These are the smallest I found that would fit on my small frame Specialized hybrid. The vertical post (the seat post bar I guess) bottle holder is too close to the top bar and these were the only size where I could get the bottle in and out. My main 22 Oz bottle fits in the other holder, so as a supplement this works. They're only 500ml / 16.9 Oz so not great for long rides or hot days, but it's something if you don't go with the side holder suggestions. https://www.amazon.com/dp/B084GNMZ27?ref_=ppx_hzod_title_mob_b_fed_asin_title_0_0 [ETA: reposted after the shortlink version got removed]
