Re: My TanTan TT912 build
So i had a breaking-in spin last Wed evening at a small loop in industrial zone where i live in this 90% form. its comfortable in aero position, though due to the brake lever now a lil further to reach, it took a while to get used to it. by 23km, ratling got loud. the angle-riser got loose, whole right extension was moving around. called it a day. 1st impressions: - friggin stiff.. this is my 1st ever carbon bike, n 2nd time ridden a carbon bike (1st was a rental bike in Jeju for round-island solo attempt, Gusto RCR on 23mm tires). - maybe it felt so stiff coz i havent install bar tapes. but i think i need to put some paddings at the wrist area on the curved extension. on uneven road, my wrist n watch was rocking against the hard carbon - i need to cut the saddle post more. the clamp mechanism really gave few extra cm height. - i havent weighted my bike, but its heavy. maybe coz low tier components, oh well. at least it had momentum once it got to speed - sketch in crosswind. to be expected is the tubes are so much fatter against my TCR - braking with mech disc onirii+compressionless jagwire is good. the bite is gradual. comparable to my Giant Conduct hydraulics on my tcr. not sure whats the faff that mech+disc is crap. (granted my test is in dry on flats) - sizing wise, stack n reach seemed fine, though the top tube height is a lil high for my liking ince i install the bento box. going one size down i may end with shorter reach as this frame inly have 100mm stem max Sorted both angle riser with propper torque. Now to fit my Xlab torpedo base plate, i had to extend my aero extension bar to max, and the clamp still dont sit properly. its the arm cup design as its not flat inside. Also swapped to my Chiner Pro stealth saddle temporarily as its few cm lower needs longer ride on the weekend. its really a head turner lol  March 21, 2024, 05:27:06 PM |

Re: Rd270 + carbon spokes vs DT240 + sapim cxray
Is it noticeable because of the internal width or because of the tire width itself? The 35c (25mm IW) on my gravel bike feel really comfortable compared to 28c (21mm IW) but I always though it was because of the tire width and not IW. It's the internal width that matters. The greater volume of air makes it act like a significantly wider tire. I went from a 26mm wide/19mm internal wheel to a 33.3mm wide/ 25mm internal wheel using the same tires and the difference in çomfort was clear even when running at the same pressure. Further lowering the pressure made it dramatic. March 21, 2024, 05:36:31 PM |

Re: Rd270 + carbon spokes vs DT240 + sapim cxray
the old princetons that are just like the wave rims test pretty bad in the windtunnel and the vast majority of wheel stiffness comes from the spokes, the rim doesn't affect it much except fot a deeper rim meaning a wider bracing angle for the spokes

Re: My TanTan TT912 build
I still need to revisit the Versa BTA plate. its rocking against the arm cup, making annoying noises. i will probably swapped the armcup to the ones on my Controltech aerobar kit on my TCR(currently the bolt is siezed). swapped to my old tcr giant approach saddle, since its lower stack. i may be in market for a short-nose saddle as my aliEx Pro Stealth saddle base getting soft n saggy btw, this frameset used Sram UDH style hanger. I finally got the bike completed, minus the temp crankset  im a lil afraid to do bike photoshoot since its like a flag/sail, can topple at anytime when theres wind  Frame: TanTan TT912 size52 + IceCrack blue paintjob Stem: TanTan alu stem 100mm Basebar: TanTan HB096 400mm Aero extension: TanTan HB086 44° + 80mm w/ 15° angled riser Brake lever: Tektro TL720 Saddle: Giant Approach (from tcr) Crankset: 105R7000 170mm (from tcr) Chainring: 50/34T (from tcr) PM: xcadey xpower2 left crank 170mm (from tcr) BB: ztto bb386-24 normal bearing Shifter: Microshift BS-A11 RD: 105R7000 SS Cassette: 105R7000 11-28 Wheelset: Parcours Chrono 77/86 Rotors: 140mm MT-RT900 Caliper: Onirii BR005 mechanical Looks awesome, well done!Currently im still on 28mm gp5k front n back. once the rear worn out, definately gonna fit in 32mm. the cockpit felt a lil better now with the bartapes. Since i already have the frame, folks can just AMA  Really great to see updates on this, the price of TT bikes at the moment is painful. I would love to know the actual weight of this and if you manage to sort the rattling / things getting loosein SG even 2nd hand tri bike market going at silly price for the age of the bike. my build(minus parcours wheelset) literally can get almost 2 new speedmax cf7 105 mech. the headset rattling issue was sorted with the micro spacers that i forgot. tomorrow i'll weight the bike edit: it weights 10.3kg equipped as in pic. bta not yet attached. heavy AF. i did considered a lightweight build ala Sebastian Kienle Norseman Tri scott foil tt-cockpit, but decided to go proper tri frame geo March 23, 2024, 11:21:42 AM |

Re: TanTan TT-X21 frame
Hi everyone, I'm refreshing this topic to show you my future bike! This is my first experience with TanTan and I'm very satisfied with the service so far. I had very specific requirements for this turnkey bike, and Rose from TanTan was very helpful. Here are the photos I received today. Description : TT-X21 custom paint Size 56 50mm carbon rims with Continental GP500 Shimano 105 Di2 They should ship it this week, I can't wait to receive it. I will update as soon.

Re: VeloBuild VB-R-268 frame
1. You plan to route 4 housings through the bars & stem using this https://jagwire.com/products/diy-cable-kits/2017road-elite-link-brake-kit? Having routed 4 VB bikes with keb-sl housing (full internal), i really dont think it's possible, so very curious to see how you manage that. My built is finally finished. At the end I opted for only twoo of largest spcers, one from my extra spacer kit (I know, its the same hight, but less hassle). When I tried to assemble the handlebar with the 4 cables I quickly gave up the idea of using my used link cables. The thight space in the handlebar lead to gaps between the links, so I ripped it out and used the jagwire road kits instead. I don't like how velobuild routed the cables underneath the stem. They dont run internally, inside the stem, but underneath of it in a canal. So there is a even tighter bend between the fork and the handlebar. I even had dificulties running the inner cables through the housing when reaching the bend. They got stuck, and I had to loosen the handlebar again. It would have been better if the cables run inside the stem. They would have more space for the a bend with a biger radius. It was a big hassle, but at the end everything is working well. 7,8 kg with Sensah Empire pro, onirii/iiipro cable/hydro disc brakes and elite edge wheels. March 30, 2024, 03:04:56 PM |

Re: VeloBuild VB-R-268 frame
My first look video is live on the channel. Thnx Pat! Not a great fan of the color, but really looking forward to your build, especially regarding the routing of the cables around the headtube/fork. April 02, 2024, 08:23:49 AM |

Re: VeloBuild VB-R-268 frame
My first look video is live on the channel. As someone who currently runs a 140 stem on his setup and wants to see that fsa 69 headset on this frame, get to work! i need to see if it looks good or not

Be careful when you see trucks, you can get pushed or sucked in hard on something like that, try not to die.
