Review RACE FACE Turbine Mtb Mountain Bike Stem Purple 35.0 50mm Spacers

The **Race ST17TURR3550X0PUR Turbine MTB Mountain Bike Stem** is a high-performance, precision-engineered component designed to elevate the handling and responsiveness of your mountain bike, particularly for riders seeking a blend of aggressive trail capability and refined control. Crafted from lightweight yet durable **6061-T6 aluminum**, this stem features a **35mm clamp diameter**, ensuring a secure and vibration-dampening fit that absorbs road and trail imperfections for a smoother ride. The **50mm length** provides an optimal balance between reach and agility, allowing for quick, precise handling on technical descents while maintaining a comfortable upright position for climbing and endurance rides. The **TURR35** designation indicates a **35mm clamp diameter** with **50mm spacers**, offering versatility for riders who prefer a slightly extended reach or need to accommodate different handlebar widths without sacrificing performance. The **PUR (Purple)** finish not only adds a striking aesthetic appeal but also features a **durable powder-coat** that resists chipping and fading, ensuring the stem remains both functional and visually striking over years of rugged use.

This stem is engineered with **Race s Turbine technology**, which incorporates a **unique internal design** to reduce weight while enhancing stiffness and torsional rigidity. This innovation translates to sharper steering response, reduced handlebar flex, and improved feedback from the bike s geometry, making it ideal for riders who demand precision on steep, technical terrain. The **threaded clamp system** ensures a secure, wobble-free connection to your handlebars, while the **pre-drilled holes** allow for easy installation of stem caps, grips, or bar ends. Whether paired with a wide, aggressive MTB bar setup for downhill dominance or a more compact setup for cross-country efficiency, the ST17TURR3550X0PUR stem delivers a seamless integration that adapts to your riding style. Built to withstand the demands of off-road riding, this stem is a standout choice for serious mountain bikers who refuse to compromise on performance, durability, or ergonomic comfort.

### **Pros and Cons of buying a Race ST17TURR3550X0PUR Turbine MTB Mountain Bike Stem (35.0mm, 50mm Spacers)**

1. **Durability and Performance** The Race Turbine stem is designed for aggressive mountain biking, featuring a robust construction that can handle high-stress riding, including downhill and freeride disciplines. The carbon fiber material provides a strong yet lightweight solution, reducing weight without compromising strength.

2. **Adjustable Reach and Comfort** The inclusion of 50mm spacers allows for fine-tuning the reach, which can improve ergonomics and reduce wrist strain during long rides or technical descents. This adjustability helps riders find an optimal position for better control and comfort.

3. **Compatibility with Wide Q-Factors** The 35.0mm clamp width accommodates modern wide Q-factor forks and frames, making it suitable for bikes with a more aggressive, stable geometry. This is particularly useful for downhill or enduro bikes where stability is critical.

4. **Aesthetic and Brand Reputation** Race Bikes is a well-known brand in the mountain biking and BMX communities, offering high-quality components with a reputation for reliability. The purple (PUR) finish adds a stylish touch for riders who prefer a custom look.

5. **Easy Installation** The stem is designed for straightforward installation, requiring basic tools. The clamp system is secure, and the spacers can be adjusted without special equipment, making it a practical upgrade for DIY-oriented riders.

6. **Versatility** While optimized for aggressive riding, the stem can also be used on cross-country or trail bikes with proper adjustments, making it a versatile choice for different disciplines.

1. **Cost** High-quality carbon fiber stems like the Race Turbine are more expensive than aluminum or plastic alternatives. For riders on a tight budget, this may be a significant investment, especially if they don t need the full performance benefits.

2. **Specialized Use Case** The stem is tailored for aggressive riding (downhill, freeride, or hard-hitting trail riding). Riders who primarily use their bike for leisurely cross-country or casual trail riding may not see a significant performance improvement and could opt for a more budget-friendly stem.

3. **Weight Sensitivity in XC** While the carbon fiber stem is lightweight, some cross-country riders prioritize minimal weight above all else. In this case, a lighter aluminum or titanium stem might be preferable despite slightly less stiffness.

4. **Potential Overkill for Some Riders** If a rider s current stem is already adequate for their riding style, upgrading to this stem may not offer noticeable benefits and could be seen as unnecessary.

5. **Compatibility Issues** While the 35.0mm clamp width is common for modern bikes, riders with older or non-standard fork setups may need to verify compatibility. Additionally, the stem s length and angle must align with the bike s geometry to avoid handling issues.

6. **Maintenance Requirements** Carbon fiber components require careful handling to avoid scratches or damage, which could affect performance or aesthetics over time. Unlike metal stems, they are not repairable if damaged.

The **Race ST17TURR3550X0PUR Turbine stem** is an excellent choice for riders who prioritize durability, adjustability, and aggressive riding performance. Its carbon fiber construction, wide clamp compatibility, and adjustable reach make it ideal for downhill, freeride, or hard-hitting trail riding. However, it may not be the best fit for budget-conscious riders, casual riders, or those who need ultra-lightweight components for cross-country riding.

If you ride aggressively, value adjustability, and want a premium stem that enhances control and comfort, this is a strong recommendation. For other riding styles, consider alternatives like aluminum or titanium stems that offer a better balance of weight and cost.

- You ride aggressively (downhill, freeride, or technical trails).

- You want a durable, lightweight stem with adjustable reach.

- Your bike s fork and frame are compatible with the 35.0mm clamp width.

- You re willing to invest in a high-performance component.

- You primarily ride cross-country or casual trails.

- You re on a tight budget and can find a suitable aluminum stem for less.

- Your bike s geometry doesn t benefit from the stem s specific length or angle.

- You prefer a stem with even lower weight (e.g., titanium options).
