CityCyclingEdinburgh was launched on the 27th of October 2009 as "an experiment".
IT’S TRUE!
CCE is 15years old!
Well done to ALL posters
It soon became useful and entertaining. There are regular posters, people who add useful info occasionally and plenty more who drop by to watch. That's fine. If you want to add news/comments it's easy to register and become a member.
RULES No personal insults. No swearing.
I think if I had a spill that was so ferocious that I'd bin a carbon frame, I would also chuck a metal one to be on the safe side.
Tubes (round and hydroformed-ish) are probably less easy than panels, but you should see what can be done with a bit of carbon know-how. Check out Lee Wakefield's repair project (find it on FB) with a velomobile that hit a tree at about 40mph.
Steel also gives you a bit of warning before failing, my steel framed fixed wheel felt like the steering and braking had gone woolly when I then noticed the chainstay crack. It wasn't going to all-of-a-sudden give way. The steel bars that broke, it sort of softly gave way, giving me a 'little' advance notice, so I could slow down a bit before it gave way fully.
I saw that video (?? err... MP4??) which swayed me to buy the Dolan Dual over a Titanium frame. I know they don't compare against Titanium but I have seen a few cracked frames online recently.
The thing I like about the original forks is that they appear to be formed around a metal former, which is what has stopped the broken leg going wayward!
What I found interesting about that video is that the aluminium just bent. Okay the frame was useless/dangerous, but was still in one piece so you could still have pootled home to pop it in the recycling bin, assuming the front wheel wasn't jammed against the down tube. The carbon frame just fractured suddenly, which if it happened while riding would be dangerous and possibly painful (fractured bones?).
Also we did not see forks being tested, though I suppose whatever the material, if the fork shears while riding it is faceplant time.
Ok, time for the anecdotal, well I've crashed hunners o' times and my carbon bike is still fine, they MUST be better...
Well, not hunners of times, but I have been hit by a car on my carbon Cervelo, and by another cyclist. Both times the bike went bouncing down the road ahead of me after the impact (carbon does make a horrible noise as it bounces!), and the bike is still OK - I did have it professionally checked after the car hit me.
In terms of longevity, the frame and forks are the 2008 model, and they have outlived all of the other components on the bike which have been replaced at least twice. The bike has done well over 10,000 commuting miles, but has now been retired, and is now my weekend mid life crisis bike ;)
One thing that is a little worrying is that on the inside of the rear chainstays on both sides there has been some wheel rubbing over time, and that has worn through the paint, and left little black indents in the carbon there. I did ask the bikeworks about this issue a year ago, and they didn't think it was an issue.. "I wouldn't worry too much about it, there's plenty of material around that area" they said.
Although I'm obviously not too worried about it as I rode it down the hill in the Dalmeny estate at over 30mph this morning. :-D
So you didn't fix that gear cable then? I did wonder if you'd get to Ferrytoll and then discover one of your carbon pedals was on the CX bike ;o)

Nah, the end on the cable looked different, so I din't want to waste a perfectly good cable by trying to bodge it (I'll get that cable back to you at some point).
I remembered to change the pedal over last night ;)
Can I book you for a push home tonight, my legs are a wee bit sore after this mornings effort? ;)
