I've been using some of the SiS products for a while now so I thought I'd share my thoughts on them starting with the GO range, the ones I use on the bike. I'm aware this is a positive review - that's because I think these products are good. I'll review the REGO range and Supplements in later videos.
If you find this useful, please click a few of the advert links, it really does help. Thank you!
This is the third video I've made as a member of the SiS Winter Academy, so please check out Video 1 and Video 2 as well.
