I replaced the saddle, and I can now sit in a more familiar position. I also removed the Ironman bag and the steer tube looks now really tall... of course, since the frame was made for a full pursuit bar. Anyway, if the position feels right, I can live with the less-than-ideal aesthetics.


I just have to add a bottle cage on the vertical tube... and train to stay "aero" for more than 10'!

With the first triathlon race at the end of this week, it was really time I finished the conversion of my Tri-Ti from 'time-trial' to 'road'.
After some wrenching and part replacement, there it was, ready for its maiden voyage. I tried to reproduce as much as possible the position I have (and like) on my Pegoretti, with the addition of a clip-on aerobar. Following the idea that less is better, I avoided arm-rests and used a flat-top dropbar plus some old Cinelli cushoning elements (originally made as a complement to 'Spinaci') instead. The set-up looked ok and off I went on my usual 'Due Sommarive' 40 km test loop.
Dura Ace (7800) proved immediately up to its fame in the gear and brake department, but I was bothered by the lack of room on my fancy Optima Selle Italia saddle, I couldn't slide back enough without hitting the bottle. A road saddle is surely better if looking for a road position.
Then, when I tried the aero position, I realised I was a full 2 km/h faster than in the drops, but there was no way I could stand that position for more than 10': I was too low, and my forearms were really uncomfortable on the bar.  Generally speaking, I was comfortable on descents but, even in the drops, I couldn't generate my usual power output when pedaling was needed.
At the end of the ride the numbers were clear: I had been 3' slower on the titanium/lightweight/aerodynamic Guru than on my steel/heavy/not aero Pegoretti, on an average day.
Clearly, it was my fault: I'll correct the position, replace the Optima (I'll put that on a shrine I made for exotic components I don't deserve) with an SLR, add arm-rests and try again. Oh, and I'll keep the 'Ironman' bag for triathlon races: without that and without the yellow bottle behind the saddle I could even look like a normal slow cyclist, not a clown between shows ; - )

Coming back from the 'Surf-on Tech Tour' in the US I found myself with a lot to do... to both finalize Caffélatex products AND prepare myself for the racing season.
Travelling and working the way we did, there was hardly any time to exercise (if I don't count the hours standing at the NAHBS..) and there was way too much food readily available. When I'm abroad I love to try local dishes, and in this case 'local' ment hamburgers, meat in general, huge breakfasts... with abundant seasoning and sauces.
When I arrived at home last week, I had a couple of kilos more and two weeks of training routine less: it was time to exercise.
I did a fair amount of swim (we're now training with fins and paddles, quite tough), of running (I'm not 'decent' yet) and on Sunday I had planned an easy spin with Icio. The easy spin became a more serious ride when we were joined by Massimo Moscone, Francesco Melissano, Davide 'Paguro' Fia (local triathlon stars) and Andrea Tibaldi (Alba Triathlon senator and cycling powerhouse). Nice rolling climbs became steep walls as the pace rose in the red HR zone for Icio and me, but all in all we had fun and the pace dropped sometimes, eventually.
I'm still riding the Pegoretti with wheels converted to road tubeless with (prototype) Caffélatex kit: they are so good that I basically forgot them. They also hold pressure like tube-type, it must be the sealant.
I'm planning to have a lighter wheelset converted to road tubeless and use it with the Guru Tri-Ti for the season opening in Fossano (sprint distance Tri).

Thanks to all the people who stopped by our booth, I'm very pleased with how the NAHBS went for Effetto Mariposa. Our new Caffélatex sealant and its 'shake-shake' demo have been real show-stoppers, stealing some attention from the well known Giustaforza torque wrench.
Expect soon updates with all the technical info on Caffélatex... for now I'm just posting a drawing comparing its behaviour with other tyre sealants in the market. Among Caffélatex cool features, I'd like to anticipate the superior sealing effect (ActifoamTM) and the total absence of ammonia (100% tyre and rim friendly, even in the long run).
