Thank you for the pictures!
Titanium is so beautiful :D

I didn't know you could choose the welding type.

You're welcome.
Not the welding type per se but rather filing the weld smooth.

tripleDot ,

Man that is pretty, you must be excited. I came close to buying a Lynskey Cooper CX frame fora good price on eBay about three weeks ago. The only reason I didn't is because it wasn't what I REALLY wanted. The problem is that nobody made what I really wanted. I'm glad I found your post, now I can design what I want for a great price ...I'm looking forward to it. The price you paid for your frame is very close to what the Lynskey would have cost me.

A couple of more questions
1) Do you know if butted tubing is available
2) What type of bottom bracket is that?
3) If you have it available can you tell me what the frame specs are, geometry and tubing size? That would give me a reference for a design starting point as well as visually.

Once again, great looking frame.

FTH

FTH, I can relate to your dilemma of finding a branded Ti frame at a very nice price only to realize it's not what you wanted. There's always the feeling of I don't want to be stuck with or without that features I need or want.

1. I did asked Peter about butted frames but he didn't answer and I didn't press the issue. Although I have read a few guys saying that this manufacturer don't do butting. Still, these guys did not have any problems with their frames so I didn't pursue it.

2. I had my bb threaded for Shimano cranks, I believe it's BSA. But you can have it in other standard, even one of those Press Fits.

3. I copied the geometry of Jamis Renegade Exploit size 54. You can download it's geo sheet from the Jamis website. I initially wanted to copy the Niner RLT (geo sheet Niner) but they're very similar to the Exploit and I've ridden the Exploit's aluminum brother (Exile), loved it, and went with Exploit. You can really just check out most any of the popular brands, they have geo sheets of their bikes open for scrutiny & download. As for tube size, l measured a friend's Salsa Ti Colossal. I'll try to find my email to Peter regarding the tube sizes. But you can have Peter take care of tube size.

Bike components:

Frame: Custom Ti gravel - Carbon Speed
Fork: Carbon Speed cf Gravel fork (disc)
Group set: Shimano XT 1x11
Chainring: Stone 42T narrow-wide
Wheelset: Stan's ZTR Crest MK3 29er rims,
    DT Swiss 350 classic hubs thru-axle,
    Pillar spokes & nipples
Tires: Continental CycloXKing 700x35c
Headset: Token Problem Solver,
    Control Tech compression plug
Stem: On-One 70mm Hot Box
Handle Bar: Crank Brothers Cobalt 3 600mm
Pedals: Crank Brothers Candy 2 (silver)
Saddle: Brooks Cambium C17 All-Wheather
Seat Post: Carbon Speed cf
Seat Clamp: Six Pack
Bottle Cages: Carbon Speed cf
Grips: WTB Padloc

Total weight: 9.6kg
Estimated cost: around US$1,900.00

Very happy with it, although I still have a couple of problems that needed to be fixed. First, I got a post-mount fork and XT brakes (flat mount I believe)... I need to get an adaptor as I completely missed this one. Second, my rear tire's tubeless set up is leaking air. Will have to check it again.

Very happy because the chainring clearance for single ring was quite big. I believe that l can fit a 48T round or a 46T oval ring. The total weight was a very pleasant surprise. My initial estimate was around 12kg but it came shy of 10kg. And it feels light when pedaling, l did a short 5km ride on it.

Full ride review would have to wait though.

tripleDot,

Awesome bike. Do you recall what that fork weighs or what the max tire clearance on it is?

Sadly my attempts to reach Peter at CS (three or four emails to two different email addresses as well a Facebook Messenger) the last few weeks have met with no reply. It sucks because I'm looking at two project and I need two frames as well as rims and other parts.

Thanks FTM.
Unfortunately, l was not able to weigh the fork but it was very light. It is an FK-029, the companion fork of CS GR-029 Gravel frame. As per Carbon Speed listing the max tire is 700x40c. I also shoot Peter a PM regarding you trying to reach him.

Finally got it out on a full ride. Joined the Audax Rizal 200km, considered to be the hardest brevet in the Philippines. It's a climb-infested route. I didn't finish, didn't make the last checkpoint cutoff time. Overall, I rode some 180km. With 20km to go and pretty much 12km of climbs, the setting sun and an hour to cutoff time, I decide to throw in the towel. It was a fun ride, very nice weather and lots of scenic views, so not finishing wasn't that big of a deal.

It was a sweet ride. The frame felt good. Not much to say about speeding on flats as the route were mostly climbs and descends. Double the pain but double the fun. The bike is confidence inspiring during descends. I personally usually hold back on my descends as I'm not the most skilled in this department (usually just doing under 40kph) but was hitting 50's on this bike. Went thru a section of unfinished road (lots of rocks) at 35kph and still felt confident doing it. The roadies behind me were just amazed with what I did. 35c tires doing that. There were also a few sections of the road that felt rough on descends but the titanium does absords the vibration pretty nice. At the end of the day, it didn't felt too harsh on the body.

Assessing on why l didn't finish, l came to the conclusion that I should have used my old 38T chainring instead of the untested new 42T. I could've climb faster, not much flat for the 42T to shine. Also did a quick examination on the frame to check for visible cracks or damages, everything checks out well. Bottom line, I love this bike.

A couple of pics from Audax Rizal.
Last pic also in Rizal but not part of Audax.

Thanks for the report !
Do you feel a big difference compared to riding a carbon frame ?

@Carbonazza, if you mean by difference in the material absorbing vibrations, a.k.a. harshness of the ride. It is kind'a hard to explain. It's hardly noticeable, at least for me. The only way I know how to compare it was after doing 150km on a cf road bike and 200km on a cf plus bike (both mostly flat), l pretty much went to bed tired. For this ride, I was still able to spent an hour on dinner and a bottle of beer. Spend another hour on checking my friends' ride status on Facebook before hitting the sack at 9pm. And surprisingly, I was awake next morning at 5 and feeling good. I thought I'd sleep past 8 or 9 after that ride. And then I took another 60km ride (3rd pic above). For the record, I rode 60km on Friday, did 180km on Saturday and another 60km on Sunday.

I guess it's not felt so much while riding but you just feel better after the ride.

tripleDot,

Hey man, I hope you're still enjoying that ride. I'm still trying to figure out what I want exactly. I know your design was heavily influenced by the Jamis Renegade Exploit. I'm trying to start a spreadsheet for bikes with geometry similar to what I'd like. Previously you mentioned that you might have a reference to the tube sizes you spec'd. Do you still have that info anywhere?

Thanks,
FTM

Hi FTM,

Here's the tube diameters I used. These figures are actually based on a friend's Salsa Colossal Ti (size 58), I took a Vernier caliper and measured it myself.

Tube diameters:
Top tubes: 35mm
Seat tube: 32mm
Bottom tube: 40mm
Seat stay: 16mm
Chain stay: 16mm x 27mm (oval)
Head tube: 44mm
BB tube: 46mm

You can also let Peter and his team take care of the tube sizing.

tripleDot,

Awesome, thanks for the info. I take it you're running a 30.9 seatpost?

@FTM, I'm running 27.2mm seat post. The 32mm seat tube is outer diameter.
