My ChiTi frame arrived yesterday and managed to get it built up and maiden voyage today.
It's designed to be 63 degrees around a 140 fork, 27.5+ wheels. Inspired by the Mojo Geometron.
I decided to build it up with silly geometry and work back towards someting more sensible, just because.
At the mo it is the full 160mm travel on the fork, a -2 slackset. The static headangle is a daft 57 degrees.
Oddly enough, it rides just like a bike. A very fast, fun bike 🙂 I think I might just leave it like this.
Contrary to popular belief with slack bikes, climbing is fantastic. The long reach and steep ST mean none of that annoying perching the bum on the nose of the saddle to keep the front down. It's planted.
Downhill...well it is just a beast - so much fun especially on the steep stuff.

Is it broken? Looks ridiculous imo, and not good for the forks either.
That looks batshit crazy! Like it though
climbing is fantastic
Lol. Apart from when you come to a sharp corner.
What's the build quality like? How long do you think it'll last? Did you have to pay tax/duty and whatnot?
Loving the bar ends.
Did the downtube and top tube not get a MASSIVE pair of gussets? I'd be riding with a gum shield...
I want a go. Just because I'm slack curious....
Yeah, I would be a bit worried about the forces going though the headtube at that angle.
That is proper bonkers.
Looks crazy. There's slack and there's that!
Lol. Apart from when you come to a sharp corner.
Comments like this always come from people that have never ridden a proper slack bike.
Looks like a right laugh to me. 😀
Hmmm agree about gussets. Even my litespeed hmmer had a gusset and that developed a hairline cack.
Id be a little concerned about folding the frame..
One way of finding out....
Is that a leopard print seat? 😆
Looks like the headtube has already shearered from the downtube... almost prophetic...
Why the long stem?
Is it broken? Looks ridiculous imo
Cool, you stick with your Norba rig Ned. 😆
Agreed on the HT forces though, it does concern me a bit. The DT and HT are very beefy, but still...
I may carbon wrap it, just to be on the safe side.
And yes, the seat is indeed a denim and leopard fur wonder 🙂
That does look like a lot of fun 8)
Lol. Credit to the chinese builder for making what is actually a crap design. I'm getting a chinese ti built frame at some point. Designed properly though.

Crap how? Genuinely interested.
have you given it a name?
widowmaker?
emperor's new clothes?
you should definitely enter a few races on that, you're bound to improve your results by a place or two just by getting the front of your bike across the line before the guy next to you...although you will have started from further back on the grid, hmmmm swings and roundabouts....
63 unsagged is what, 65?
Not that bonkers and won't be unusual in a couple of years if things continue.
As built though, that is pretty extreme! Glad it's fun.
Crap how? Genuinely interested.
When it snaps you'll find out. Plus it looks gopping. Ugly seat, long stem, bar ends. That head angle and the big tyres don't tie in with the skinny tubing.
The only thing that's nice about it is the material used which is a shame as I like to see titanium put to good use.
🙄

If I wanted pretty I'd have bought a Ti bride not a Ti bike.

Have to agree, sorry OP but that's a shocker.
Looks a hoot - <doffs pioneering cap>
Wow.
A very interesting bike. I'm not sure it's for me, but hats off to you for trying something different. Hope it's worth it

