carbon bike advice

ive got a question about carbon bikes, im interested in the masi evoluzione series a carbon frame with aluminum fork.
https://www.masibikes.com/evoluzione/evo-apex/

ive been saving up the past couple months but after reading up on some carbon horror stories, im wondering if i should just stick with steel frames,
I live in an area where theres a lot of bumps cracks and holes in the pavement, thats ny for ya,

my question is, with the bumps and all, will that put stress on the carbon frame later on causing it to crack? its a beautiful bike to me, and ive always liked masi, i just dont want to become attatched and then get a crack in it and have to save up for another.
Thanks

The specs say this bike has a carbon fork.
Carbon is comfortable and durable. If it wasn't no one would make carbon bike frames or carbon components.

Yes. By teams that can afford to throwaway frames like you can kleenex. Apply some common sense, hmm?

Actually it is and it isn't - the cf threads are embedded in resin.

Carbon is highly durable. BUT it is also more vulnerable to damage from loading outside its design range than steel or alu. Materials science is a complicated thing...

This is a road bike, yes? As long as the roads aren't so bad that you're not willing to take a road bike with 25mm tyres across them, I wouldn't worry.

That's ridiculous. If a frames cracked during the race, that wouldn't be a very good use of marketing / sponsorship dollars. Common sense, hmm?

Pros break frames all the time. That's why they have back-up bikes.

Carbon doesn't bounce too well, but in normal use it's plenty tough.

Of course, bounces happen...

Bike racing teams have people known as "professional mechanics". Unlike you they'll spot a delaminating frame when they maintain a bike. Which, unlike you, they'll do nightly. The way CF frames fail is to first delaminate and THEN to crack at a later stress. Which you'd know if you'd bothered to find out anything about CF frames...

In truth

1. More depends on geometry than frame material

2. There is no such thing as just cf: the weaves vary hugely, and the bottom of the market frames are very different to those the pros ride. The more expensive weaves have much better performance than the cheaper ones (doh!) Some of the cheaper weaves probably don't have any advantages over alu other than being cheaper to make than a *good" alu frame yet capable of selling at a higher price - which is an advantage only to the seller, of course. A Trek Madone or high end Ridley, otherwise. You really have to compare specific bikes, not materials. (And don't assume that a bike you buy in the showroom will necessarily have the same weave as the factory team bike..)

If you really want a carbon bike, I'd say go for it and enjoy it. I know many people who swear by them.

If it were my money (and my perspective, or course), I'd get a really nice chromoly frame, like a Tommasini Tecno or the like. Or a nice titanium frame.

Like several others here, I think carbon is an amazing material, but feel it is overhyped/marketed in the non-professional sector. In my opinion, most of us really don't see any real benefit from it other than bragging rights on having a really light bike that looks kind of like the pro bikes. I personally do not like how they ride (from the ones I've ridden) when compared to a nicely made steel or ti frame of similar geometry.

The material itself is prone to catastrophic failure if it is damaged, but if kept in perfect condition it should last forever (assuming the CF/AL interfaces are glued well enough). It's your call.

I personally know at least 8 people who have experienced failures of carbon components that have resulted in injuries, and probably a dozen others who have broken their carbon stuff (without injury). I know one person who has busted a steel frame - at a lug - he still rode it to a convenient stopping point. I know 2 people who have experienced failures of aluminum handlebars or stems. This over the past 35 years of being "into" cycling in its various forms. That is enough direct exposure for me to determine that I really don't need to have a bike with a carbon frame, or a fork with a carbon steerer, or carbon handlebars.

Do what you like, but consider the power of marketing in our culture.

I'm a little biased because I prefer the aesthetic of steel, but if you like carbon, buy it!

I think normal riding is fine on carbon. Here are some differences though.

Bike falls over:
Steel - scuffs or tiny dents
Carbon - small damage that may or may not cause failure later

Bad wreck:
Steel - frame or fork bends
Carbon - frame or fork breaks apart

Steel can be repaired by a competent frame builder (fairly common)
Carbon can be repaired by carbon-fiber frame expert (less common)

There is no magic indestructable material. It's all a trade off.

Racers use the latest stuff its part of product development and promotion, to sell the rabble on it,
but they have the luxury of replacing them overnight if they crash or look damaged,
in the team mechanic's van.

Or like Paris Roubaix only see one day of use, then they ride something else for the next weekends race.

but if you want a super-light bike , thats the current technology,
but the consumers get the Asian replicas
because that is what most people are wanting to pay..

I know I've posted a number of BD (Bikesdirect) links lately, but I can't help myself!!!!!
For less than the Masi, you could have another option available to you. It does have a carbon fork (almost impossible to avoid these days on higher end bikes except chromoly). I've heard very good things about this bike. Given your splotchy road conditions, their cyclocross bike with slicks might offer an alternative. BD offers several models in their titanium frame line. These are closest to the MASI in price.

MASI is producing a good quality lugged chromoly steel frame that is a nod to their classics of days past (before they moved shop to Taiwan). It looks like it would make a really nice build for about 2 grand.

Other options on the chromoly front include a classic lugged Soma, or its tig welded, laid back cousin or any number of very good quality offerings from Salsa, et al.

All of this said, you will find that thousands of people ride carbon bikes on a regular basis, and will probably recommend the material for your use. Just wear a helmet.

I keeeeeeed I keeeeeeed...... no, seriously...... carbon bikes are great.....................

The bad thing about this is you seem to have your heart set on this particular bike. You wont really be satisfied until you get it. I say go for it. The bike appeals to you, you think its 'spiffy', and its a carbon bike you can love and take care of. Lots of members on this forum have carbon bikes, and they really like them, so why not you too. Not everyone is into classic steel, or even appreciate the smaller diameter frame tubes, so there is no point in trying to steer you otherwise.

For me, I've been riding road bikes since the 70's, and will never ride anything but steel. Why?...because I can trust it. For me, I would take $1000 of the $1900 you have allocated and buy a cool 80's or early 90's columbus framed italian beauty off ebay in your size and in good condition. Or buy a cool ass lugged steel frame in columbus or reynolds and build it up with whatever you want. But we're not talking about me.

hahaha yeah i hear ya with the helmet, thanks for the info on the other models, i try not to go on biked direct cause ill be on there all day and night hahah, i took a look at the cyclocross and others from different companies as well and i actually like the look of a few especially bianchi and trek but as for the fully lugged from masi, thats my second choice if i dont get the carbon bike cause i have the 1980's version of the lugged steel and its a wonderful bike just a bit small for me
