Re: VeloBuild VB-TT-023
Hi! Here’s another build. Put it together last autumn and didn’t have any major issues, apart from Velobuild never sending me a replacement for the incorrectly painted bottle mount even though they promised they would… Build was relatively easy, after I gave up trying to make Juin Tech F1 brakes work and switched to Riderever Triva ones. It’s my first tri-bike, so I have nothing to compare it to. Fun to ride, and certainly fast enough to make me the bottleneck, not the bike ![]() However, the seat post has recently started slipping when under load during a ride. I first noticed it after going over an extended patch of grooved asphalt - pure washboard. I wonder if that might have damaged something, but I can’t see any signs of that. What’s the maximum torque for the seatpost wedge? Are there any good tricks to secure the seat post better? Thanks, Markus June 23, 2026, 12:20:45 AM |

Re: VeloBuild VB-TT-023
Looks like Sunpeed is now selling complete VB-TT023 as 'Sunpeed Interstellar' limited info on pricing but some sites list it for around 11k USD :O

Re: VeloBuild VB-TT-023
Here’s a photo of the build as of today I got the wrong bb originally, got the right one a SRAM T47 Inboard, also the ZRACE rotors where sketchy, so I got SRAM Paceline. I also got the LEAP components sram aero handle. Thinkering on the hydration system since I’m using this bike for Ironman training/racing. Hi everyone, and thank you for all your contributions. I recently placed an order with VeloBuild for a TT-023, went with the custom paint job; I have to confess, I took some of the images in this thread and applied the paint job with ChatGPT; See below, I'll continue to post a real photo once I receive the frame and starit the build-out. Build details below, so far I've spend around $3,650 USD. Also have a Elite Wheels rear disc wheel in the cart for $475 USD but not sure to pull the trigger. July 24, 2026, 11:17:40 PM |

Re: VeloBuild VB-TT-023
I also finally managed to build my Velobuild TT-023. Attached a photo of the finished bike. Here is my setup: Frame: VB-TT-023, 1022 euro Bottom bracket: Senicx ceramic t47 bb, 44 euro Wheels: Elitewheels 80mm, 370 euro Tires: Vittoria Corsa Pro G2 TLR with TPU Ridenow innertube, 101 euro Rotors: RT-CL900 dura-ace, 45 euro Groupset: shimano Ultegra/dura ace di2 12 speed for tt bike, 1004 euro Chain: SUMC oil slick 12s, 48 euro Cassette: ztto 12 speed oil slick, 26 euro Powermeter: Stages R8100 170mm, 231 euro Saddle: Pro stealth aero 132mm carbon, 90 euro Bottle and cage: Elite Crono CX, 31 euro Pedals: Ultegra R8100, 48 euro Garmin mount: Closethegap raceday evo fi, 60 euro Tools: misscelanious, 46 euro Total: 3166 euro The installation process was quite easy. Most exciting part was cutting of the fork (measure ten times, cut once). The cable routing was very easy. The only downside I have noticed so far has to do with the cassette. The Ztto cassette doesn't shift as beautiful as an ultegra cassette. July 30, 2026, 03:32:20 AM |

Re: VeloBuild VB-TT-023
Hey folks! I finally built my TT-023, thanks in large part to this amazing thread. I’m based in China, so I sourced everything locally and mostly Chinese-made, including WheelTop’s latest TT groupset. So far, it seems to be a pretty good deal. I had my local bike shop handle the build, and the mechanic didn’t run into many issues. The only problem was that the seatpost kept slipping until I tightened it to 8 Nm, as recommended by Velobuild’s after-sales support. I’ve only ridden it outdoors once because I mostly train on a smart trainer and the weather hasn’t been great. That one ride was awesome, though—the bike feels comfortable and stiff, and the data suggests it’s faster than my road bike with clip-on aero bars. Duh, of course! I’ll be racing it in a long-course event at the end of this month. If anyone’s interested, I’ll hopefully report back afterward. Below is my setup: Component Brand / Model Price (converted to USD) Frameset VB TT 023 $932.03 Groupset Wheeltop $577.83 Crankset 105, 165 mm $78.55 Chain DA $35.57 Cassette UT, 11–30T $38.24 Bottom Bracket Token $38.68 Wheelset Exar DB607 Ultra(used) $370.50 Brake Rotors iiipro $15.41 Tires Power Cup $91.88 Tubeless Valves & Sealant Boostor & Giant $14.38 Bar Tape Boostor $9.04 Saddle Baluego(used) $41.35 Bike Assembly — $207.48 Total $2,450.93 August 07, 2026, 02:05:25 AM |

Re: VeloBuild VB-TT-023
Love the bikes name. I customised the decal sticker after ordering the frame in stock glossy black. The colour I believe to be chrome silver. It's much cheaper to do so (around 8USD) and I can regret anytime if I feel stupid about the name later on. August 11, 2026, 01:49:26 AM |

Re: VeloBuild VB-TT-023
Hey folks! I finally built my TT-023, thanks in large part to this amazing thread. Hi there, your build looks spectacular!! I wanted to ask where you got the BTA (Between The Arms) setup for the water bottles and the Garmin mount. Could you tell me where you bought it or if it’s a 3D-printed part? I’d love to get one for mine. August 19, 2026, 07:13:02 AM |

Re: VeloBuild VB-TT-023
Thought I'd create a database of sizing information so anyone who's looking for data to determine their size doesn't have to scroll through every page looking for peoples stats! Anyone can add to it, so feel free to enter your info and add to what I already entered! https://docs.google.com/spreadsheets/d/1aNIhC5_5a3Dju2BEAoBR9Kvwz5ZMp87Sg0r91vQ2qaE/edit?usp=sharing August 21, 2026, 08:08:50 AM |

Re: VeloBuild VB-TT-023
Hi all, I´ve never seen this problem. Do the bearing and the crawn fit well outside the fork, just to see if they match? Looks like diameter´s bearing is a bit small. Did you write Chris about this? August 25, 2026, 02:06:12 PM |

Re: VeloBuild VB-TT-023
Yes I sent Chris a few messages. He said push harder but not possible. Have a look at the photos attached. "Push harder" Unbelievable! There is a pic of my bike, you can see that it is completely flat in the fork. So Chris or whoever sent you the wrong crown has to take responsibility P.D: We've been having problems with the headset and the stem since we built our bikes. We ordered new aluminuim stems and Chris didn´t sent us the new washer needed. And if you read this post, you can see that simmilar issues are recurrent. What annoys me the most is that this frame has been in the market for a few years and they never bother to solve desing issues. Same happened to other frames from Velobuild. I don´t think I could recommend this brand to anyone I know. August 27, 2026, 02:34:20 PM |
