats and am now riding on a CF seat
base, but the frame has yet to bend or break anywhere. Is an extra 3mm
of diameter going to make that huge of a difference?
