You MIGHT have to replace the control cables from stock, like we did. So far, they are working fine. Make sure you crank that internal bolt down tight, then tap it again to lock it in place. ### ⭐⭐⭐⭐⭐ Recommend *by A***S on May 15, 2025* Strong and well built. ### ⭐⭐⭐⭐⭐ Purchased to replace a missing piece on a kids bicycle handle *by L***A on April 23, 2025* I just needed some pieces from this item to fix a Joystar Kids bike handle and it worked like a charm. ## Frequently Bought Together - ZUKKA Bike Stem Quill Adapter, Bicycle Fork Stem Riser Extender 22.2/25.4 mm to 28.6mm for 1-1/8" Threadless Size Converter - 31.8 Stem 45mm Bike Stem Wake Mountain Bike Stem Short Handlebar Stem for Most Bicycle, Road Bike, MTB, BMX, Fixie Gear, Cycling (Aluminum Alloy, Black Blue Gold Red) - Kbrotech Bicycle Headset Spacer Aluminium Alloy Bike Stem Headset Spacers Fork Washer Fit for 1 1/8-Inch Stem 2mm 5mm 10mm (8pieces) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/469557064-zukka-bike-stem-quill-adapter-bicycle-fork-stem-riser-extender](https://www.desertcart.tn/products/469557064-zukka-bike-stem-quill-adapter-bicycle-fork-stem-riser-extender) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-06*
