Not sure about on a Hammer but I have them on my Jackpot. I don't see why they wouldn't work or be any difference from the jackpot. No issues with shifting or the brake lever. The angle you set them at is adjustable so you an put it where it's comfortable for you. you do have to purchase the splined adapters though. I've found that with the bottom part swung out that they are a tad too far out. I'm 5'11 with a 32" inseam fwiw. I've found them more comfortable and useful in the down position basically using them as just mini floorboards.
