If you own a Smith Forefront helmet, the suspension system (the internal fit mechanism that keeps the helmet secure and comfortable) can wear out over time. Whether the dial breaks, the straps fray, or the cradle loses tension, replacing these parts is often more affordable than buying a whole new helmet. This guide covers the types of Smith Forefront replacement suspension parts, how to identify what you need, and where to source them responsibly.
Understanding the Smith Forefront Suspension System
The Forefront uses a proprietary retention system called the VaporFit™ (on newer models) or an adjustable fit system with a rear dial. Key components include:
- Rear dial mechanism: Adjusts circumference.
- Cradle / occipital support: Holds the back of the head.
- Straps and dividers: Y-shaped straps with adjustment sliders.
- Clips and anchors: Attach straps to the helmet shell.
- Padding retention: Some internal pads attach to the suspension.
Smith offers replacement kits for many of these parts, but compatibility varies by helmet model year.
Identifying Your Helmet Model and Year
Before ordering parts, check the inside of your helmet for a sticker with the model name (Forefront, Forefront 2, Forefront MIPS) and a date code. The VaporFit system debuted around 2018. Earlier models use a simpler dial system. Knowing the exact model helps you purchase correct replacements.
Common Smith Forefront Replacement Suspension Parts
Replacement Fit System (Dial and Cradle)
The most common failure point is the rear dial. If it skips, sticks, or breaks, Smith sells a complete fit system replacement kit. The kit includes the dial, cradle, and webbing. For VaporFit models, the part number is often 01-xxxxx. For older models, the kit is different. Contact Smith customer service (online chat or phone) with your helmet's model and date to get the correct part.
Replacement Straps and Buckles
Straps can become frayed or the buckle can crack. Smith offers strap systems with pre-attached clips and adjusters. You may need to replace the entire Y-assembly. Beware: Some aftermarket straps don't fit Smith's proprietary clip system. It's safer to use genuine Smith replacement straps (often under $20).
Replacement Padding and Liners
While not exactly suspension, the pads attach to the suspension cradle. Smith sells replacement comfort liners (sweat-wicking, antimicrobial). These are model-specific and come as a set for the Forefront.
Helmet Clips and Anchors
Small plastic clips that hold the straps to the shell can break. Smith does not usually sell these individually, but they may include them in a strap kit. If only a clip breaks, a small dab of super glue may work temporarily, but replace the whole strap assembly for safety.
Where to Buy Genuine Smith Forefront Replacement Parts
Authorized Smith dealers: Bike shops (local or online stores like Competitive Cyclist, Jenson USA). Smith's own website (smithoptics.com) has a spare parts section. You can also call Smith directly. Avoid generic or knockoff parts—they may not meet safety standards.
Tips for Ordering
- Have your helmet's model and size ready.
- Compare part numbers listed on Smith's website.
- Check return policies; some dealers accept returns only if unopened.
- If you're unsure, buy from Smith's official spare parts site or a reputable bike retailer.
Step-by-Step Replacement Guide
While this article doesn't replace professional installation, here's a general process for replacing the fit system:
- Remove the old pad set from the helmet shell.
- Unclip the old suspension webbing from the shell's anchor points (usually plastic tabs).
- Install the new cradle by clipping the webbing into the same anchors.
- Reattach pads (they may stick to the cradle).
- Test the dial tension and adjust strap length.
If you need strap replacement, you'll typically have to remove the helmet's internal shell and thread the new strap through slots. Smith's site often has video guides.
When to Replace vs. Buy a New Helmet
If your helmet is more than five years old or has been in a crash, replace the whole helmet—even if the suspension is fine. But if the helmet is still in good shape (no cracks, no crash history) and only the suspension has worn out, replacement parts are a great way to extend its life. Helmets depreciate over time, but suspension parts are relatively inexpensive (usually $15-$40).
Practical Recommendation
For a broken dial or loose fit system, buy the Smith VaporFit replacement kit directly from Smith. For straps, purchase the OEM strap assembly from an authorized bike shop. Avoid mix-and-match from different brands. If you cannot find the exact part, contact Smith support—they may have inventory not listed online. This approach ensures your helmet remains safe and comfortable for many more rides.
Final note: Always inspect your helmet after any impact. Replacement suspension parts restore fit but do not fix structural damage.
