The new spero remains true to its original brief, but with some improvements: a threaded BB shell, neater cable routing, and a UDH compatible derailleur hanger for those who want to use SRAMs Transmission drivetrains.

In 2019, Áspero took the gravel world by storm, heralding a “new era of speed in gravel.” Fun, but flat out. The new Áspero remains true to its original brief, but with some improvements: a threaded BB shell, neater cable routing, and a UDH-compatible derailleur hanger for those who want to use SRAM’s Transmission drivetrains. And it’s more aero, of course. In the case of Áspero, aerodynamic performance is less about pure speed as a result of drag reduction, and more about conservation of energy. After a big day in a headwind, the three watts saved over the previous Aspero might add up to one less energy gel your stomach has to digest—WORTH IT.

In addition to the drag reduction, we also dropped the seat stays to give a bit more compliance out back, and reduced front-end stiffness slightly to make the last hours of a long race less painful. Between those dropped seat stays, we added in a bit more clearance for mud, too, taking what we learned from R5-CX (and the Unbound mudfest in 2023). It’s a lot of seemingly small improvements, but they add up to a lot. The result is a bike that feels a lot like the original Áspero, but is faster, more comfortable, and more versatile.

FEATURES:

  • Threaded Bottom Bracket: Aspero uses the asymmetrical T47a threaded bottom bracket we pioneered on R5-CX. It’s a simple, rider-serviceable interface that allows us to deliver the benefits of BBRight in a more user-friendly form. 
  • Universal Derailleur Hanger: We used SRAM’s Universal Derailleur Hanger (UDH) standard on the new Aspero. It’s ideal if you want to live your best ‘business in the front, party in the back’ life with one of SRAM’s Transmission drivetrains today, and ensures compatibility for future drivetrain developments.
  • Internal Cable Routing: Aspero shares the same bearing dimensions as R5, Soloist, R5-CX, and Caledonia, which means you can use any combination of bearing caps and stems. Want a super-racy, fully-internal look? Grab the ST31 and HB13 from R5.

Awesome bone for all dogs!
Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
My dogs LOVE this pig ear! It is very lightweight and easy for any dog, from my Great Dane to my Maltipoo, to carry and chew on. It has no odor, yet the dogs were interested immediately after smelling it. The pig ear is perfect for every dog in our household and keeps them busy for hours. Since it is curved, it is easy for them to hold on to and to pick up. We have had this bone for a few weeks, and it has lasted through our little dogs, fosters, and Great Dane! The bone is very durable, and based on the previous bones we’ve gotten from Pet Qwerks, I’m guessing it’s going to last quite a while! I recommend this to anyone wanting a long-lasting bone for their pups, especially those tough chewers!

Large and durable!
Size: 1 Count (Pack of 1)
It's large but my pitties love it. I bought this to replace a small one I found at a local store about a year ago and this one is better! Large and durable and a favorite with my boys!

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!
