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

Yeah but most guitar people probably know something about guitars. 🙂

Generally speaking, yes, but you might be surprised how many know very little.

My carbon bikes scare me to death. I keep adding more carbon just to try to make them safe, but I’m still afraid of them assploding.

Steel is worse because those welds might fail, and then the frame would just fall apart. Aluminum cracks, dents and bends.

I thing a wood frame would be best. But, it’d have to be a good, solid wood like Oak.

No, I would want ash from the same forest that supplied the wood used to make Robin Hood's bow. So I can have a bike with "provenance."

Why don’t you spend $1,000 - $1500 on an aluminum bike. You won’t have to go cheap Chinese, and will get much better components than a comparably priced CF bike.

Agreed, a top of the line alloy bike will be better than a cheap carbon bike.

Yep, agreed. A decent alu bike will have better components than a similarly-priced carbon one, and will still have an excellent frame.

A few years ago when Trek introduced the Emonda ALR they also offered the Emonda S which was carbon. They have since discontinued the Emonda S and only offer the SL and SLR which are more expensive. This way they don't have an alloy and carbon fiber bikes competing against each other... the ALR was the better bike in that price range.

When I was looking for a new road bike a month ago I was intent on getting an Emonda ALR but there were none to be had in my size, and no more on the horizon. I ended up getting a Specialized Tarmac SL6, for about 1400 bucks more, with the same 105 groupset the Emonda had. I dont regret it at all because the Tarmac fits like a glove and rides great, but I would have bought the Emonda, if available, and if it fitted.

Before I got the Tarmac, I actually had a BMC Teammachine ALR 2, with 105, but returned it because the seatpost kept slipping. The BMC carbon equivalent to that bike, the SLR, was about 1200 bucks more than the ALR. I could have got that but by then I'd lost faith in the fancy, internal, seatpost bolt system the BMCs have

Yep, I was looking at the Emonda SL back in late 2015 when the ALR first came out. My LBS had gotten a couple in and one of them had this almost non-existent tiny little ding at the rear of the top tube. The bike was still in the box and they were planning to send it back to Trek. I loved the color, and I told them I was interested in it, and I knew the frame dimensions were the same as the SL, so it should fit me well. After they built it up and I took it for a 10 mile spin, and I was like, yep, this is coming home with me. I had a Carbon Synapse that I hated which is why I was looking at the Emonda SL to begin with and since I had the Synapse on my car at the time, I just had them move the Ultegra 6800 group from the Synapse to the ALR and I put the 105 on another bike. As luck would have it while I was sitting in the shop shooting the crap, I sold the Synapse frame to a guy looking for a carbon frame only. Win, win, win for all involved. The ALR is a fantastic bike and it weighs 16.1 lbs with pedals which was less than the Emonda S and SL. I also put a FSA SL-K seat post, Stem and handlebars to sweeten the ride.

You are completely missing the point. CF is not more risky than any other material used to build bicycle frames.

This might wreck you...aluminum bicycle frames break, too.

In fact our bodies are made up of Carbon mostly if you exclude water percentage. Even with water, it is still the 3rd most abundant material. In fact all organic life is made of Carbon and it is what that gives stability to the bonding inside us.

I was also nervous like the OP but then I started talking to carbon in my body and they said "look at yourself, you will be just fine man."
Well, I have to see that when I crash on my upcoming Carbon bike

I have ordered my first Carbon road frameset (highend). Should be coming by end of next week.

But, your body does not contain epoxy resin. That stuff is like a ticking time bond.

The OP's concern is not uncommon. By far most of the "Is this scratch / nick / cigarette burn safe to ride" threads on BF are for CF frames and parts. Even if one may not fear serious injury/death due to catastrophic failure, they may be adverse to the costs of replacement for what may be considered inconsequential damage on metal bikes. It is a valid concern.

Now of course we do not have industry experience (like you do) so perhaps the $1,000 point is not the threshold between safe and unsafe. But your next post (#65) seems to reinforce, rather than contradict, this concern.
I'd argue there isn't a price threshold that truly indicates safety....

Eh...I take that back - if someone is offering an unknown chinese frame from $50 then I'd avoid that like the plague.

Do you know the term "clickbait?"

There are millions of carbon bikes ridden every day, millions of aluminum bikes, dozens of titanium bikes ... all using carbon forks. Some of every kind of anything is going to have trouble. The are plenty of wrecked metal frames too, just no one is trying to scare you about them. Probably almost all carbon failures happen to something that was already damaged in a crash and usually showing signs of trouble. That part is always left out for dramatic effect - it asploded for no reason!

I'm about to take my carbon bike with carbon brake levers out for a scenic loop. Sure hope those brake levers don't break for no reason. They haven't for lots of years and people have looked at them wrong, so I hope I'm ok. If you never hear from me again, don't buy carbon.

People have been using metal since the bronze age, it isn't new and mysterious. You're spot on about the fact that all frame materials fail, all very rarely. I think it's like how a lot of people are afraid to fly and drive instead. The facts are clear but people can't shake the feeling...

People who are afraid to ride a CF frame with a scratch or nick don’t understand the fundamental material properties of CF.

Is that $50 before or after using the $2 off coupon?
