Jeesh.. All of this bottom bracket talk has me feeling like I made the wrong decision. My 54cm will be here sometime next week.

Question, have you been using the supplied thru axle or an after market one?  Also, I don't think that you have to worry about "No longer recommending the Seraph/TT-X68" as from what I understand they are no longer selling that frameset.  Folks inquiring about buying one have been told that they (TanTan) have sold the molds, have no more framesets in stock, and are only selling the remaining stock of complete X68 bikes.

I was told yesterday that they have 44, 52, 56 and 58cm frames left in stock and are selling them offline.

Can anyone here confirm that the chainstay thickness is the same as the SL8 (I believe 25mm?) at the rear caliper mount? Trying to make sure I have the right length Shimano bolt before the frame arrives.

So what's the latest with these frames - any improvements made quality wise?

I am currently riding a nice steel allroad bike (for comfort) and an older aeroframe (for speed) but I am looking to replace the aero bike with something a bit more allround.

The aero bike is amazing when going really fast, but most of my riding is done solo on rolling terrain with no long steep climbs (except the occasional trip somewhere with real mountains).

For comfort, I will keep my steel bike, but I would like something:

- lighter than the aero frame (which probably sits around 1300 g for the fram painted size 56
- doesn't need to have monster clearance, I don't see myself going above 32C width since I have the other bike for that
- still should have some aero credentials
- slightly more forgiving than the aero bike but again for max comfort I ride my steel bike
- still racey geometry

Basically a Cannondale SuperSix Evo but without the price tag

Considering the X68, but somehwat put off reading about fork breaking, BB delaminating .etc.....

Also eyeing the new LightCarbon LCR020 / TanTan TTX-67 but I guess those would be really similar to my current aero bike....Looked att the LCR017 but put off by the boxy downtube / not very aero looking tubes.
Yishun R033D looks pretty sweet too, but not sure if they do 1 pc sale to retail customers.

Any other frams to consider?

I can offer the other frames I was eyeing as they were somewhat similar in geometry to the SL8/X68:

-SPcycle R088
-Velobuild 268
-Ican A9
-Lightcarbon LCR018 (one size down)

About to pull the trigger one of these X68 frames and had some questions..

-Is it worth shopping around on AliExpress for an upgraded handle bar, such as ones that are compatible with SL8's? Just how flexy are these stock bars? Has anyone tried a different integrated cockpit with success? Worth it to shop outside of AliExpress?

-Recommend upgrading steerer plug or are folks having good luck with the one supplied?

-Out of precaution, any tools or methods to help clear excess carbon out of the seat tube for Di2 battery?

-Should I just book a time at my LBS to have the brake mounts faced or can it reasonably be done yourself with a file and some elbow grease?

Feel free to recommend any other parts or supplies for the build.

How optimistic is it to expect it's arrival to the states by end of July if ordered tomorrow? (6/12)

Would Chinese (Ltwoo, Sensah, Wheeltop, etc..) 11spd mechanical hydraulic shifters be compatible with 11spd SRAM mechanical derailleur's? Looking to use my 11spd Rival rear and Force front derailleur's on a new BXT 135 build. My current shifters are Rival mechanical rim brake.

I'm also interested in aftermarket integrated bar options in order to reduce flex. Or do we feel it's more related to steerer/headset/compression plug area?

If memory serves me correctly I think Pat Lino did this with his and mentioned it in a past video?

If you didn't fully commit to the X68, you could take the R088 from Sp-Cycle, basically the X68/SL8 geometry without the aero sniffer.

Sp-Cycle has a gravel frame that is inspired by Canyons Grail, the G068/69. That would be my way of going in your situation, if I wanted to save on the shipping.

Disclaimer: I ride a X68 and a G069

Thanks. I saw your posts on the long X68 thread. 90 days, right? How would you compare the quality and experience of Sp-cycle to TT/Seraph?

Anyone know if TT/Seraph offers a frameset that is geometrically the same as a western known branded frame? A Diverge or Crux clone would be ideal but open to others.. Checkpoint, Checkmate, Grail, Grizl, etc..

Reason for a clone: Comfort/fit. I can get fit locally for said frame set and then build up a chiner frame based on those measurements. I ride a 54cm, but have no idea on stem, reach, cranks, etc.. I plan to go integrated cockpit and know you only get one shot. Comfort is super important to me.

Reason for TT/Seraph: Shipment savings. I plan to also purchase and build up their X68 frame set. If I can save on shipping by buying both at the same time, that's likely the route I'll go.

Edit: I have played around with BikeInsights and compared different frames and geometries but am having a hard time finding a match for their gravel frames.
