    Probably overtorqued at the stem.

    Crash damage aka why you shouldn't bother with carbon bars.

    There doesn't seem to be any other damage, which would make it unusual.

    Also, I've seen carbon bars on mountain bikes survive massive crashes (including one which ended up bending a wheel in half), so they're not useless by default.

    I'd imagine there's a world of difference in the weave of a carbon bar for mountain biking (requires strength as much as lightness) and for roadies (I need to shave ten grams off my bike's weight for the five mile commute)

    Psycho got it, it just gave and he went flying, cheap carbon bars I guess.

    He's sore but nothing broken.

    Maybe not that day, but I'd be surprised if those bars just gave way without any previous incidents causing damage to the fibre. Carbon doesn't snap like that JRA, but anyone every time a picture like that gets out on the internet the dude posting forgets to mention the crash they had 2 months ago which shredded the bar tape, the same crash that made him put that brand new Fizik tape onto the Corratec factory spec xxyzx finishing kit.

    They do, but generally because some fucking idiot has tightened the stem to the point that it's utterly crushed the carbon.

    Torque wrenches, they've heard of them.

    Hey chaps - time for another of my annoying questions.

    I'm looking to replace the sludgy Marathon Plus tyres on one of my single-speed bikes. 700 x 28c. Any recommendations for something faster...MUCH faster?

    Rubino Pro Tech come up in 28s, should be a faster tyre than the M+. You'll find more "pro peloton" options at 25mm though.

    25mm will be okay? I've never really understood the min/max tyre size thing when it comes to wheels. They're Halo Aero Rage wheels. Cheers, Els.

    Believe it or not, that's not exactly true (assuming equal inflation)... but the science is a bit long and painful to go through here.

    http://velonews.competitor.com/2012/03/bikes-and-tech/technical-faq/tech-faq-seriously-wider-tires-have-lower-rolling-resistance-than-their-narrower-brethren_209268

    That gives an overview. There are more detailed articles out there if you want to get into the nitty gritty.

    Edit - and now my post looks odd as you deleted. :D

    Hmm, that's a good point. I fucking hate even slightly rough roads rolling along on my 25mmers. Theoretically a smaller more circular contact patch will waste less energy deflecting on a perfect road than a wider one of equal area, because it also deflects rubber at its edges, which are greater, but the fact is none of us ride on perfect road surfaces (which would be pretty lethal in practice anyway), so the effect of undulations in the surface must be considered.

    So, I guess the only benefit of thinner tyres is it's quicker to pump them back up after a puncture. That, and I don't have to undo my v-brakes to get the wheel out, as it's the same width as my rims are apart. Unfortunately, I don't think my favourite tyres come in anything wider than 25mm.

    Cubby didn't know how to turn off sigs!

    Go for Continental GP4000 IIs in a 28mm, or Continental GP 4 Seasons. Both are excellent tyres.

    If your happy on 28s stick to 28s, I just meant that the tyre companies gear their high end rubber towards the professionals demands so if you want performance compounds and high thread casings you have more options at 23/25mm. Most 28mm customers are interested in durability over cornering speed.

    That's why I deleted Psycho, I did a quick search and didn't really find any evidence in it, things you get told eh that you believe for years isn't really true, anyway I came here to post this.

    Only in Canada.


    Bloody did the fall yesterday, ripped my brand new bar tape as well. :(

    It was my unclipping foot (curb side) that I couldn't get out, for some reason it felt tighter than when I first used them RHS was fine but the left side was tighter, anyway I've done some adjustments and I've put some black electricians tape on the bar ends to hide the tear, did both sides so it doesn't look odd, doesn't look to bad if I do say some myself, I got a scratched bloody knee from it. :D

    Didn't say if the bow tie was reflective or not. I just hope it shrinks extremely quickly when wet.

    Gears? ;)

    As for falling down with clip ins, I only tried them once for a long weekend trip I did around Scotland, about 200 miles over a long weekend. I had several major incidents where I fell over after having to stop suddenly and getting stuck. I buggered my knees...though that might have been the distance.... Never gone back to them. I have dual use pedals on my road bike, but not tempted.

    Good run this morning, a good climb following last weeks Glasgow-Edinburgh along the canal. A friend had described the run as "undulating"....but it was more uphill for 13 miles, downhill for 13.

    Partial build of the bike. Discovered that's there's almost no clearance between the spokes on the wheels I had built and the fork I bought. Unusually wide hub flanges, madam. So that'll need sorting out.

    Other than that, went OK. Mudguards are a right pain, but a worthwhile pain.

    Question - do you guys have specialist insurance for your bikes, or do you just assume it'll be covered under house insurance.

    My bike's worth less than £700, but it's fairly common, so supposedly more attractive to theiving scum. And having watched the Cycle show last week, the section on how long it took their tame theif to get through cables and D-locks was pretty depressing.

    I'm not in the habit of leaving it anywhere for more than a few minutes if I'm in a shop or so on - certainly don't leave it anywhere all day, but I'm wondering whether bike insurance is worth looking into.

    My garage got broken into and none of my bikes were pinched. Therefore I haven't felt like I need to insure them specially.

    If I had a really good un though, I would. But I wouldn't have one cos I don't like the thought of having a bike I couldn't chain to the railings without worrying when popping to the shops.

    I have them covered as a standalone items on my house insurance, also specifically as items away from the home.

    Specialist cycle insurance is good if you commute or travel long distances, but for everyone else it works out far better value to do it through contents.
  • Deleted user 1 September 2014 13:47:46
    Also, ETA are great for bike insurance.

    My Specialized MTB is nearing 12-13 years old now. I almost *wish* someone would steal it TBH. It's wearing so well I'd quite like someone to half-inch it, so I could justify buying myself a new CX bike of the type I keep lusting over!

    One 'mate' taunts me by pasting up links regularly with nearby ebay auctions and other new release details, but I've stayed strong so far. I should just buy one, but the wife would probably have a hairy fit if I had three bikes.

    To return to clipless pedals, I wouldn't ride my road bike with anything else these days. Just a difference from using the toe clips that came with it. You just need to persevere with them and get used to it, honest.
