content: Sure, I did it(really? yep)I swapped a second hand full carbon road bicyclePinarello Prince 2015(900-1200 euro) for a titanium frame, Columbus' steel forks and Campagnolo Victory 70s, brand new old stock headset.I know, I know ... Carbon is considered *THE* futuristic material enjoying a high status, indeed, at the moment, Carbon dominates the high-end cycling segment, but Titanium has a lovely and unique color and appearance.I couldn't resist-Road bike forks have to be light but also stiff and somewhat compliant, a very difficult task to accomplish on a 80s style road bicycle.Carbon forks would probably be the perfect choice to keep things light and stiff, but it doesn't match the retro-style (and I don't like Carbon).Titanium forks cannot offer the needed strength without extra material and thus weight and bigger profile.So, to keep forks slim I had two choicesVetta's aluminum racing frorksMoser's racing chromed steel forks

content: Carbon, aluminum, steel, titanium.... People have their preferences and that's what makes the world go around. Plus, obviously the "low-end" department store bikes are going to be made cheaply out of steel/aluminum.I have a Tommasini steel bike (Columbus SLX tubing) bought in 1990 and upgraded over the years. I also have a Pinarello Dogma (carbon) bought in 2011 that I currently ride. My preference between the two is the Pinarello because it is lighter, stiffer, yet has a smoother ride.The only downside with these "vintage" bikes is that they are becoming less compatible with some of the current component standards, for instance disk brakes and internal cable/wire routing. Plus, the trend is now towards wider wheel rims and tires and these may not fit between the narrow-spaced chainstays.I don't want to turn eevBlog into a bicycle forum, but I've attached pictures of the two bikes for those that like to look at pictures of bikes!

content: Your Pinarello Dogma is similar to the Prince 2015, full (modern) carbonridden it for 600 km (3 days trip, 6 stops), then I tried a C4 Air One 1998, full (monocoque) carbon.ridden it for 400 km (2 days trip, 3 stops)Cool bicyecles, and modern, but for me, titanium frame + steel fork is the best for endurance for long distance travel.But, 700x20 vs 700x25 vs 700x30?is that the kind of evolution we need to care about wheels?My old Olympia had 700x19c (palmer) ...ah, so gold old good days ...

content: You can get light titanium forks, however, I wouldn't do it as you are trusting some noname brand:https://www.ebay.com/itm/271143626844https://brainybiker.com/carbon-vs-aluminum-fork-comparison-and-analysis/https://brainybiker.com/carbon-vs-steel-fork-comparison-and-analysis/If you are up for flashy colors you can electro anodize the titanium frame to give it an interesting look.Solid colors are quite easy. Fades/patterns with consistent vivid colors are very hard, and require a lot of surface prep.Just need a power supply and some baking soda.

content: There's audio-phoolery, then there's bike-idiocracy.A friend is also on this bike thing, crazy expensive and more delicate than wet paper.Everything is under-engineered under the excuse of reducing weight and will break under light use. Don't ever think on falling!Saving 10grams on the wheels nuts using almost transparent aluminium nuts with 0.5mm pitch threads that will break when shouting at them.Suspension have no bushings, bearing or grease, because you know, more weight, so aluminium rubbing aluminium, won't last 3 months without new parts.A 1mm bronce sleeve would last for ages, but again, theywouldn't sell so many repair partswould add 10grams, so many mass could become critical and break the space-time.That people becomes so obessed, that they will spend hundreds for saving 50-100grams."Whoah it feels so light now". Placebo effect at its finest.Every 300km something else breaks and he will always repeat the same thing, trying to convince himself, "Hey It lasted 300Km, that's great".They definitely found a way to make people waste their money!

content: You might want to specify what brand this is.No major brand uses aluminum screws for the chainring/disk brake/stem/etc that I know of. However, tons of after market aluminum screws and completely unsafe light weight parts are available.Thru axles use aluminum threads, but its a 1 to 1.75mm pitch, and quite thick aluminum (12 or 15mm).
