Another Budget TT/Triathlon Bike Build
« on: March 29, 2025, 09:15:40 AM »
Hi Chinatown, new here. this is just going to be my build thread for hopefully my new Triathlon bike.

With TT frames very limited on Ali I'll be going with the very popular Seraph TT912, hopefully LT-WOO release the er9 TT shifters before the end of the year or I might have to rethink groupset options. Haven't decided on all specs on the set up but that'll all be shared here eventually.

For the time being here are some wheels I build which has started me on this budget bike build!

Goldix hubs 21 spoke 2:1 (not g£  :-\) -£82.79
Ridelove Carbon 88&60mm 21 G3       -£221.94
Pillar bladed spokes + brass nipples     -£46.33
Rim tape -£1.87      TOTAL BUILD SUB £350!!! Love it

hey tt912 gang.
hope your build go smooth. 

i just saw ollie testing the ETX with ER9 tt brake-lever that actually has buttons on it. so theres potential that the aeroExtension bar shifter also wireless.
my tt912 is with franken sram axs setup

The L-TWOO TT groupset is available from Canada Yoeleo.  The current one has shifting from the aero bars, but not the brake lever.  I am hoping that it will work with both.  Hopefully they will release it officially soon.  I don't know why the only place (including L-TWOO website) that I can see anything about
this groupset is on the Yoeleo site!

Yes I had noticed, but I'd really like buttons on levers and bar ends. I am umming & ahhing about 3D printing bar end buttons and mod'ing a standard ER9 groupset with Riderever Trivia brakes. how hard could it be to transfer the electronics to a different housing?? Or do I be patient and wait for the ones just reviewed in Taipei?

As an electronics guy, I'd love to see somebody try to dig in and do that.

Would it be doable? I'm not an 'electronics guy' per se but I do like a good tinker. hence building the wheels myself.

My assumption is I can just wire in a second button cable to the the existing wire connections?? and hopefully the electronics part of the shifter is small enough to rehouse in a 3D printed bar end shifter with the new cables going to the levers on the base bar. Well that's the theory..
