I picked up these on Ebay recently and they work pretty good. Also, I can still use the original position, Not sure if I would want to switch to forwards on a Bonnie for good. https://www.ebay.com/itm/1346750296...wB8T6X4awAH/JK3AiX7YV/vYm9|tkp:Bk9SR-qFyffnYg
Sorry bud but I am not clicking on that link without you giving some sort of intro and a picture of what you're talking about, and would suggest others are cautious before considering it @Havit do you have the ability to check links?
I also ended up picking up a Corbin, and that gave me a extra inch of leg room as well, so that's also a good solution to relax the knee angle.
