The front wheel was everything I was expecting....thx

Did not come with the disc. I’ve been meaning to call but been busy. Please send me one and I’ll give you 5 stars.
Thank you for completing my order in a timely manner.
HI Kevin,
Apologies for the oversight on the rotor. We did however send it a few weeks ago. This was the only communication we had about the missing part and were not on the reviews dashboard often. Next time feel free to reach out to us by phone or direct email.
This brake is a must once kids start to carry speed! Total game changer and how the bike should be sold!
Must have upgraded for those riders with small hands. We painted our bracket black. I think it looks better black.
Hi Daniel,
Thank you for taking the time to leave a review on our AZ Racing Rear Disc Brake Kit. We're glad to hear that you found it to be a great upgrade, especially for riders with smaller hands. We love the idea of painting the bracket black for a personalized touch. Happy riding!
Andrejs, Thank you for taking the time to leave a review! We're thrilled to hear that our AZ Racing Stacyc Rear Disc Brake Kit was a perfect fit for your son's bike. We hope he enjoys using it and thanks again for choosing JDubs. Happy riding!
Great kit and very well thought out. This gave my kid the confidence to ride her stacyc on Trails with a downslope that she would walk with the stock drum brake. You do need a means to bleed the brake since you have to disconnect the caliper from the hose to route it through the stacyc. so if you don’t work on bicycles with Shimano brakes the. You’ll likely have to take it to a shop to get it bled after Install. All that being said when my kid sizes up to the 16”stacyc, this will be going on before she even gets to swing a leg over it.
Love this new brake kit for my daughter’s Stacyc. A definite upgrade from stock and easy to install! Great company with amazing products and customer service!
This setup has created such a confidence booster for my little one! This is a must buy!
note: buy the brake bleed kit
Hi Shane! Thank you for leaving a review for our AZ Racing Rear Disc Brake Kit. We are thrilled to hear that it has been a great decision for your little one and has boosted their confidence. We agree that the brake bleed kit is a must-have addition. Ride on!
Good kit. Much better than stock for braking power. Fixed the issue of little guy not being able to reach and pull in stock setup. Only thing I would add to kit is a small bottle of hydraulic fluid or at a minimum, recommend some hydraulic fluid to be purchased as well.
Thanks so much for the review and feedback. Great suggestion we can look into offering.
