BT RAVen5.0 sizes and what to buy?

[Sondre]

Hi, I'm gonna change back to a bt 5.0 again.. Feel like my px is holding me back on some cases http://www.trials-forum.co.uk/forum/style_emoticons/default/sad.gif

Anyway, I use a BTBike 06 crank with a 18 thooth ENO / ACS. My bb on the tibo is 68-118, is this wide enough? Or do I have to buy another one, in this case 68-128...

If I'll have to buy 68-128, which one would you buy?

Thanks

You should search about this as Rav answered this question a few times already for RAVen6.0. I think the same should more or less apply to the 5.0