That's one of the best forum replies for ages (still think you need to consider that gumshield).
🙂
I like it OP although the bar ends suck! links to the frame?
Ace. Not for me, but still ace! Have fun OP!
Interesting build. Proves my theory that a decent rider can ride anything.
Bedmaker rides the ring off his bikes, so how it looks is unimportant - it won't be a garage queen or leaning against a trail centre cafe.
The important question - is it going to be a SS in time for the SSEC though?
You've had the initiative and commitment to spend money on something different to see if it works. If it works for you that is brilliant and anyway, you are the only one who needs to ride it!
On the strength side,I probably would have gone for another couple of reinforcing tubes - one between the seat tube and top tube, another bracing the head tube, top tube and down tube.
I must admit I'm a bit confused regarding some of your component choices - e.g. bar ends and stem, I can't imagine how tall you are to make them both work as intended on something this long!
Anyway, enjoy it.
That looks bonkers in a fun way. Well done for trying it though.
Which chi-ti supplier did you go to and what was the experience like please?
the bar ends suck!
Bar-ends for climbing. When climbing (especially long, hard, steep climbs) it helps control, weight-shifting and leverage a lot with wrists rotated so thumbs are pointed up rather than in. Why do so many cyclists hate bar-ends so much? Is it purely a fashion thing?
Congrats on the new bike OP, hope it doesn't explode!
Looks fun my 456 summer season looks equally rediculous when in 160mode. I am eternally grateful for the travel adjust through.
Down hill is a hoot though
First impression is WTAF!! the second is 'maybe I like it a bit' then I feel a bit dirty but then again that never stopped me before, then I think 'no it's just stupid' and then I look at it again and think it looks like it could be fun...
I'm torn,,, so enjoy!
it reminds me of the 3 breasted hooker from total recall...
not pretty, but i wouldn't mind having a go as probably quite good fun...
Hmmm agree about gussets. Even my litespeed hmmer had a gusset and that developed a hairline cack.
I wonder if it cracked despite having a gusset or because of it?
It's not as simple as adding extra tubes and gussets all over the place with Ti. People who know a lot more about these things maintain that more heat around a Ti headtube can lead to more risk of cracking. Gussets may just move stresses to an even more vulnerable part of the tube.
That said, a 160 29er fork at sub 60 deg is asking for trouble. I just really wanted to try it out to see what it was like. The wheels were never more than 18" off the ground so not exactly going mental.
The fork is now a more sensible 135mm and the slackset out. Irritatingly though I ordered the wrong lower cup so will need to wait a few days for the right one.
Why bar ends? Why not would be my question. They add both performance and comfort benefits in one fell swoop.
Again, it's a tool not a work of art. Function trumps form.
It's a 60mm stem, hardly a monster. IT does seem to look longer in the pics though.
I got the frame from Waltly. The quality is superb. I've had Litespeed and Lynsky/On one in the past. This is every bit as good.
I half expected it to be a bit rough around the edges but it is excellent.
I'll put up some weld pics if anyone is interested.
Amy was great to deal with. The whole process was painless. All in price was £880 including customs.
And as for climbing, forget the 'slack bikes don't climb' myth that has been repeated for so long it's become 'truth'. It's not.
It's got a lot more to do with the ST angle than HT, along with reach.
Even with the bonkers fork, the ST angle on this is 74 unsagged. Honestly the best climbing bike I've ever ridden, no need to perch on the saddle nose.
Just grab those lovely barends, point uphill and spin away. Magic.
And yes Epi, it is already SS 🙂

Thanks for the pointers on how to use bar ends, I had no idea.
They are unecessary on a modern mtb with wider bars.
Each to their own though of course.

So are droppers, disc brakes, quality damping - they are all good though.
That looks like a long accident/recovery thread waiting to happen.
Quite like it... not far off my Last FF. Not having the bar ends or stem though.
If I wanted pretty I'd have bought a Ti bride not a Ti bike.
Thats one of the funniest things i've read on here in a long time. 😀

Be good to see a side on pic in "normal" guise too for comparison.
Post up pictures when the cracks develop please 😀

Ignore 'em - I bloody love it - slack HA check, leopard seat check - looks a shedload of fun! Enjoy!!
A few years back a mate, who at the time was sponsored by the big S as a R&D test rider, was ordering frames with 62? / 63? sagged head angles and ETT dimensions that were longer on his medium frames than on the XL frames. He was told by the "designers" that the market wasn't ready for anything like that because of preconceptions.
Now a few years have passed and long, low and slack is on trend. Give it a few more years and sub 60? head angles will be the emperor's new clothes.

That doesn't surprise me at all.
What really got me thinking was comments by Phil on the Mojo Geometron thread. Basically, slacking things off makes the steering feel slower, until the point is reached where flop factor takes over and counteracts this - making the steering speed up again.
I was keen to test the theory, it turns out it's true.
It felt odd for the first few turns, but very quickly became normal.
Mad in a good way!
Enjoy the new ride bud. 🙂
Wondered if Waltly, cheers for the info
Really good to deal with Andy.
I'm also waiting for a truss fork from XACD.
There's quite a contrast between dealing with Amy at Waltly and Porter at XACD. 😯
Yeah, heard that. Been thinking of a Ti Fargo for a while and seeing Salsas $2.5k price tag on the 2018 moddel makes me think going direct the only way will be viable!
Now looking positively normal with a 135mm fork, no slackset and a 62 HA.

