Hi their, as seems to be often the case I am quiet new to this so not sure about terms and sizes when it comes to changing things on my bike so a little help is greatly appreciated. I own a 2013 Carrera Vulcan and am after changing the front crank to a single ring (chain guide needed). Could you possibly point me in the right direction with what I should be looking for, sizes I need and what to avoid. Thanks for your time. :D

    Stock crank is a Shimano square taper, you need a square taper crank that needs the same width BB (nearly all MTB Shimano will be fine) and has removeable rings.

    I'd look on ebay

    I notice the example you gave is x3 so I assume I can take 2 of the rings off creating the x1 I'm after ? Might sound obvious but would that leave me needing spacers or will the chain guide take up the slack ?

    You put a single ring in the middle location, you shorten the chain to suite, if you use a narrow wide (or similar) ring there will probably be no need for a chain guide (which can't take up any slack, not sure how you think it would). You can use the original rings but ramped teeth (for shifting) are not the best idea when you want the chain to stay on.

    Yep, all seems quiet obvious when explained like that ! Thanx for the assistance, will be ordering the parts this weekend. Looking forward to getting stuck-in, cheers.
