@GrahamNicholson56 11 месяцев назад

A story I heard from a pro team mechanic; the team were getting a lot of top tube failures following crashes in the peloton. Strangely the riders weren't involved in the crash. Instead they were caught behind the crash and spent their time sitting on the top tube waiting for the road to be cleared. The frame wasn't designed to take their weight in that way and a lot of very expensive frames were ruined.

@Garfie1d73 11 месяцев назад

@username8644 11 месяцев назад

I wouldn't say the frame isn't designed in that way, rather the frame is being made way too fragile in order to make it as light as possible. An aluminum or steel frame will be perfectly fine, even though it wasn't designed for it either. Just a problem with carbon fiber and the way the weave is pointed along with it being made way too thin and fragile.

@philipcooper8297 11 месяцев назад

@@LazyGrayF0x As some might mention, most of the bolts on bicycles are from 4Nm to 6Nm max... that is a very low torque value. So some might find it insufficient and add way more, which can and does introduce hairline cracks in carbon fibre composite parts of your bike. In fact, it can be very dangerous as well, as the now damaged weak point can fail under stress while you're riding the bike.

@leissp1 11 месяцев назад

As someone who has steel frames, Alunminum and one carbon frame your tips are really useful. I think the chain catcher was invented for carbon frames. I like the Carbon frame a lot but worry that I will damage it beyond repair. I have also dented a Steel frame top tube by clamping it. The newer steel frames are really thin. To protect my frames I use the Silca Hirobel frame support or the Park PRS 20. I have always used dummy hubs when travelling. Thanks Alex

Why all front derailleurs don't come with a chain catcher is beyond me. I've got them on all my bikes. Another tip- when leaning your bike against a stationary object or wall position the drive side toward the wall. That way if it does fall over it won't hit on your derailleur.

I use the top tube for my bike stand and balance the bike (Dogma F10 disc) with wheels on and only loosely close the clamp. For most jobs, that's all the grip strength I need. My stand clamp's length and my seatpost height above the frame are a bit in conflict. But great video as always, Alex!

@stevengagnon4777 11 месяцев назад

Find away to use a seat post. The rocking end to end ....not good either...mark the seat post and don't extend beyond max height . This really applies to all bicycles reguardles of the material . Also do not trim off too much from the seat so you can safely extend to clamp it in your stand.

@BicycleForHealth День назад

Respectfully- some of this is rubbish. If a carbon bike cannot stand falling over then carbon shouldn't be used as a frame material. A carbon frame is harder than steel when made correctly. There is a video here on RU-vid of a guy slamming a carbon frame onto a concrete floor multiple times over his head and it doesn't brake. Would I want to ride a frame abused in such a manner? Of course not. But if a carbon frame is so fragile that falling on the ground is going to make it snap, then the bike manufacturers should be sued out of existence. This kind of rhetoric is why so many people are scared of carbon. This is why I stayed away for so many years! I recently put about 8,000 miles on my first carbon frame. My previous bikes were all aluminum. I've hit potholes at high speeds with my carbon bike that were big enough to hide a small dog in. Uhhh- hello. Carbon is used for mountain bikes that go airborne and slam into the ground from several feet up. Yes, I know the MTB frames are more thick and they have suspension. But it still shows the strength of carbon. Personally, I will never go back to aluminum after seeing how strong a well-made carbon frame can be and how well it absorbs vibrations. I've ridden bikes with shock absorption on roads that transfer more vibration that my carbon with no suspension. And that's a fact. Mine is made in Taiwan by a very well-known company that everyone would recognize.

@almin9751 11 месяцев назад

Also the maximum insertion is a thing to not touch the cutout...if a person is just too small and introduces the entire seatpost it could be not complying with the manufacturer min/max insertion, in Specialized's website the Tarmac user manual is at bottom for download and reading. I cut my seatpost since after my measurement still had a lot of tube so i got it at right measurement and comply with manual and reducuded 20 grams 😅

@iammarkstewart 11 месяцев назад

This is something to check for if if your seat tube is a non-straight tube. Some Cervelo's have this "problem"...you need a relief cut in the back of the post to avoid a load point on the back of the seat tube curvature. A shop I worked at had a customer bring in a used purchase that ended up with this problem (crack in the back of the seat tube), and it turns out it stemmed from improper build protocol when the bike was new. A lot of things inside bikes even when new that a lot of people are not aware of.

