wattage and gradient simulation seems similar, just see which once is cheaper and whether cassette is included or not. and whether need to buy adaptor if using disc brake bikes with thru axle. if using roadbike with qr no need worry.

my old cycleops hammer came with adaptors for multiple wheel axles so can change to disc brakes and boost hub mtb bikes if needed, but needed to buy cassette. and never got anywhere near the 2000w limit lol.

This is why i like rudy other than the part the clip will smear then rx clip lens.

I've given up on Oakleys long time ago. The lenses peel off very easily.   
I'm wearing NOS Rudy Project Ryzer and Traylyx. 
I have some NOS BBB which are also nice to wear.

Got mine from reliance optical bangsar.

I did mind in the glasses shop near the escalator in ground floor of Amcorp Mall. I think the shop name is called Tanjong Optical.

Previously i bought it online (based overseas prior) but the clip insert i went to my usual optical to make it. That time rudy is not tat big in Malaysia yet.
