Fork tube question. Extended tubes for a 550
« on: August 07, 2018, 01:49:28 PM »
Anyone sitting n a set of extended tubes for a 550?
What other shop besides Franks selling them?
Seen there was a way to use 750 tubes in 550 lowers would anyone have anymore info on this.
Looking for +4 tubes but +6 would work too.

What are the differences between 750 and 550 fork tubes?  If compatible, go with Cycle X. http://www.cyclexchange.net/fork_tubes_and_accessories.htm

So are you saying the main difference between the 500 / 550 axle and the 750 axle is just length?
If that is the case I will just get a complete set of 750 tubes Source a used set of lowers and get a new set of extended tubes.
