Gear Ratios

[jwcw]

Hi

I recently purchased an Onza Zoot 2010 with out really thinking about it as i wanted to get into trials and i also wanted to ride about 2 miles to university on it each day. Im not very savvy on bikes and i understood the gear ratios on trials bikes is low, but i did not realise it would be this low. I struggle to ride it over a mile without being very tired. Is there a way to change the sprocket and gear ratio so i can still do trials but also ride around 2 miles a day easily. If this would be possible and i could still do trials on the bikes i would appreciate if anyone could point me in the right direction of what i need to buy.

Thanks

You can change the rear sporockt to make it harder, What ratio are you currently running (count the teeth on the freewheel and the sprocket)

Ok im running a 18-14 gear ratio according to tarty bikes where i purchased the bike. Would i have to change both sprockets and buy a new chain i presume?

This is the bike i have by the way http://www.tartybikes.co.uk/24_inch_trials_bikes/onza_zoot_2010/c50p11230.html

Just the rear, you wont need to change the chain, just shorten it. you could try 18-13, any harder you may struggle to get on with trialsy stuff.

You don't need a new chain your current one is fine, as the zoot has horizontal dropouts you'll need to tension the chain properly when you get a new rear sprocket, only a rear sprocket is need, maybe look at a 13t it will be alot easier to pedal your journey and you can still ride trials although maybe not for power moves more flowy bmx moves but it is do-able.

Would something like this in either 12t or 13t work http://www.tartybikes.co.uk/screw_on_sprockets/echo_tr_screw_on/c73p10709.html I presume it would then become a lot easier for me to pedal as i would pedal less.

Thanks for the help.

Yeh it would, you just need to know how to take the sprocket off.
