  3. Helmet Weight

    in Trials Gear

    Posted

    Oh dear. I should have known I would offend someone. But it's not rare for me to offend someone, so please don't be offended that I have offended you. :rolleyes:

     

     

    I wouldnt worry about it,Guys isnt that easily offended, unlike halfshaft !

    Indeed, not offended at all, that's why I added the  :xmas:
     
    I am very proud though, about the success of Jitsie. The owner of Jitsie is a member of our club and his father is the chairman of our club.

  4. Helmet Weight

    Following a couple of mentions of Jitsie, I just went and looked on their website. The HT1 weighs 1100g. They don't quote a weight for the HT2, but it is "designed in Belgium" :rotfl: .

     

    Airoh quote "from 900g" for the TRR but as everyone quote their weights as +/- 50g I imagine 950g would be a better figure for comparison.

    Ahum! And what's so funny about that!?  :angry:

    By the way I love my Airoh TRR, it's light AND very comfortable. But it ain't cheap.
    And I've got Smith Fuel MX goggles, that fit nicely over my glasses for the longer rides.
    As you can see in my profile picture I used to ride with a "road" jet helmet, on which I mounted a trials visor, but in hindsight it was way too hot under it.
    Concerning the weight reduction: every bit helps and will be noticed i.m.o.

  18. Trials Bike Evolution - Where Next?

    Air suspension, like on mountain bikes or as the Fox shock (for Montesa)
    Very light and adjustable.
     
    Ceramic (wheel) bearings (already available) Less wear, better resistant to pollution.
    Ceramic coating of cylinder / piston: Less cooling necessary = less weight.
     
    And they could use the weight savings to strenghten the frames of some bikes.

     

  22. At What Point Do You Replace Your Chain And Sprockets?

    in General Trials Talk

    A picture of your worn front sprocket would be helpful.

     

    I also use 2 chains ( is a more common practice on mountain bikes) so the sprockets last longer.

     

    Most chain wear on trials bikes comes from dirt and/or lack of lubrication. A 520 chain can take much more power than our trial bikes can produce. (top riders with their high peak loads excluded maybe)

     

    I replace everything when I can almost see a complete tooth, when I pull on the chain at the rear of the rear sprocket.


     

    I don't want to run the risk of a broken chain punching a hole in my engine casing.

    ( fwiw: a worn chain isn't stretched, it means that the pivot pins and bushings are worn, and worn pins break easier)


     

    If possible use a 10T front sprocket. Chains don't like to take sharp bends and it reduces wear a little bit.
