Centre sprocket

[scotty110788]

I'm not clued up on bike limbo so bare with me, this is 2nd bike I've got which has option for 3 gear on centre sprocket but theres only 2 cogs, does this mean i can upgrade from 18 speed to 27? or do they just use same gear changers on handlebars to save money for production, i have cboard hybrid comp and its on its way to a total customization

yes they do use the same gear changers to save costs and yes you can put an extra chain ring on the crank

oh cool, i have cycle plan with halfords so they can fit it for me is there anything i needa look out for when buying, and will it only be crank i have to change or will i need to change chain and that as well. Thanks for help

Might need to have a new bottom bracket that has longer spindles to fit the wider triple chainring.

Don`t boardmans come with compact chain rings anyway?

I am pretty sure they do so you will have a wide spread of gears anyway, adding another chainring is only going to give you a slightly lower and slightly higher gear and lead to a lot of gear multiplication with gears that give the same effective ratio from different front/ rear combinations.

Not worth doing in my opinion for the marginal gains you are going to get compared to how much halfords will charge you , i would put money on the cycle plan not covering you for modifying the bike as well so you would be paying labour as well.

sounds like its not worth it then, prob put my money somewhere else on bike and Halfords cycle plan means all manual labour for free, had my last bike in constantly after crash, they wer sick of my face lol

I think it would be free for repairs/maintenance but i doubt it would cover "modifications "
