Anyone know if Profile Design extensions are interchangeable?
 

I currently have profile design aerolite aerobars on my trek equinox. I dont like the L shape and would prefer an S shape like the t2. I'm wondering if I can just pull out the extensions and put in t2 extensions rather than changing out the whole setup. Anyone know? I know the OD of the t2 is 22.2mm, but not sure on the Aerolites.