Frames are painted, so the first thing you chip or rub off is the paint. Then carbon is put on in layers of tubes - scratching one layer doesnt cause a problem same as scratching a solid metal. You just scratch some carbon tubve thats independent of other in the array. Avoid crushing or chipping carbon, surface scratching the outside layer wont do much damage.

@@julianallen515 With only a thru-axle in the dropouts, the only points of contact are the threads and the outside of the left dropout, with no support on the inner sides. When a hub is installed, it provides support on the inside of the dropouts, preventing dropout squeeze. When I said junk hub, it can be a decommissioned hub, but still allows you to install it onto a frame mainly to provide dropout support.

Yeah, that doesn't work... it's the hub shell that prevents compression - not the through axle (otherwise your wheel would never be tight...)

It seems like it would affect a lot of riders and the fires/explosions from these new batteries are amazingly hot. Thanks. M.

@BicycleForHealth День назад

What did you end up buying? Respectfully- some of this is rubbish. If a carbon bike cannot stand falling over then carbon shouldn't be used as a frame material. A carbon frame is harder than steel when made correctly. There is a video here on RU-vid of a guy slamming a carbon frame onto a concrete floor multiple times over his head and it doesn't brake. Would I want to ride a frame abused in such a manner? Of course not. But if a carbon frame is so fragile that falling on the ground is going to make it snap, then the bike manufacturers should be sued out of existence. This kind of rhetoric is why so many people are scared of carbon. This is why I stayed away for so many years! I recently put about 8,000 miles on my first carbon frame. My previous bikes were all aluminum. I've hit potholes at high speeds with my carbon bike that were big enough to hide a small dog in. Uhhh- hello. Carbon is used for mountain bikes that go airborne and slam into the ground from several feet up. Yes, I know the MTB frames are more thick and they have suspension. But it still shows the strength of carbon. Personally, I will never go back to aluminum after seeing how strong a well-made carbon frame can be and how well it absorbs vibrations. I've ridden bikes with shock absorption on roads that transfer more vibration that my carbon with no suspension. And that's a fact. Mine is made in Taiwan by a very well-known company that everyone would recognize.

I would also add not paying attention to recalls! It seems like every week there is a recall for a carbon handlebar out there from a major company. And it isn't like automotive recalls where it is one person has the issue out of hundreds, a bike handlebar is a very key part of the setup unlike a seat clamp on an automotive. Torque spec is another one that is a given and not mentioned here. Another reason against leaning your bike up against a wall is that it can press on your electronic shifter and wear down your battery since it is constantly making contact and sending a signal.

@pakelly99 11 месяцев назад

Came here fully expecting mention about not sitting on carbon frame top tubes. Arguably, it could be an item if there’s ever an “other things you’ll see pro’s do, that we shouldn’t seek to copy”. Albeit it looks cool, is comfortable, it’s something with substantially different connotations as a paid rider with a constant stream of free equipment, on the one hand, versus a member of the public who pays out of his or her pocket for every item they use. As someone else referenced, pro riders can break frames all day from here until San Gennaro, no worries, seven times in the one race. (Typically) that’s not something we can emulate, and latent damage to a carbon top tube is no joke at any time, but making its presence known at the most inconvenient time, equally, could literally be fatal. ☠️

The last one, seatpost being put in incorrectly, is actually out of our hands when it comes to frame manufacturers using proprietary seatpost that come in only one length. I have a 2020 Giant TCR Advanced Pro that I can't ride because Giant decreased the seat tube length 2 cm, changed the clamping system to be hidden, but put stress on the seatpost in the wrong way, and a proprietary seatpost that was too short to make up for the shorter seat tube. I got stuck going right to the minimum insertion line and broke five seatpost. My older 2011 TCR Comp has a proprietary seatpost but a taller frame and better clamp system. Not a single issue on it.
