Aluminium frame quality difference

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

It depends on who the one is.

If the one is riding with less than 100 watts (<2 watts/kg), probably not much.

>300 watts or 4 watts/kg, most likely very noticeable.

They sell that brand on Wish. It's described as a lightwieght racing bike of about 35lbs. If a clone of anything, it may have better survival of a car wreck .

Look closer: stem shifters.

Bikes: 2008 Cannondale Synapse -- 2014 Cannondale Quick CX

I have a Cannondale Synapse Aluminum frame from 2008. If I were to pick things to change about the bike the frame would be the last piece to go. It's a great frame. I can only assume they've gotten better in the 10 years since it was manufactured. After thousands of miles and many other components that have been replaced for wear or upgrade, the frame has a few paint chips and scuffs, but no dents or signs of needing replacement. I ride in hilly conditions. I ride at night often, and occasionally even with good lights I fail to spot road hazards. The frame endures. I had a peak weight of 215 and am now at 184; the frame handled both ends of that spectrum well. I toss a Tubus Fly Evo rack on the back and load up with my laptop and a change of clothes sometimes to commute. The frame handles the load fine. But when I want to be nimble, it's just fine too.

I suspect my next road bike will be CF. But I also think I'll always want to have an aluminum frame bike around too.

It's Just Business..

After making bikes for Specialized, for years, Merida bought into their customer company,

Merida has enough production capacity left over to make more under their own name too,

and sponsor bikes for pro teams too, under both brand names..

Umm no. Maybe in design development. Not even close in production.

A lot of track bikes are made out of aluminum. Aluminum makes for a light stiff frame that is durable and somewhat aero. It is also less distressing if you happen to fold it up in a spectacular crash in turn four.

actually the shifters are mounted on the handlebar. unlikely to take any damage in a spill.
I am looking at the frame design not the build.
components can always be changed.
it would be interesting if the frame had downtube shifter bosses.

I think some of the Cannondale bikes coming to Europe were assembled in Vietnam sometime ago and possibly Cambodia now this is to avoid EU anti-dumping duty. Cambodia is the biggest exporter of bikes to Europe followed by Taiwan I think but most of the components are made in mainland China but it depends on the price point. Fuji-ta are a huge producer of both complete bikes (20 million a year) and certified frames to be assembled elsewhere in the world including low cost countries in the far east like Cambodia and Vietnam. My point is a bicycle can have a frame made in mainland China and be assembled in Taiwan or assembled in Cambodia with basically the same frame. Looking at fuji-ta site the first page has a video clearly stating Cannondale as the first brand. Cannondale is a Dorel brand. Taiwan is seen as the highest quality bikes in the world nowadays so connecting your brand with Taiwan is a good thing. Having your final bike assembled in Taiwan is seen as a good thing. Wouldn't surprise me though if top end Cannondale frames are made in Taiwan and lower end frames are made in mainland China this is a formula used by many western brands that don't manufacture frames themselves now.

I don't think fuji-ta the world's biggest high quality aluminium frame manufacturer uses 7005 now or if it does its for specialist orders, they use 6069 for their premium frames. Lastly I remember reading on alibaba a factory that stated it now made high quality aluminium frames of 6061 and had stopped making inferior 7005. On face value 7005 is stronger but 6061 allows easier hydroforming and shaping of the frame so can more easily localise in the frame strength and flexing to improve it's overall performance. I believe 7005 tends to be more brittle and fatigue more. It naturally air hardens over time faster making it more brittle even without use. 7005 can have a higher strength to weight ratio but beyond that I think most of the positives belong to 6061.
Yep, I have a 7005 frame from the 90s that has less head tube than it used to due to a crack... lucky I noticed it in time, and there was enough spare tube past the weld. Actually I'm sort of grateful; helped me slam it more

Fuji-ta
As I said earlier I knew the people who came to Taiwan from C'Dale to train the welders in Taiwan to make their frames. They may have moved this to China, I don't know.

More likely, they are still welding in Tainan - where I live - and using Fuji Da as an assembler.

Yes. I saw the video.
