Hey all, I’m piecing together the parts for my first ever TT bike - I’ve done so much research (thanks to this forum) but still not 100% sure of compatibility and whether or not I’m getting the most bang for my buck?

Appreciate any advice on the below build.
Total Price $4,644 (AUD).
Use case will primarily be for local sprints/olympics and 70.3s and the rare (maybe 1 every couple of years 140.6s)

Keen to know:

    Any compatibility issues or just poor decisions
    Any easy/cheap upgrades or downgrades (note, I want SRAM wireless shifting so pretty set on that)
    Missing any FUNDAMENTAL components


Once I buy everything, plan is to have it professionally assembled by a shop who offer full build (hopefully they’ll let me watch - i’d love to learn, and im not comfortable doing things like brake installations, bleeding, cable cutting etc.)

All prices are AUD.

Looks good and I dont see any compatibility issues. I'm using the Ryet Saddle on my road bike, but I'm not sure if I'd go with it for a TT position.

I will also print @mattgolt rear bottle holder and toolbox (if it fits  size S frame).

It doesn't fit size S, sorry. I haven't had time to design a parametric version yet 

I did my own "pad" using a mold of my arms (used plaster for the mold)

Dude, that is another world of DIYing  I'd love to do this with my cockpit one day, given that I'm almost there with an optimized geometry and I would only need to print a mould and then layer the carbon. Do you have more documentation about your process? Especially what carbon/resin you used, layering directions, thickness, strength testing?

The tt extensions have the same aero design problems as the rest of the frame, you're better off with the winow ones

That was exactly my intention in posting this. Winow stops at size "L" 

I don't think a bento box would fit nicely on this frame, because the headset is recessed so the basebar sits flat with the frame, which I very much prefer. This is one of the reasons why I chose this frame over the winow T119 frame.

However, my dream is still to find a cockpit with a monoriser, and then put a bottle/bento box behind it. That's why I had velobuild put in two threads on the top tube, but I haven't used them yet.

Yeah about cutting a hole in the frame for a bladder.... Idk if I would be brave enough riding that 😁 But if you want to go down that route, fyi: canyon does sell the bladder for the speedmax separately including the filling valve, and they're not even that expensive

Have you read the post or only the title ?

Surely this will motivate people to help you 

Hi Guys,

I am thinking about buying the VB-TT-023 frame, but I want to know how far the seatpost can be extended?
The description on their Homepage say, 400mm length. But is it the whole length of the seatpost or is it the length which I can extend?

Thanks for your answers 😉

The total length of the seatpost is approx 400mm. But judging from the grip-paint on the seatpost, you should keep minimum ~120mm of the seatpost in the frame. I currently have ~170mm of seatpost in the frame, so I could actually raise the seat by another ~50mm. All made up numbers btw - I didnt find any information from VB.

On the frame L, my setup gives me 83cm from saddle to bottom bracket. I'm 188cm with 92cm inseam.

If you are really tall, this frame would probably be too short before you run into seatpost issues 

Yo yo yo, 3d printable rear bottle holder is finished! It replaces the one that comes with the frame, but elevates the bottle higher and mounts it horizontal. I suggest using a bottle mount adapter for fine tuning the fore/aft of the bottle, but it could be mounted directly. (Depending on the bottle cage, you might touch the bottle though)

It is compliant with the current ironman/world triathlon rules about the mount for the rear hydration having to fit in a 30x30cm box.
