Description
Gebla Rohbox ShimKit A21A modification kit that allows you to use Shimano Hydraulic drop bar shifters to operate the Rohloff Speed Hub. The Gebla Shimkit is a unique and creative way to modify drop bar Shimano Road or gravel shifters to operate a Rohloff internal geared hub. Previous versions of the Gebla only worked with Sram Double tap shifters, so enabling Shimano compatibility is a huge win. It creates by far the neatest way to run a Rohloff Hub and drop handlebars.

Chewer was indifferent
Size: 1 Count (Pack of 1)
At first, the two ears I bought were mainly ignored. Now I am seeing teething marks. Took about 2 months for my chewer to stop chewing my wood fence and on these.

great chew!
Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
Our dog is a BIG fan of PetQwerks so when we saw this bacon dog chew, we had to try it out! Chews are amazing for hyperactive dogs, dogs with separation anxiety, etc. They keep dogs out of trouble and is great for dental hygiene! Our dog doesn't enjoy getting his teeth cleaned with a toothbrush so we give him lots of chew toys. When we opened up our amazon box, our dog was being so nosy and immediately took to the bone! Awesome chew and we love PetQwerks!

Best soothing chew toy for puppies yet!
Fantastic products!! Got these for my son’s 10 wk old chocolate lab puppy. He immediately started chewing on one and continued for close to an hour. I wish I had tried these with each of my own labs when they were pups (we’ve had 5 over the past 20 years). Inexpensive and an easy way to keep a determined chewer occupied without food/treats. I highly recommend for a heavy chewing breed like Labradors!!
