That's around the time they were purchased but supply issues elsewhere meant a change of direction. I don't see why they wouldn't be interchangeable with a gravel or MTB set up. The hoses are pretty much the same. 

Looking for 100 mm stem and 38 cm carbon aero bar and stem for Speeder SC 48D. Speeder do not have stock. 
What is light weight, available and will look appropriate on the Speeder frame. Happy to consider integrated or separate and something that has a proven history (ie not a no name brand or copy). What's out there?

Ok, here the comparison on Geometry Geeks https://geometrygeeks.bike/compare/tantan-tt-x33-2022-54,tantan-tt-x33-2022-56,pinarello-fp3-2009-540/

Then you measured the Reach at 386, you are closer to a 54 than a 56 for the TT33. Only the Head Tube and the stack are lower so I would think it is a more aggressive position. If you take a 56 you may have to take a shorter Cockpit (but I would not go below 90) and maybe you can put the saddle slightly forward but you may be quite stretched... Your fitter should be able to give you a sound advice.

Thank you so much for that. I'll look into it in detail shortly.

Which model was it?

2009 FP3 in 54cm looks to be the frame.

I have narrowed my search down to potentially the TT X-33. Looks like a decent balance of modern geometry, T1000 carbon and price.

I am looking for guidance on sizing between the 540 and 560. 

Currently riding a 10yr old Carbon Pinarello and have  been fitted by a professional bike fitter.

I have measured the current frame and am confident these dimensions are accurate within a few mm.

Current bike:
Reach 386
TT length horizontal 560
Stack 563
Wheelbase 991
Chainstay length 410
Front centre 595
BB drop 80
BB height 265
Head tube length 160



Currently using 100 mm stem no spacers and 420 wide bars.

Would like to go to narrower bars.

Comments on sizing please.

I  am going to build a 27.5 hardtail for my wife. Looking for comments on the latest frames with modern geo. Boost not really needed. What's out there ATM?

Any thoughts on running the Fox Suspension 32 Float Performance Boost Fork, only 100 mm travel is my concern but nice and light?

Edit : went for a 140 mm fork.

Excellent thank you for the link. Got it now
