Road Bike Frames, Wheels & Components / Re: VeloBuild VB-TT-023
« on: March 23, 2025, 01:30:37 PM »
I've received a PM about the toolbox I have designed 3d printed for the VB-TT-023. If anyone wants the .stl file to print it yourself, feel free to download in on thingiverse:

https://www.thingiverse.com/thing:6988838

I suggest using PETG for this box, as it offers flexibility aswell as heat stability and UV resistance. Both pieces can be printed without support if you flip them to the flat side in your slicer. You'll need two M5 screws to attach it to the frame. Sadly using this toolbox, you will not be able to mount bottlecages in the frame correctly any more. I haven't found a way yet to circumvent this, but if I do I'll post a new revision.

That would be awesome, i am searching for it.

I just measured with a caliper. The outer diameter of the basebar is 23,8mm.

Inner diameter of the leap grips is 24,1mm. I used one layer of electrical tape to adjust and make them hold correctly

Love the paintjob and the cockpit looks super slick. Have you done something to increase the reach? Those bars look alot further forward than they did with the standard VB plate that the extension towers bolt in to.

Yest, reach extension has probably been the topic that held me up the most while finalising the build.

Hate to be that guy, but please spend 90$ for your safety  ;D. I had a mock up setup made with aluminium extrusion for bike fitting purposes during winter on my hometrainer. Once I found my position I spent 90€ on these extensions, as they increase wingspan and reach at the same time:

nice!

Which Leap S900 Grip Shifter is it, 24 or 25?
Thanks! I wasn't aware there were different sizes. I can measure it for you, but will take until the weekend is over.

Nice tool Box, where did you get it from?
Self designed and 3d printed. :) it's still undergoing a revision since I cannot mount a bottle in the frame any more. But afterwards I'm happy to share the .stl file if you want

Doneeee. Took longer than expected as I fiddled a lot with the cockpit. Very happy overall but the list of wanted/unnecessary updates is long

All parts have finally arrived and got the rig set up.

This is so hot. Love the ghetto bottle rig. I've designed a plate that let's me mount it in a similar way. Currently only 3d printed, but I'm looking to have it lasercut somewhere.

What size of the winowsport extensions do you have? And how tall are you? They look nice and long. I'm having some trouble with the original ones from the vb-tt-023 since my arms are quite long

7
What material are you printing them in? I would v.concerned if plastic or similar given that these go in the riser stack. You can pick spare spacers on AliEx for a few quid.

The important bit is to never rely on the strength of a printed part. The spacer I shared has two m5 bolts going all the way through it, so the plastic will always be in compression. The printed part can only break if one of the two m5 bolts breaks, too. And if that happens, I have a different kind of problem.

I'm using PETG

8
I will design and 3d print if I need to increase stack height.


You can use my file if you want to. I've used printed ones aswell without issues, to find my correct height. Once I'm done with fitting, I'll replace them though..

I only made 30mm versions, but you can strech them in your slicer obviously.

Finally finished my VB-TT build. Only ridden on Turbo so far so no idea on road feel / secureness of contact points (particularly concerned about Bars / Seatpost slipping on bumpy terrain)

Components:

SRAM Force Rear Mech
2 pairs of SRAM AXS Wireles Blips
76 Projects Blip Holders
RideRever Trivia TT Brakes
Stock Basebar and Vision TFE Clone Bars
Pass Quest 56t Single Chainring
Dura Ace R9200 167.5 mm Crankset
KMC 12 Speed Chain
Praxis T47 Integrated Bottom Bracket (Shimano)
Shimano 105 R7100 11-34t Cassette
ISM PN3.1 Saddle
*I do have a SRAM Red eTap AXS Front Mech and Pass Quest 56/42t Double Chainring for a 2x setup
Tri Spoke and Disc to be obtained in due course.

Cost: £1,921.54 (not including labor to build or 2x Chainset setup)

Love it! Didn't know you could mix and match Shimano and sram like that, but apparently you never stop learning!

I'm due to receive my frame soon aswell and plan to go for a 1x setup as well (living in pancake flat northern Germany..). So I'm wondering what offset did you chose on there passquest chainring? Did you spend lots of time to optimize the chain line?

Just ordered a VB-TT-023 in white ice crack, with the extra threads for a bento box on top. Hope it will turn out alright! Gotta keep busy in the off season  ;)

Picture from ironman event

Finished the build just in time I guess! Hope you are happy with your bike split. I'm doing a 70.3 next weekend on my road bike and if I like it, I'll build a tt over the off season and do a full IM next season. Nice picture, and nice fit btw! Care to share your height and frame size?

I also asked them to add some bento box rivets to the top tube which they said yes to, so that's an option.

You're getting me all excited! ! Not sure if I can handle this on a Saturday morning

Please post pictures once you get the frame

Superb build and sooo clean! Love seeing tt builds on this forum more and more. I'm also thinking about building a tt bike during next winter, and I'm thinking the tantan tt912 or velobuild vb-r-023. I'd be super grateful if you post more pictures. Especially details on the mounting points. Can the frame hold a bento box? Or does it have other storage means for nutrition? Alsooo, can you mount a front hydration system to the stem? Sorry for the spam, I'm just getting a bit excited for this frame

Hellooo fellow triathletes!

I wouldn't have thought that my sketchy TT setup actually does draw attention, but this is a forum of people riding sketchy frames from (partly) unknown sources, so theres that.

Let me share my journey for you guys, I can also share the 3d print files as .stl or solidworks-file if anyone wants them. Short disclaimer regarding 3d printing: Please, for the love of god, only use 3d printed parts on bikes if you absolutely know what you are doing. 3d printed parts are not rigid enough  to be used in any tensile stress - especially because the layer lines can break apart easily. If you pay close attention to the 3d printed parts that I use, you'll see that all of them are used in compression only.

- After lots of resarch I did not find any dogma fitting aero connectors, so I purchased the giant propel aero connectors (GTIN: 4713250834511). Hoping they would somehow fit. They did not fit, and clamping them down like this would have definitely damaged the handlebars (see first picture).
- I have then 3d printed banana-shaped adapters from a soft-ish rubber material (TPU, for those who are familiar with 3d printing materials), to adapt the giant-shape to the handlebar of the VB218. This has worked out okay-ish (see 2nd + 3rd picture) but the armpads were too wide apart and too far forward.
- In the first ride on my hometrainer, I have noticed, that these rubber bananas create side-to side flexibility.
- I have then had a local shop cnc mill an aluminium plate (see 4th picture) to solve two things: a) side to side flexibility and b) give me more options of placement, especially fore/aft, and distance between the armpads. This has worked execptionally well, as it gives enough variability in position, but also is super stable without clamping down too hard on the handlebars.

What I also did to improve the TT fit on this bike:
- get an ISM PN1.0 saddle (move wayy forward)
- get a 0° setback seatpost

Still on my list to do:
- get a between the arms bottle
- print a rear box, similar to what the guys at 4-frames do. First protoype is done already (see 5th picture)
- ride more
- get a TT frame (project for next winter  ;) )

I've been contemplating getting these to try on 218 bars.

Hi JonMS, these might actually fit - but I suppose you'll also need some kind of rubber adapters.

Are we doing update posts? 3000k update from me! Still working like a charm. I have put some "skateboard" grip tape on the seatpost wedge, as it wanted to reduce the torque on these bolts after what I've seen in this thread. Seatpost now holds with 2nm on the bolts.

And I can confirm you can actually ride TT on this, if you are brave enough and have a 3d printer, lol. A bit sketchy, but I wanted to try out the TT position for a bit before I pull the trigger on a new frame
