  • You weren't far off the £1,100 for the Fixie Inc Peacemaker, which is a lot of very nice bike: http://www.cycles-for-heroes.com/bikes/singlespeed-fixed-gear/peacemaker

    But meh, if it rides lovely and you enjoy it then seriously don't let the price haunt you. There's not one of us that hasn't bought something that wasn't the best deal at times, the important thing after that is just whether you get the value out of it by using it. The lesser spec'd components can be replaced over time if they bug you. Belt drive remains nice.

  • That bike is still in production (Fixie Peacemaker)?! - Seen it on youtube but think the vid was back in 2010 and the company I got my bike from told me they since went bankrupt (cheeky sods). Cheers for the advice Vinylvillan and Velocio - its my first fixie and yes it does make me smile (although I'm beginning to find out the specs are duff but noted it uses the same type of steel as the peacemaker double butted cromolly 4130 or whatever). As for wether I get value out of it - thats not an option mate. At that price I have to use it. Got a racer I could revert back to if fixed gear becomes a problem but may just sell the components to cover the cost of this project.

  • If you take into account the extra cost of the belt drive, the rest of teh parts are decent enough and of a similar quality to most 500 quid OTP fixed gears.

    They are not shit parts, but parts chosen for aesthetics first. The hubs are good, i have put many miles on Andel cranks with no probs, and the rest is all ok

  • Cheers mate, I'll sleep a bit better this eve now... Until my other half finds the receipt?! Lol...

  • Belts are for trousers.

  • And fans on cars.

  • Or boxing awards

  • Or conveying things from one place to another

  • Or asteroids

  • Or car seats for safety

  • Looked at the District too but the model I wanted (2009) was sold out and since then they're hard to come by - think they had a mass product recall... Evans used to sell them. Plus the 2010 and later models had a price of c£900... Admittedly i don't know as much about frames as the guys on here so the advice is appreciated but I researched consumer (i.e. affordable) belt drives for some time and Schindlehauer for me looked by far the best (but too pricey) then the Trek until it disappeared of the face of the earth. The revised Trek models I didn't like the look of and as already mentioned seemed to get recalled... The £800 I paid is pricey but I never would have been competent enough to build my own. Fixie Inc made a nice belt drive Peacemaker but again that disappeared too.

    District recalled:
    http://velonews.competitor.com/2011/10/bikes-and-tech/trek-recalls-fx-and-district-bicycles_196461

    The District was (as proven by your link) recalled because of a defective seat clamp bolt. It should have been recalled because it was flexy as fuck. Not good for frewheel belt use and would almost certainly have been hopeless fixed. The bb was pretty low too.

  • Phew.. So I can rule that out too only the Peacemaker and Schindlehauer would have been left as expensive options. Guess the best thing to do would have been to build one myself (if I could).

  • hi, I'm new to the community. And i have a question.

    where can i buy this?

    Thanks!!

    Phil Wood belt pulleys can be ordered from Hubjub. (Not listed, but available as special orders... http://www.hubjub.co.uk/philwood/philwood.htm)

    They are expensive.

    And very heavy.

    But there are very few other options for custom belt pulleys.

    Also, you need to make sure, when changing belt gearing, that the combination of pulleys and belt length is within range of adjustment of your dropouts. There's a calculator thingy on the Gates website.

  • Gates have fixed thread-on cogs now with the center-track system: http://www.universalcycles.com/shopping/product_details.php?id=47338&category=4081

  • As soon as someone shows up at a track race with a belt and lower roller system the UCI will ban it. If not before.

  • Probably, I wonder what grounds it would be on.

  • I cant see it being quicker. All the datat I saw before geting mine, showed it to have the same efficiencey as a chain. Untill the chain started to need lube, or became dirty. Then the belt wins.

    But who turns up for a race, with a dirty dry chain?

  • Probably, I wonder what grounds it would be on.

    "We're the UCI and we're cunts"?

  • Heh.

  • Chain tension for a track sprinter putting out 2000W at 100rpm on 50/13, i.e. accelerating through 30mph, is about 420lbf. That drops to just under 400lbf if you use the slightly bigger 69t Gates pulley. Starting load for Kilo riders is a lot more than that,not sure how much more but easily double. Presumably the Gates Carbon Drive needs a preload not far off half the maximum drive tension, so that the slack on the bottom run doesn't get big enough to let it jump over the teeth, but the efficiency under load can never get better than whatever it is with zero tension on the bottom run, so it's reasonable to assume that the actual in service efficiency can be modelled without having to apply actual service input torque by setting the preload to half the in-service top-run tension in which you're interested.

    Friction"Facts", by the way, are noted snake-oil salesmen; they strip the packaging grease off new chains and sell them for double the original price based on spurious no-load 'friction' tests which are no such thing, they are tests of lubricant viscous drag between grease and oil. While this does exist, it becomes pretty trivial under the low-speed/high-load conditions found anywhere on a bicycle.

  • So has the landscape changed on belt drive yet?

    The biggest problem I've found is simply the lack of retailers in the UK to sell the full range of components and accessories, and to have them in stock.

    Does anyone know of a retailer in the UK that is selling everything online and holds a stock for most of the popular belt drive systems, including the newer Gates stuff?

  • Mine jumps when I really give it some beans on a SS climb. Might upgrade to the new style.

    ....or maybe I should see if cleaning the bike helps.

    that is pretty bad...