Noice.
How long did you go on the reach and the chainstays? How tall are you?
450 reach.
I like a short chainstay but went 445 on this to keep it more balanced with the long front.
I'm 5'10, with shortish legs and a longish back.
Love the bike, love the Ti bride comeback even more. Fair play, fella.
Wheelbase around 1250mm ish?
Count me in the like it a lot camp. I think the plus tyres probably made more sense for a hardtail than a full sus. With 450 reach and 62 degree HA it's actually not too extreme numbers wise.
I'm glad to see more and more people experimenting with geometry and travel!
Would fit me nicely. I think I'm coming to the same conclusion on longer chainstays balancing frames with a longer reach and slack front. For going fast and for climbing especially.
I don't get the negativity here, looks great to me (apart from the bar ends, obvs).
Yeah, I make wheelbase about 1260.
Was going to give it a slagging but it looks great in the second pic and the welds look superb.
I've got a Singular Swift that I'd love in Ti - might need to look into these guys.
Enjoy!
If it wasn't for the seatstay/toptube junction I'd love that. Good effort!
bedmaker - MemberAnd as for climbing, forget the 'slack bikes don't climb' myth that has been repeated for so long it's become 'truth'. It's not.
Yup, I used to buy it too but my Ragley Ti (slack for the day, fairly standard now) is still the best technical climber I've ever ridden, it was phenomenal. I have a proper XC bike and it's better for just rolling up easy climbs but for anything else it's nothing like as good.
Thanks for the pointers on how to use bar ends, I had no idea.

Oooh, patronising sarcasm. And with blunt force. Thanks for the tickle
But seriously, how do wide bars replace bar ends? Wrist rotation? I was asking a real question! How do they 'suck'?
This thread is great, crazy bike, arguments about barends, great comebacks about ti-brides it has it all.
I like how it looks a good deal more in the second set of pictures - it freaked me out when first posted.
Its hard not to love a bike with that saddle on it though 😀
But seriously, how do wide bars replace bar ends?
[trying to be helpful] If you're doing push-ups, it is mechanically easier (up to a point of course) to dip lower with your hands planted wider apart - your body comes down towards the floor between your arms more freely. With a wide bar, you can shift weight forward by pushing your elbows down and bringing your chest towards the bar without your shoulders collapsing and rolling forwards. If you keep tension across your upper body, you're actually in quite a strong position and it's easy to get there. Don't know. Something like that?
^thnks BigDummy. Though I still think that's an explanation/of sorts of one virtue of wide-bars vs narrow bars, rather than anything to do with bar-ends?
... (cont'd)
The best description I've read that explains a basic advantage of their use (I can't describe it nearly so well) is this from [url= http://www.bikeforums.net/mountain-biking/143901-noob-question-what-benefit-bar-ends.html ]Bike forums[/url]
Barends turn your wrist so that your thumb is pointed up, this means that your radius and ulna are oriented so that the biceps muscle in your arm has greater mechanical advantage than it does when in the palm-down standard riding position.
For me it's not just the extra leverage and added comfort. but the ability to hoist chest forward without straining wrists, so to give even more pedal-torque from body-weight, while simultaneously driving the back wheel into the surface. I mean on seriously steep stuff. I know that they (bar-ends) can ruin the nice lines of a blke aesthetically, and in that maybe that sucks if you're that way inclined, but I've yet to try any bars without ends that that get me up a hill as efficiently and comfortably as with them. Same with push-ups, some prefer push-up bars, some not. The choice of positioning push-up bars wide or narrower is a different discussion than the choice of push-up bars vs none? Of course, YMMV - as with push-up bars (see below). I like options and I like simple lines. When I've chosen not to fit bar-ends on MTB bars I'm aware that it's simply because I prefer the look of the bike without them, not because I'm gaining a mechanical advantage/increasing my options by [i]not[/i] fitting them.
I believe barends can also engage your lower back more effectively, for when you do need to put a bit more power down.
Nice bike btw 😀
Have to agree on the saddle tho. Any bike looks good in those 🙂
Really, really like that. I'd have something similar, with slightly shorter stays, if finances allowed. The best technical climber I've had was a Ragley Mmmbop that I put a -2* angleset in (static headangle became 63*, with a 140mm fork, according to a phone app). Could just have done with being a touch longer in reach.
Mmmmmmmm Ti welds.....
looks nice to me, more so in the second set of photos.
Bar ends are great IMO.
First big test yesterday, Torridon big loop in glorious conditions. Full Coire Lair and Annat descents.
The bike was ace, and I didn't die in a hail of Ti splinters.
The MRP fork is remarkable, it is so nicely damped and soaks up everything with little fuss. I tweaked it a bit but ended up with the Ramp fully off, just a couple of clicks of rebound and low speed compression about a third of the way on. The air spring pressure is also way less than recommended in the book but I never bottomed it out.
I now have it set at 150mm travel, where it will now remain.

I decided to bow to pressure about the barends and have now replaced the cockpit with something a bit more moto 🙂

Nice one John...just wait for Porters forks...then you'll have a proper bike...none of this suspension nonsense!
Time to tickle the full Ti frame itch me thinks...
Jesus christ bring the bar ends back!
Bars aside, I likes it and I bet it's a riot to ride.
Does the clock work?
Ooh, never really considered chinese titanium but those prices are almost palletable compared to american and others frames.
Where can I get the stringfellow saddle though....
Taped on cables?
