dave33 Posted September 2, 2013 Report Share Posted September 2, 2013 (edited) I'm not sure actually. A lot of trials is really psychological it seems. One rider does something which may well be placebo and everyone copies, it's just the way it is. No offence at all - people can do what they want, but the physics doesn't change. I will look forward to you kicking some arse next year with your 200mm cranks. I could ask him in Belgium I suppose. Like I thought, guessing again. Don't forget to explain physics to him Edited September 2, 2013 by dave33 Link to comment Share on other sites More sharing options...

monkeyseemonkeydo Posted September 2, 2013 Report Share Posted September 2, 2013 Why are you even getting involved ? Do you even ride ? ~15 years and counting, 20", 26" and 24", mainly for fun with a good few years competing mainly at local level but up to National thank you very much . 2 Link to comment Share on other sites More sharing options...

monkeyseemonkeydo Posted September 2, 2013 Report Share Posted September 2, 2013 depressive moods in a short form. I thought that might've been what you were getting at . Wow you sound amazing. Damn straight. I'm ok but the point is I've been around long enough to run everything from 158mm cranks on many a mod through to 175mm on 24s and stocks. That's irrelevant when deciding whether shorter cranks change your gearing though. Link to comment Share on other sites More sharing options...

Luke Rainbird Posted September 2, 2013 Report Share Posted September 2, 2013 How about just leaving the ego out of the thread, I'm not sure the forum has a high enough bandwidth allowance to fit it all in. The bike doesn't go any further if the gear ratio/tyres etc remain the same. The only thing that'll be any different what so ever is the distance your foot travels and the fact that you have less leverage. Neither of these are entirely negligible, else you wouldn't feel any difference when changing crank length and everyone would run short cranks for clearance and to save weight, but assuming the only variable is the crank length there's no way in hell that the bike itself will move a different amount per crank rotation. How anyone could possibly imagine otherwise is completely beyond me. Edit; Josh - 1 Link to comment Share on other sites More sharing options...

FamilyBiker Posted September 2, 2013 Report Share Posted September 2, 2013 (edited) to be honest i see a point in the foot making less travel with more force giving the feel of a shorter run up,as you have a certain "kick-travel" youre used to and working with,at least in the final punch.same movement in the foot with a bit more effort shoots you up steeper when closer to an object on a 165 than a 175 mm crank. but technically and physically(edit:due to the fact you have to put in more power to achieve the "same") thats not part of the gear ratio itself,i think thats what people are getting at here. but i see no point in posing,especially for a well known rider that should keep his image neutral,sorry Edited September 2, 2013 by FamilyBiker Link to comment Share on other sites More sharing options...
dave33 Posted September 2, 2013 Report Share Posted September 2, 2013 I actually love how twisted every one is on here, ego lol I never ever come on here and said I'm better than any one. Until today Also love how your trying to twist things into me saying shorter cranks give you more rotations. If some one wants to point that out carry on. All iv said is on a half rotation with a shorter crank you can start closer. As you foot moves less Just to make it clear I'm right footed, half pedal starting left food can start closer. Maybe you should go try it for your self Link to comment Share on other sites More sharing options...

Luke Rainbird Posted September 2, 2013 Report Share Posted September 2, 2013 Let's break this down a little shall we. 1. I actually love how twisted every one is on here, ego lol I never ever come on here and said I'm better than any one. Until today 2. Also love how your trying to twist things into me saying shorter cranks give you more rotations. If some one wants to point that out carry on. 3. All iv said is on a half rotation with a shorter crank you can start closer. As you foot moves less 4. Just to make it clear I'm right footed, half pedal starting left food can start closer. Maybe you should go try it for your self 1. Whether you've said it before or not, you've put across fairly clearly in this thread that you think you're superior to everyone else in terms of both riding and intelligence. So yeah, ego. 2. I'm twisting nothing, I'm simply stating facts. Other than changing either sprocket the gear ratio remains constant. Assuming that overall wheel diameter (and therefore circumference) remains constant too then it holds that bike travel remains constant as well. 3. If you're talking about crank/obstacle clearance then this may be the case, but it sure as hell won't change how far you travel on the bike when rolling. Unless of course you just don't rotate the cranks so far (in terms of rotation angle) in which case this is no different to using a longer crank and doing the same. 4. Just in case you're going to try and build another tangential argument, switching feet won't change anything either. I'm not sure if it's just a case that you're incapable of putting yourself across clearly and concisely, perhaps, but whatever the cause you come across like a completely arrogant arse in 99% of your posts on here.In before: "You too", "takes one to know one" or similar Link to comment Share on other sites More sharing options...
bing Posted September 2, 2013 Report Share Posted September 2, 2013 Let's break this down a little shall we. Other than changing either sprocket the gear ratio remains constant. Shortened it a bit. This is all it is about. The length of the lever doing the work does not adjust the gear ratio. All it alters is the effort required to make the gear ratio work for that particular person. Like this guy, me, and Adam, plus various others have said, the ONLY way to physically alter a gear ratio is to change one of the actual gears. Basic physics, simple as that. Ps.
