ALI_GH Posted February 28, 2014 Report Share Posted February 28, 2014 hi i have bought a giant stp ss 2011 recently to ride street-trials but the gear ratio is really really anoying . specially when doing trials moves crank : 28 t rear sprocke : 12 t i wanted to change crank to trial crank but my friend said you must change the chain to trial too and it wont work with your rear sprocke . im confused what i should do .. is it possible to change the rear sprocke too ?

dezmtber Posted February 28, 2014 Report Share Posted February 28, 2014 Normaly a 26" trial bike uses a 18x15 gearing, your probably better buying a longer chain and fitting a larger tear spocket 1 Quote Link to comment Share on other sites More sharing options...

fruitbat Posted February 28, 2014 Report Share Posted February 28, 2014 What type of fitting on the rear sprocket is it, screw on or slide on with splines? Should should be able to get a bigger sprocket for the rear and a front with a ratio to match (I use 22 front 19 rear, old school ratio but have always used that and it works for me) 1 Quote Link to comment Share on other sites More sharing options...
dezmtber Posted February 28, 2014 Report Share Posted February 28, 2014 those giant hubs are these as standard. you can unscrew the lock ring and fit any shimano cassette spocket to it. i would use a halo fat foot cog u would need a 23t cog thou.surely do a 22T cog http://www.ison-distribution.com/english/product.php?part=CSSUS13 1 Quote Link to comment Share on other sites More sharing options...

goanywhere Posted March 25, 2014 Report Share Posted March 25, 2014 Also you might want some rigid forks, to lower the front end for rear wheel stuff. And they weigh a ton! 1 Quote Link to comment Share on other sites More sharing options...
dezmtber Posted March 25, 2014 Report Share Posted March 25, 2014 You will need a new chain, the new gears will need a longer chain may as well get yourself a kmc 610 or kmc kool while your replacing it then you'll have a good relable chain too. second that n the forks some tall alloy trial forks like inspired elements. Or trialtech ones would make it better for tgs or pure trials, thou if you are planning a more street style you may be better looking into some light sus forks, if you like front suspension on you trial bike 1 Quote Link to comment Share on other sites More sharing options...
