Google isn't my friend on this search (wrong name sorted finally)

My old hack is fitted with a triple and fancy converting it to a single, the cranks are worn but I can make out truvelo (Wrong name truvativ) a nd blaze the bolt pattern is 4 bolt ! And 110mm across 74 to side

What BCD would that make I just wanted to make sure I order the right stuff :mrgreen:

My road bike is 110bcd and measures 110 looking at the wolf's chain ring guide mtb is different ?

Hope this isn't a stupid question the search did have any truvelo info #Help

    4 bolt just measure straight across! Almost certainly 104mm.

    Just to add the extra I needed the CCP2 crank puller by park tools to remove it :-) RaceTI 30T front sprocket went on nice screws only no new bolts required even better!

    Next step is 34-30 setup going to combat the hills OK ? looking at a sunrace 12-40 cassette for the 9 speed, OH I want DI2 for my MTB :-) #OverKill

    I presume you mean 11-40?

    I use 34:11-40 ten speed and that gets me up anything I want to climb.
