Trends change all the time, but the laws of physics don`t. Fast bikes are still fast bikes - just like this vintage Shiv TT. We have made some serious upgrades to it to get it more in line with the competition and ended up with a really potent machine. Here is how you can do it too.

Wish your customer the best of luck for the Masters TT Worlds next year. The bike is looking good, some frames are just timeless (& some riders too). Thanks for sharing Roni 👍

Thanks 🙏

Great video, very informative as usual. Very good point about longer cranks are more aero. There is common opinion the opposite is true, but it does not hold water under scrutiny. Keep up good work.

[@ronykuba]

Thank you! Yes, that’s another good example of people taking facts out of context. Similar to “lower tire pressure is faster”.

I raced the pan American masters games this year, it was where I live on my home roads. It’s the only TT I’ve ever done. Nobody was checking bikes, and I was slightly out of range. If he’s racing the world masters games in Taipei next year, I would not expect a measurement. I got 3rd in 35-39, and in out young age everyone who competed lived in the area.

He’s aiming for the UCI GF masters champs, they’re pretty strict there

Great video! Nice setup, cool to see Tririg stuff being put to use.

[@ronykuba]

Thanks 🙏

[@treyxt]

great video!

[@ronykuba]

Glad you like it!

Awesome bike! I am a bit confused about your choice of tires. Corsa Pro does have a tubular version, is there a reason you went with the older Corsa Speed G2? Is the newer Corsa pro tubs slower? Also what tire width did you choose? These older FFWD wheels have relatively narrow rim width, so I'm guessing you went with 23mm tubs?

[@ronykuba]

As I said in the video, there’s no Corsa Pro Speed tubular, so the Speed G2 remains the best option. As 23mms are also no longer available, we went for 25s.

How do you move the junction box in the frame? I have the same shiv and my shop left the junction a box in that position on the base bar

[@ronykuba]

By making some modifications to the frame.

Are TUFOs slow in general, or just the TT ones ? (just bought a bike with TUFO Comtura Duo 28 tires)

[@ronykuba]

They are very slow in general.

[@czeckson74]

@@ronykuba Thanks, then i´ll swap them for GP5000s

[@romanpramuka2703]

Tufo Comtura duo are not the fastest, but they have very good puncture resistance and wet grip. On the other hand, their Comtura Prima and Endurance 7tr are much faster, basically on par with other top end tires, and still with good puncture resistance and grip, but for a better price.

[@ronykuba]

@@romanpramuka2703 not really what we’re looking for in a TT tire

[@karolnehring6988]

TUFO - one purchase per life. Last forever (lifetime watt loss also included😂)

[@ronykuba]

Haha 😅

[@vadlme]

Take a close-up video of what you're talking about, instead of a general view of the bike! Thank you

[@ronykuba]

Ok

[@fuji-tk1cm]

RIM BRAKES KILL YOUR WHEELS is only one disadvantage of rim brakes in my opinion

[@matkrek]

Most people replace or upgrade their bike by the time the wheels ‘die’

[@ronykuba]

I would rather not get into that topic
