    As many will know, I had a spill two weeks ago (http://citycyclingedinburgh.info/bbpress/topic.php?id=10643). I seem to be healing well so I have been thinking what I might do about my bike and I was hoping for some good advice from you folks. There are 3 elements:

    1) Certainty about cause of accident:
    Working out the cause is going to help me get back on my bike with greater confidence. The two main likely causes seem to be:
    - front tyre puncture leads to loss of control
    - speed wobble
    I think the former is the most likely because the tyre was partly off the wheel, I'd recently gone over a nasty cattle grid and the wobble was much more progressive and violent than one might expect from a speed wobble. Also I was probably going between 20 and 30 mph - not that fast.
    I guess to be certain the best way is to look for the (snake-bite) puncture - though I have a niggle that this could have been caused by the being out of control bit.

    2) Taking the bike somewhere to check it over
    The bike seems little harmed by the process (scrape to the saddle) but the bits I'd worry about would be the fork and front wheel. The rim might be an issue for the wheel if the tyre came off on the grid? Is there any point in taking the bike in, especially if I want to replace the fork anyway? And where?

    3) The fork
    I've been thinking of replacing the fork anyway as it has always seemed a bit twitchy on descents (could also be the geometry or me). Many advise to replace the fork after a crash - though the landing may have been softer than mine according to Cyclingmollie. Any recommendations on carbon forks for road bikes?

    Amir It may not have been any one thing but a combination of the factors you have mentioned. As you know I like my summer frame so much I have an identical one for winter use. I have therefore used the same frame with four different forks. The best one is the Ritchey Pro Carbon Road - super stable and very light. Before that I had tried an ITM Millennium 4Ever and it was awful. It caused a series of violent speed wobbles. ITM Millennium and ITM Visio were/are both stable though heavy.

    Another factor you might consider is the semi-aero wheelset you have. I have not used aero wheels but I got through a couple of sets of CXP33s before switching to Open Pros. Even though the CXP33s were only just an aero shape they used to get grabbed by side winds much more than the Open Pros do.

    The Ritchey Pro Carbon comes with two rakes 43mm and 45mm. I will try to find out what mine has.

    I can sympathise on not 'trusting' the bike
    I stripped my bike down to give it a thorough check over (once the body allowed!)
    Even now I still give it a once over looking for cracks etc most days
    realistically if I could have financially done it, then I would have replaced it
    sadly the crash hit me financially for various reasons and my partner getting laid off twice was the nail in the coffin!

    Thanks cyclingmollie - I'll think about the Ritchey fork. It's pretty expensive though. The semi aero wheels certainly aren't great in a cross wind - maybe that will be a second replacement, once I've saved up.

    I've checked the inner tube - oddly the (main?) puncture is on the inside - looks like a small slit. I haven't yet looked fir any causes or secondary punctures - I still get quite dizzy.

    Thanks custard - I am both looking forward to and worrying about my first ride again.

    amir: "I still get quite dizzy"

    That's not good to hear. With the shoulder and all the road rash as well, yikes.

    Maybe try just a non-aero front rim?

    Sorry to read about your off amir. I can highly recommend aiming for waterlogged ditches when control is lost - muddy, but slightly more forgiving...

    Puncture on the inside, especially a slit, would suggest either a sneaky spoke poking through the tape or a snakebite to me. Although my inner tubes always seem to end up twisted anyway, so the inside of the tube may potentially still have been against the outside of the tyre.
