Bstmn Posted September 21, 2016 Report Share Posted September 21, 2016 Hello. I was wondering if someone can help me out. I've never ridden a trials bike but I'm looking to use one as a commuter (the idea of riding a bike without a seat is why). Is it possible to run a large gear than one normally would on the front chainring? Most of trials bike I've seen (I'm looking at a street trials bike) have a 18 tooth chainring. Can something much larger than that (like those you find in regular road or MTB bike) be installed on trials frames? Quote Link to comment Share on other sites More sharing options...
adamant Posted September 21, 2016 Report Share Posted September 21, 2016 You could yes but it would defeat the object of having a trials bike really as you need the lower gearing to help do moves Quote Link to comment Share on other sites More sharing options...
Alex Dark Posted September 21, 2016 Report Share Posted September 21, 2016 It all depends on the bb yoke clearance , Bb length and offset of the cranks. On certain frames im sure it would work. Quote Link to comment Share on other sites More sharing options...
isitafox Posted September 21, 2016 Report Share Posted September 21, 2016 Just out of interest, why do you want a bike without a seat for commuting? Quote Link to comment Share on other sites More sharing options...
Ross McArthur Posted September 21, 2016 Report Share Posted September 21, 2016 @monkeyseemonkeydo rode from John'O'groats to Lands End on a trials bike. Anything is possible. 2 Quote Link to comment Share on other sites More sharing options...

Anything is possible. That wasn't a trials bike in the modern way of things though!! It was an Orange Zero with a 450mm (I think) seatpost and about 5 gears. To be fair it wasn't a very good idea! 3 Quote Link to comment Share on other sites More sharing options...

Long story short, to get a better workout. They have bikes designed for that purpose (elliptical type stand-up bikes) but they're heavy and awkward. I have one and looking to find an alternative . 17 hours ago, Alex Dark said: It all depends on the bb yoke clearance , Bb length and offset of the cranks. On certain frames im sure it would work. Is the bb yoke clearance how much the chainstays skew outside immediately close to where the BB is? Any bikes that might work with a large chainring? All the ones I've seen look like it might be a problem accepting a large chainring. Quote Link to comment Share on other sites More sharing options...

isitafox Posted September 22, 2016 Report Share Posted September 22, 2016 If you need to resist the urge to sit just take the seat off your regular bike. Your back will suffer if you use a seatless bike for pedalling long distances. Quote Link to comment Share on other sites More sharing options...
gage-mann Posted September 22, 2016 Report Share Posted September 22, 2016 Just single speed a mountain bike so that's it's half hard to pedal. You'll be stood up more often then with setting off and hills, best way to see physical strength and endurance fast over a couple of months.

weebryan Posted September 23, 2016 Report Share Posted September 23, 2016 Why don't you try and get an older frame that has a gear hanger and put a road mech and cassette like we used to before single speed came out best of both worlds 2 Quote Link to comment Share on other sites More sharing options...
AndyT Posted September 23, 2016 Report Share Posted September 23, 2016 (edited) On a real trials bike ( 5 working gears, seat, 1999 geometry) you can no problem. on today's frames (I wouldn't call them bikes, as they can't be ridden as a bicycle should be ) you would look very very strange and probably fall a lot. Especially if you try to turn at high speeds. Highs speeds being anything over a walking pace. insert Volvo cannondale libor karas picture Edited September 23, 2016 by AndyT 1 Quote Link to comment Share on other sites More sharing options...
Scott Gibbs Posted September 24, 2016 Report Share Posted September 24, 2016 Not mine but o found that on google, Onza T-Rex with what looks to be a 44t chainring. Quote Link to comment Share on other sites More sharing options...
Bstmn Posted September 25, 2016 Author Report Share Posted September 25, 2016 thanks for suggestions. I was planning on adjusting the height of the handlebars the make things easier on my back. Anyway, obviously, I'm just thinking things through at this stage. It was just an idea that came to mind and thought I'd come here to ask about it. Appreciate the feedback though! 16 hours ago, Scott Gibbs said: Not mine but o found that on google, Onza T-Rex with what looks to be a 44t chainring. Thanks for finding this!
