PS. When I provide a link here to gear or equipment I sometimes get a kickback from it. But I NEVER link to something that I haven't used or did use and didn't like! 👍
im stil riding my 2014 propel, will watch this with interest, I havent ridden many kms.
Hi Jourdain, how long did it took for you to recover from epididymitis? Thanks
Much appreciated brother
Monocoque doesnt mean "one peice". It just means that the structural elements are integral to the body. So you can glue as many pieces together as you like as long as the body is all part of the structure. Not molded all as one necessarily.
He really doesn't know anything and has no business acting like a bike/cycling expert
Rob the Door Knob carbon bike repair reckons he is a doctor and scientist role into 1. Referring to impact as trauma and his monocoque explaination are a joke. Rob the door Knob. 😂😂😂😂
Thank you for this very informative and professional breakdown. Awesome stuff. This geeky science stuff what made me subscribe to this channel at first place.
6:30 appreciate the warning :D
Muito bom trabalho, ansioso para ver quadros og-evkin e lexon
Any chance to test Polygon carbon frames? I am the proud owner of a Strattos S8. Every cyclist advised me not to buy this bike... tbh I'm not a skinny guy and this frame seems pretty solid, no problems carrying my weight which is 98 kg. I'm very curious to see how good their frames are. It's a pity that they only offer a 5-year warranty.
Interesting video, thanks.
Glad you enjoyed it
Very interesting 🤔
Glad you enjoyed 👍🏽
1st: This is not flagship, Giant's flagship will always come with ISP.
2nd: Surprisingly how the clean is the internal of the frame. I have see quite a few v4xs and Dxgma F with significant more leftover resin and carbon compared to this.
Not a massive fan of those ISP's... frustrating if you want to sell the frame. I have a TCR frame with ISP so I'm intrigued to see how it rides once built 👍🏽
@@JourdainColeman Nice, I do think you will be a big fan of the ISP in term of how they ride. Yea, resell is a problem if you have cut off too much of the seatpost, but I guess resell value is never a consideration for any bike brand.
@@Chris-iv2ud I have both and maybe it is a placebo effect but non isp frame feels a little more comfortable on rougher terrains and on country roads. On smooth new pavements, both climb about the same. Maybe if you climb for an hour then you might start catching the difference, but unfortunately, we don't have such long climbs here in Wisconsin. Also SL frames are made in climate controlled rooms while these non isp frames are built in regular factory set up so sometime you may even see dust particles on a brand new frame. :).
Hiii, do you know anything about bicycles from Twitter or about their carbon frames in general?
I've not used them before but a lot of people have commented. I'll Maybe see if I can get one this year as there seems to be a lot of demand 👍🏽
I heard the lack of weight in listings is to avoid potential litigation if the weights vary, which they always do. I thought it was more specific to certain countries though (e.g. US).
One would hope they’d be able to keep the weight within a ±10% range or something.
You are very much correct. The problem is that these mid grade frames are not made in climate controlled rooms and therefore carbon cures differently during summer and winter months based on the air humidity and room temperature. I believe only SL frames are made in climate controlled rooms hence have more consistent results while the lower grade frame will have different results during summer and winter months. I wonder what month production frame will be the best to buy because not everyone may enjoy ISP frames.
It's more to not deal with complaints. Nobody lists their frame weights with a promised weight. How many lawsuits have you heard of due to frame weights?😂
wow i still remember 3k would buy you a top of the line bike, nowdays is just crazy
A Lamborghini used to cost $10k. Things change😂 I was selling +$10k bikes over 15yrs ago. Its pretty remarkable what you get for $5-8k these days. A WIRED SRM used to cost $5000, and Zipps that would melt on long descents were $2200. Now you can get a bike with a power meter and aero wheels for $6500-7000 without accounting for inflation
I woulnder if abyobe repairs those warranty write offs
I want a frameset built by Rob... (or tucked together from all of the dead stuff lying around in his attic)
Advanced pro was mid grade, not top of the line- that’s the advanced SL frame.
I wish I could find those cutted frames around me. Buying it 60£ and then I'll repair it. It would take 200gr but who cares...
I am confused. Since industry changed alloy to Carbon dropout he doesn’t see people needing to repair that section anymore…
So this should be a good thing right? Then why is he not fan of Carbon dropout?
Hi, please reply my emails, I never heard back from you regarding the progress of the test of our bike.
How is it possible to be the top of the line bike for 3k pounds? Are you sure about this? It seems too low for a top of the range bike.
The Propel Advadnced Pro 0 are top of the line frames. That 3k could have been just the frameset to be honest but getting info online for new prices isn't easy. It was also 6 years ago so factor in inflation and how crazy the bike industry prices have become and It seems about right.
@@JourdainColemanthe advanced pro frame wasn't top of the range. That was the advanced sl with the integrated seatpost. I had the 2016 advanced pro 1. It was 2600 with mechanical ultegra and 50 mm carbon wheels.
No totally scientific frame shake?

I think it isnt really correct to say that the frame is 6 years old.
That Propel carbon frame was launched in 2014. And noe its mid december so I think it’s more fair to say that the frame is almost 10 years old.
enjoyed the video as others as always tho! Would be cool to cut a Giant Defy 2024 in half and compare : )
top end aluminum beats out cheapest carbon every time, and you save money too
Aluminum is garbage. I will never go back to it.
Giant's carbon frames are OK for the most part, but yes, I totally don't mind riding high-end aluminium.
grams suck
Yawn 🥱…
Same stuff each video … either cutting up a frame or building up a Chinese bike 🥱
So why are you here
@@valiantabello Well you have to watch something to form an opinion? Or is that not allowed?
You having watched this video and interacted with the comment section prompted the algorithm to recommend this video. Cheers mate.
bravoooooo
