J Trials 31 Posted August 31, 2008 Author Report Share Posted August 31, 2008 which one? Quote Link to comment Share on other sites More sharing options...
Mark W Posted August 31, 2008 Report Share Posted August 31, 2008 They don't. I doubt you'll be able to find many with a decent range, simply because the flanges would have to be super close together to make it work. You could always buy a White Industries Eno freewheel with the two sets of teeth (16t and 18t, I think), but then you're limited to running something like a 22t or 20t sprocket up front.

J Trials 31 Posted September 1, 2008 Author Report Share Posted September 1, 2008 Since I don't really like stock bikes, I was thinking of building up a Megamo dual disc mod with gears, but there's the problem of the hub and derailluer hanger. So, I guess I will get a 24". Possibly a streety stock. Quote Link to comment Share on other sites More sharing options...
JonMack Posted September 1, 2008 Report Share Posted September 1, 2008 Why do you need gears?There's a reason almost everyone has gone singlespeed these days... Quote Link to comment Share on other sites More sharing options...
J Trials 31 Posted September 1, 2008 Author Report Share Posted September 1, 2008 Why do you need gears?There's a reason almost everyone has gone singlespeed these days...Yeah, I have a singlespeed mod. I live in town and it's real hard to get around when the only bike you have is a singlespeed mod with 18-12 gearing. Would like to have a bike to ride around town and still be able to ride trials on it when I have to or want to for that matter. Quote Link to comment Share on other sites More sharing options...
Mark W Posted September 1, 2008 Report Share Posted September 1, 2008 Even if you managed to find a mod hub that could take a cassette, how would that benefit you? The typical (and best ) mod ratio is 18:12, so if you got a cassette apart from maybe getting an 11t sprocket to fit, you're going to be running sprockets larger than 12t, which will make the gearing lighter and therefore worse for getting around? If you wanted to make it slightly easier to get around you'd want to be getting gears up front, but even that would be shit.You'd honestly be better off not compromising the strength/weight of your bike purely to make it fractionally easier to ride around. I've ridden a good few miles on my mod, and it's not ideal, but at the same time I'd rather have it so my bike was better for riding trials on than for riding to places to ride trials, if you get me? It's never going to be good for getting around, and gears aren't going to make a massive difference. Putting 10psi more in each tyre would probably be better.

J Trials 31 Posted September 1, 2008 Author Report Share Posted September 1, 2008 Yeah, I get what you mean. I wouldn't do it to my bike anyway. I'd get a different one to experiment, but that's beside the point. I'm kind of new to the whole gear thing anyway. I've always had singlespeed bikes. Whether it be trials or BMX. But I do have another question. Smaller sprockets are higher gears? How can that be? More teeth means a higher gear right? It kind of makes no sense.

Revolver Posted September 1, 2008 Report Share Posted September 1, 2008 18:12 = 1.518:11 (smaller at the back) = 1.6It's maths. Larger first number/ Smaller last number = more wheel revolutions per pedal stroke - a harder gear. Smaller first number (and therefore chainring) / Larger last number (and therefore rear sprocket) = less revolutions per pedal stroke - a lighter gear.Don't do it, no mod has a hanger.

Jason222 Posted September 1, 2008 Report Share Posted September 1, 2008 Don't do it, no mod has a hanger.Simtra made a prototype frame with verticle dropouts and a hanger! Havent heard anything of it in a long time! Quote Link to comment Share on other sites More sharing options...
J Trials 31 Posted September 1, 2008 Author Report Share Posted September 1, 2008 Like I said. I've changed my mind. I'm going for a streety 24" or 26". Quote Link to comment Share on other sites More sharing options...
PaRtZ Posted September 1, 2008 Report Share Posted September 1, 2008 Rohloff anyone?New design with an astonishing 14 gears! Quote Link to comment Share on other sites More sharing options...
Muel Posted September 1, 2008 Report Share Posted September 1, 2008 Imagine the weight of that! I see no disc mount though. If you want a bike to get around on, road bikes can be found for next to nothing these days, and would be a much better commuter than a Megamo.

Greetings Posted September 1, 2008 Report Share Posted September 1, 2008 Yeah, I have a singlespeed mod. I live in town and it's real hard to get around when the only bike you have is a singlespeed mod with 18-12 gearing. Would like to have a bike to ride around town and still be able to ride trials on it when I have to or want to for that matter.Sounds like you just need a 24". Get a Fourplay or something similar, it'll be a great street toy. Quote Link to comment Share on other sites More sharing options...

J Trials 31 Posted September 2, 2008 Author Report Share Posted September 2, 2008 Wouldn't it be sick if somebody made a 3 speed internal hub for trials? Some road bikes have a 3 speed internal hub and they are so nice. Quote Link to comment Share on other sites More sharing options...

Muel Posted September 2, 2008 Report Share Posted September 2, 2008 I dare say it would be totally rubbish, you only ever use one gear ratio for trials, and trials bikes are the worst bikes ever for riding anywhere, so instead of spending good money making your bike have gears, get a cheap bike that already has gears, and a whole lot more that makes it good for commuting.

Mark W Posted September 2, 2008 Report Share Posted September 2, 2008 There's virtually no point at all for gears in trials.EDIT: Basically, what Muel said, and what I said earlier in the thread. Quote Link to comment Share on other sites More sharing options...
eskimo Posted September 2, 2008 Report Share Posted September 2, 2008 (edited) There's that one. I dunno if it can take 1/8th chains though. As 3/32th gets used in racing mainly i believe. The problem being with carrying a bmx wheel about would be the chain length. I actually don't think there's a solution to it other than go stock or pump them tyres up.[edit]Disc mount?Whoops Edited September 2, 2008 by eskimo Quote Link to comment Share on other sites More sharing options...
Mark W Posted September 2, 2008 Report Share Posted September 2, 2008 The most obvious problem with that hub is the size of the rings on there. From what I could see, the smallest ring on that is over 14t, so if you wanted to keep the standard 1:1.5 mod ratio, you'd need to run a 22t sprocket, minimum. With modern frames, I don't even know if you could really get away with that and run a bashplate, as it'd stick down past the majority of them. I don't even know how well it'd clear the frame anyway... Quote Link to comment Share on other sites More sharing options...
Fixed Pants™ Posted September 2, 2008 Report Share Posted September 2, 2008 Leeson 505 with stock spacing anyone? Probably get a hanger on that too. Quote Link to comment Share on other sites More sharing options...
