I assume this is for the Garneau?..in which case it is English thread...68 shell. The length is fairly easy to figure without taking it out. 105 triple? Prolly a 116 but as Op said..the sure way is to measure the spindle length after removing the cranks.
edit. Why did I think you had a Garneau? Check ****manos website for the appropriate length for yer crank model if you dont want to remove it first.
