Davetrials Posted February 13, 2006 Author Report Share Posted February 13, 2006 26"and 24" Quote Link to comment Share on other sites More sharing options...
narrowbars Posted February 13, 2006 Report Share Posted February 13, 2006 26"and 24"On 26 I think it's about 12 inches Quote Link to comment Share on other sites More sharing options...
F-Stop Junkie Posted February 13, 2006 Report Share Posted February 13, 2006 Zero drop means that it's in line with the axles and does not drop below that point. That'd make it 13" on a stock, 12" on a 24". Quote Link to comment Share on other sites More sharing options...
Tomm Posted February 13, 2006 Report Share Posted February 13, 2006 Yeah, except wheels are usually slightly bigger than they say, so a 26" wheel is probably closer to 27" or something, which would make the rise 13.5" Quote Link to comment Share on other sites More sharing options...
Janson Posted February 13, 2006 Report Share Posted February 13, 2006 335mm on a coustellier (zero drop) with maxxis 2.5 and 2.35 tyres.13.19"... Quote Link to comment Share on other sites More sharing options...
spunkey_monkey_boy Posted February 13, 2006 Report Share Posted February 13, 2006 yeah its all going to depend on tyre choice, whether the bike is loaded or not (has someone on it) and stuff like that... Quote Link to comment Share on other sites More sharing options...
ScotchDave Posted February 13, 2006 Report Share Posted February 13, 2006 Factors to consider are: fork length, headset depth (bottom cup only), wheel total radius (including tyres on both wheels). These all affect BB height. Quote Link to comment Share on other sites More sharing options...
Mark W Posted February 13, 2006 Report Share Posted February 13, 2006 Yes, but if it's zero drop BB, then all that stuff doesn't matter, does it? 'cos we know what the eventual BB rise/drop is, which is 0mm, so it's just the measurement of the radius of a wheel, basically? So if that was guesstimated as between 13-14", that means - in mm as Dave asked for - a range of 325mm - 350mm, basically. Quote Link to comment Share on other sites More sharing options...
Janson Posted February 13, 2006 Report Share Posted February 13, 2006 it's not hard to either measure up or shut up. Quote Link to comment Share on other sites More sharing options...

Suddenly the frame has bb drop. Quote Link to comment Share on other sites More sharing options...

ScotchDave Posted February 13, 2006 Report Share Posted February 13, 2006 Yeah but to give that measurement we need to know the exact radius of his rear wheel. Which depends on rim and tyre. Quote Link to comment Share on other sites More sharing options...

Suddenly the frame has bb drop. Yes, but we know this bike has 0mm BB drop. That's the whole point. With the setup, it is 0mm, which is what Dave wants to know the measurement for...
