63° but once sagged or deep in the travel, the difference won't be noticeable.

Mini 2 days trip +3 000m elevation in the French Alps

Everything to sleep in a drybag under the downtube.
650 mL of water ( :o )
Food and night clothe in the framebag.
Rain vest in a food pouch of the handlebar.
Rain pant in a ziplock under the saddle.
All the tools in the One Up pump.

Nice build.
Short reach, 73° STA, 67° HTA, long chainstay and small BB drop.
It looks like a marathon xc bike rather than a pure "down country" (NS Bikes Synonym, Transition Spur and so on).

Yeah, it looks great. What is the naked frame weight ?

35
There is an air valve that allows to use a rigid bottle (PET, water bottle or metal like mine).
I find it less hard to pump than a bladder in a framebag.

It is a bikepacking setup, I won't use it on day trip.
I also use it while hiking.

I live in an area with lots of flats, so 32-34 ring would be essential.  Still, if I can get close to 430mm chain stay length, I should be good.

Is this chain ring clearance something that Titan checked for you, or you had to figure out?

Thanks much!

Both : I made de calculation on my side and Titan checked for me as well.

Wow!  Let me start off by saying that is an amazing looking frame.

I have always loved the feel that soft-tail frames offer, but I did not like their long chainstays.  I looked at Dean and Funk Cycles, but their soft-tail frames have chainstays of 445mm and greater. Your frame is 427mm!  I find that 430mm is my sweet spot for chainstay length.

I have to ask, with 90mm of travel, does the tire hit the seat tube when the shock is fully compressed?

Also, did the frame come with the lower shock mount that you took pictures of?

I am seriously thinking of contacting Titan to have one of these built.  Again, awesome looking frame!

I manage to have a short 427mm chainstay because I don't need a large chainring clearance.
I ride 26T chainring. The max chainring is 28-30T. This is a MTB for the mountains :-)

Lower shock mount is included.

The wheel doesn't hit the seat tube when fully compressed.


I sewed the first bags, I need to make top tube bag + saddle bag + handlebar bag and let's go bikepacking  8)

Thanks. That mounts up better than I had thought.

Do you happen to know what the lowest amount of travel they can do with this style? I'm wondering if 30mm-ish is doable as it might play well with a Lauf fork on a gravel bike.

Very easy to mount indeed and stiff.
You can reduce the travel with short travel shock. I designed the frame around a 190x40mm.
You can design for a 170x27.5mm (sidluxe for example), it will give you around 40mm of travel.


Very nice. Looking forward to see the bike loaded for bikepacking.

Sewing has begun

It is mounted like this :










And on the upper side, I mounted an enduro bearing needle to have something as smooth as possible :

First ride : not very confident at first, then the smile arrived after the first downhill.

The bike feels amazing with climbing, perfect position, the front wheel keeps stucked on the ground, the bike is stable and easy to place in technical climbs.
While downhill : tThe downhills were 50% noseturns, 50% trial on rocks. The bike is very long and slack, it needs some time to understand when I need to start the nose turns (even flat turns). Once it is OK, the confidence comes and the smile appears  ;D

It feels like an "easy hardtail", not as smooth as a big full suspension MTB, not as stiff as a conventional hardtail. It feels like heaven to me.
I need some trial practice / manual / bunny up, to understand where is the "balance point" on this bike.









I used 80% of front and rear travel, suspension setting seems OK (no big jumps / compression on that ride)


41
Full compression : yes, when the shock air is "empty". On the trails... let's see
Sewing : yes, homemade. I have a basic Toyota Jeans. It is enough to sew VX21 packs, bivvy, poggies etc.
I don't sew thick corudra for example.

42
Final build. 11,5 kg without pedal and GPS mount, 11,7kg ready to ride.



Here is the monster  :o








Here are some details









First test ride :
not tested yet on the trails. Tested on road (1st SAG setup). The position is perfect, exactly how i calculated it.
Once suspensions locked, the bike is very responsive. Once oponed, the rear suspension is not as smooth as a "rear" full suspension bike, but not as rigid as a hardtail. It feels like an elastic hardtail  ;D

Very looking forward to test it in the mountains.
Before going bikepacking, i need to sew the packs. Something that should look like this (but with very small saddle bag)




43
I am waiting for a rear axle and nipples to mount my rear wheel... The build is standby. I will post a picture once finished and then a review once ridden 100-500km

Leon is made in Asia, in HTTC factory (I can't find any information about them).
I don't know how walty/xacd/titan/HTTC... are organised. Maybe they share (partially ?) or subcontract in same factories.

44
Ordering process :

- I sent a very complete Excel data sheet with a lot of details (full geometry, curved tubes, each bolt that i wanted, what I wanted as reinforced tubing, shock compatibility (I chose 190x40), routing of each cable, sliding dropouts, seat post, tyre clearance, max chainring size, bottom bracket, headset, disc and so on, thickness of flex plate etc. etc. With a lot of pictures to explain)

- they took 2 days to read and validate with the team that they can make it

- deposit payment

- 1 week after (or 10 days) first drawing

- I changed a few little things iteratively

- they did 4 drawings. The 4th was OK

- they build the frame, 8 weeks. They took pictures while producing

- I validated that everything seems OK and I made the final payment

- WXY tax prepaid shipping 2 weeks at home


Currently, it is quicker than ordering a complete bike to big brands  :o
I really advice to build a excel or word file with all you specifications and questions.
