TIRGE Store 28mm to 7/8″ & 1 1/8″ Converters
Features: This CNC-machined aluminum alloy clamp is designed for durability and anti-rust performance. The universal design accepts 28mm (1 1/8″) bars and converts to a 7/8″ diameter with a 1.2-inch adjustable height. Best for riders who want a single, reliable riser system that fits multiple bar sizes and can be installed with basic tools.
Best for: Riders who ride multiple bikes or plan long-term bar upgrades and want one set of spacers that covers several diameters. The set is particularly suitable for dirt bike, pit bike, and ATV riders looking for a robust, long-lasting solution.
Caution: Some users may need to confirm clearances within triple clamps or handlebar clamps due to added height. Ensure the conversion does not interfere with brake lines or cables.
SING F LTD 1 Pair 28mm to 22mm Reducers
Features: Includes 1 pair of sleeves (two per side) crafted from high-density aluminum alloy with an anodized finish. They convert 28mm and 25mm bar sizes down to 22mm, delivering precise fit and rust resistance for rugged riding conditions.
Best for: Riders who want precise, lightweight reducers with a durable finish that resists wear and rust. Ideal for upgrading existing fat bars to standard 7/8″ without compromising alignment.
Caution: Anodized color may vary; confirm compatibility with your bar diameter before purchasing. Avoid using without proper torque to prevent loosening over time.
8pcs Handlebar Riser Spacers For 1 1/8″ To 7/8″ Bars
Features: This spacer set provides multi-diameter compatibility, allowing replacement between 28mm/1 1/8″, 25mm/1″, and 22mm/7/8″ diameters. It enables straightforward reshaping of your handlebar setup to match your preferred control and comfort zone.
Best for: Riders who switch between multiple bikes or bars and want a single spacer kit to cover several common diameters. It helps with quick, tool-light changes at the trailhead.
Caution: The set contains spacers of various sizes; keep track of which spacer goes where to maintain proper clamp alignment and safety.
TC-Motor 1 1/8″ To 7/8″ Spacers
Features: Aluminum spacers, four pieces included per pack, designed to convert 1 1/8″ handlebars to 7/8″ diameter on ATVs, dirt bikes, and pit bikes. The product promises straightforward installation and a snug fit.
Best for: ATV and dirt-bike riders who want a compact, four-piece spacer kit that makes quick bar diameter changes without removing entire handlebar assemblies.
Caution: Verify your bike’s clamp compatibility with four-piece spacer kits; misalignment can lead to improper torque distribution if installed incorrectly.
HandleBar Clamps Riser Universal CNC For EXC SX CRF YZF
Features: High-performance alloy handlebar riser compatible with 22mm and 28mm bars, offering 1.2-inch height adjustment. The machine-cut design emphasizes light weight and precision, with easy installation.
Best for: Riders seeking a robust, universally compatible riser that suits multiple bike models (EXC, SX, CRF, YZF). It supports easy customization of handlebar height for a personalized riding stance.
Caution: Ensure your existing clamps have adequate clearance for added riser height; contact points may require re-tightening after initial ride-in to prevent slippage.
Buying Guide: Key Considerations for 1 1/8″ to 7/8″ Handlebar Shims
What diameter range do you need to convert? Decide whether you need 28mm to 22mm, 28mm to 7/8″, or 1 1/8″ to 7/8″ compatibility. Look for sets that include all necessary spacers and sleeves in a compact kit to minimize purchases.
What material matters? Aluminum alloys and CNC machining improve durability, reduce weight, and resist corrosion in wet or muddy riding conditions. Anodized finishes add rust resistance and color consistency.
How easy is installation? Seek screw-friendly designs with simple alignment and clear instructions. Some kits include four pieces or multiple spacers to cover many bar sizes, simplifying installation and future maintenance.
Is height adjustment important? Some models offer up to about 1.2 inches of height adjustment. This helps tailor riding posture, reduce back strain, and improve control for different riding styles.
Potential limitations: Clearance with triple clamps, brake lines, throttles, and cables. Some conversions may require checking frame and clamp compatibility to avoid rubbing or binding during steering.
FAQ
- What is the difference between a reducer sleeve and a spacer? A reducer sleeve lowers a larger diameter bar to a smaller diameter to fit clamps, while a spacer fills space between components to adjust height or alignment.
- Can I convert from 1 1/8″ to 7/8″ without removing the handlebars? Yes, most spacers and reducers are designed to be installed with existing clamps, but verify clearance and torque specs first.
- Are these shims compatible with all dirt bikes? Compatibility varies by model and clamp design. Check the product specifications to ensure fit with your bike’s bar diameter and clamp style.
- Do I need special tools to install these spacers? Typically no; many spacers require only standard tools like hex keys or wrenches. Follow torque recommendations supplied by the manufacturer.
- Will anodized finishes wear off? Anodized finishes resist wear but can fade with heavy use. This does not affect structural integrity.
- Should I use thread-locking fluid on bolts? Light thread-locking is often recommended to prevent loosening, but follow the manufacturer’s guidelines for your specific kit.
