So let’s go (I love a good bike pictures topic :D) - and I truly apologize for such a long post
Pinarello Prince FX size 55, 7,5 kgs with carbon clinchers and a PM (now it has Ti Speedplays and bartape, I need to take a proper picture) → built out of lockdown frustration, I use it for fast chain gangs, any hard session, taxing weekend rides, anything. Pure race bike, fast, aero, not confortable, handles like a dream.
Bianchi Infinito CV size 55, built for Paris-Roubaix sportive a while ago, also used for RVV sportives and few others. With Shamal tubulars and FMB 27s for the rough stuff
Now updated to 11 speed before the world runs out of Sram mechanical shifters. 6,8 kgs with deep clinchers, surprisingly confortable for a carbon race bike, even with said deep clinchers. Slightly less fast than the Pinarello, but also less exhilarating to ride when the form is there. Used to be my daily before I had the Pina.
Kinesis GF Ti (rim-braked !), 55,5 cm, 9,3 kgs. Built to replace an old (aptly named) Orbea Aqua for winter / shitty weather. Ti because I wanted something smoother than aluminium and because the price was not such a stretch vs a good steel frame. Rim-braked because I have an inventory of good wheels. Will be 11 speed soon (I have Sram rivals levers waiting in the shed), to be able to use the aluminium wheels on the other 2 bikes without changing cassettes (and because my inventory of 10 speed cassettes is running lower - and also because the current left brake lever is holding by a thread of carbon). With mudguards for crappy weather, good lights for winter, and a (Ti ) rear carrier to shrink a training ride in the commute back home. That came in handy for lockdowns 2 and 3 when the only reason (excuse ^^) for a ride was commuting.
Wheels are custom, Hope (weatherproofed) hubs, 30 mm deep wide aluminium rims (from Duke), CX Rays (20 in the front and 28 in the rear - unusual but the 28 spokes help the wheel cope with the Ortlieb bag that carries a computer, some stuff and office clothes). 28 mm tyres that measure nearly 30 on the wide rims. This bike is not a racer but is efficient under power, and very smooth (but because of fat tyres more than anything else I believe).
Soma Pescadero size 54, from 11 to 13 kgs (weight is no object). Built for the sake of having an allroad bike, kind of old school build with silver components, shiny Paul brakes and Nitto stuff). My most usable bike: from commuting in any weather, school-dropping and errands-riding (I don’t run errands, I RIDE them ;)) to country rides and light-gravelly stuff with the kid (mud quickly becoming an issue with 35 mm slicks and mudguards) and the occasional holiday ride when I only bring this bike. Even the occasional not-too-fast chain gang for the fun of seeing people’s faces when I take my turn
2 pairs of wheels built on Hed Belgium (non +) rims. One with 24/28 CX Rays and Hope hubs with 35 Bon Jon Passes from Rene Herse (magic carpet ride, surprisingly efficient). Cost me a lot. The other one used (but as good as new), 32/32 DT Comp on Campa Record hubs, bombproof build with bombproof Marathon plus tyres (1,5 kgs for 2 32 mm tyres , ride like tank chains ^^) - for less than a new Hed rim
Last one, my old 2009 Orbea Orca, size 55. 6,8 kgs now, from 5,9 in my WW heyday. Had no use for it anymore (obviously with what’s above) but I like it too much so I rebuilt it from parts I had left from the other builds. I now stays at my in-laws so that I don’t have to carry a bike when we go over for the WE.
