      Is it any wonder Cannondale recalled 11000 of forks / bikes, yes.. ELEVEN-THOUSAND forks have been recalled because of cannondale's greed and lack of quality control. When was the last time you saw 11000 steel, titanium or aluminum forks being recalled? and yes, the Cannondale bicycle recall was due to FORK FAILURE.

    I have a review of Specialized's expander plug which you can get at any Specialized shop or online. Unfortunately, the Specialized plug is not "floating". It sits at a fixed height from the top of the steerer tube, so it's really limited as to where you can support the stem clamping.

    My 1 year old Decathlon EDR CF 105 bike has a similar problem. I use torque wrench for everything carbon related, but since the original expander was tiny tiny thing inside the fork and a massive gap from top cap with a long M6 bolt to 5CM below, the top of the fork slowly started to get crushed. I have now bought a PRO expander that's only 20g heavier, but fully hugs a very long tube. Likely I need to chop about 1CM from the top of the fork to have a cleaner fork and even have an extra spacer right below the top cap. The new expander already gives me a sense of security that I won't fall off the bike at 70km/h downhills.

      This the correct way to do it. You torque carbon to the amount needed, not the max. If nothing is slipping or creaking you're good to go. Also you have to consider, how the hell does a stem manufacture know the safe amount of torque can be applied to your steerer? I would not trust that torque spec. printed on stems.

      Always use a manual click type torque the reason is you can feel the torque as it clicks for you to stop. Your body is 1 million times more sensitive to torque forces than any digital torque wrench up to the point of the click. This is why I always use a manual torque wrench on bikes.

      In realit ty the original Cannondale is gone, it's now a brand of the Dorel corporation, even the Cannondale test centre is closed. I don't know who makes Cannondale branded bikes nowadays but it isn't Cannondale it's imported from a factory somewhere in the far east. I guess different factories are used for different price points. Many classic bike brands nowadays are basically importers, the factories themselves dictate most of the specification especially for mid range and lower end bikes where costs are more critical.
      As for carbon fibre it is a high performance material. Like a sports car reliability and safety is compromised in the name of performance. What I find strange is with CF forks being by far the most dangerous CF component why aren't more bikes sold with CF frames but steel or aluminium forks. Surely better to have a CF frame and aluminium forks than aluminium frame and CF forks. If the frame starts cracking you have a chance of stopping and controlling the bike but CF fork failure can easily kill you.
      Personally I can't justify CF frames or forks, I'm a heavy rider and the weight savings would be utterly pointless for so many reasons.

    • @event4216

      Especially if fork is not exactly biggest part of bicycle....so where they are saving - weight, material or labour? Enhancing weight balance and riding characteristics? Tell me someone, please. To me, Ti frame with CF forks is like new car, sold with emergency wheels - they are lighter than full size wheels, but they compromise whole set. Titanium frame is much bigger than fork and they decide to make that small, but important part out of composite material....what's the point? Professional competition is something very different - they would ride thin air to move less weight around. But all the mortals (pun intended) suddenly needing CF fork on alu frame...beyond my understanding.

    that cannondale compression plug is part of their SI system. Shockingly bad and totally inadequate in my opinion.
    i have had 2 sets of cannondale forks fail on 2 different bikes, cannondale used to use a star nut intended for steel steerer tubes in carbon steerer tube forks (both bikes were circa 2006/7) cannondale customer service was awful, they said it failed because it was over tightened and didnt warranty them.
    i dont know how long cannondale did this for, do anyone remember this, i did quick google search and people have commented about this in forums. i still have a cannondale slice of that era, when i get round to it i will dismantle it to see if that one used a star nut inside.
    i had another carbon steerer fork fail (not cannondale), it was super light and pretty expensive, it failed near the tube/fork leg junction. it happened when i was sprinting, the fork lost its structural integrity. i didnt crash but knew something was wrong, when disassembled the fork steerer was still attached but it was "wobbly", on closer inspection i noticed the steerer tube material was thinner (thickness of material not diameter) than other steerer tubes i compared it to, it was light for a reason, they use less material.

      This one is currently my favourite. It's pretty long, smooth, and it comes in different diameters to fit the fork steerer. Most fork steerers are 23 mm internal diameter, but some have thinner walls and the expander needs to be 24 mm, and some cheaper forks have really thick-walled steerers and you need 22 mm.

    What I always did was torque the stem bolts just to where your riding motion won't move the handlebars but a crash can easily rotate the stem and steerer. If you have your steerer and stem so tight together any impact will directly go to the joint area. By allowing the stem to rotate when a large impact happens, you can potentially save the steerer.

    6. Voids never cause a fork fail only these stupid shallow plugs do. Nobody has a pic of a carbon steerer fork that failed that used a 100mm plug Andy's went way below the bottom stem bolt 'crimp zone' and was torqued proper with a torque wrench.
    7. The 11000 forks recalled by Cannondale recently had alloy steerers. It was an issue with the lawyer tabs if the skewer was loose and a heavy rider grabbed front brake hard.

Similarly, while carbon bikes cost more and thus make pricier repair jobs still be economical, they will still generally outperform alloyed bikes, which is the reason people ride them in the first place.
