Giant Rear Axle


New Member
Hi, I’m looking at purchasing a tailfin aeropack for my Giant Fastroad Advanced1. I need to use tail fins rear axle and are given options;
12-142mm axle with a
1.0mm pitch
1.5mm pitch
1.75mm pitch
Can anyone tell me which axle-pitch I’ll require?

"Combining the superlight T1 carbon rack with the lightest pannier bags in the Tailfin range, the SL Package is designed for those who want to ride fast. The SL pannier bag features High-Frequency welded seams and a roll-top design, making it the perfect option for riders who want complete protection from the elements without compromising on weight. Seamlessly compatible with nearly any road, touring, hybrid or commuter bike, the SL Package is the ultimate lightweight solution for carrying luggage by bike, as equally at home on the weekday commute as it is on fast touring escapes.

Giant Scott DeVinci (some)
BH Orbea Bianchi
Cipollini Fuji Raleigh
Kinesis Salsa Masi

Would be useful to amend thread title to 'Tailfin . . .' rather than 'Giant . . . '.
