Yes, there are downhill mountain bike trails that feature lockable suspension. Lockable suspension allows riders to switch between a fully active suspension for downhill sections and a locked-out suspension for climbing or smooth terrain. This feature is particularly useful for riders who want to maximize efficiency and control on both the uphill and downhill portions of a trail. Many modern downhill bikes come equipped with lockable suspension systems, and riders can also retrofit their existing bikes with aftermarket lockout systems. **

The best full-suspension mountain bike for you will depend on your specific needs and preferences. Consider factors such as your budget, the type of terrain you'll be riding on, and the level of suspension and components you require. Some popular options to consider include the Santa Cruz Hightower, the Yeti SB130, and the Specialized Stumpjumper. It's important to test ride different bikes and consult with a knowledgeable bike shop to find the best fit for you. **

To adjust the suspension on a full-suspension mountain bike, you will typically find dials or knobs on the front fork and rear shock. Start by setting the sag, which is the amount the suspension compresses under your weight when you are on the bike. Adjust the air pressure or preload to achieve the recommended sag percentage for your weight. Then, you can fine-tune the compression and rebound settings to match your riding style and the terrain you will be riding on. It's important to refer to the manufacturer's recommendations and experiment with different settings to find the best setup for your preferences. **

Yes, it is possible to deactivate the suspension for the rear wheel on full-suspension mountain bikes. Most full-suspension mountain bikes come equipped with a lockout feature on the rear shock, which allows riders to switch between a fully active suspension and a locked-out position. This can be useful when riding on smooth surfaces or climbing uphill where a rigid rear end can provide better pedaling efficiency. Riders can easily activate or deactivate the suspension lockout using a lever or switch located on the handlebars. **

The worth of a full-suspension mountain bike depends on various factors such as your riding style, terrain, and budget. Full-suspension bikes are generally more expensive than hardtail bikes but offer better comfort and control on rough trails. If you frequently ride on challenging terrains and prioritize comfort and performance, investing in a full-suspension mountain bike can be worth it. However, if you mostly ride on smoother trails or have budget constraints, a hardtail bike might be a more suitable option. **

One highly recommended mountain bike with air suspension is the Santa Cruz Hightower. It offers a smooth and responsive ride with its efficient VPP suspension system and adjustable air suspension. The Hightower is known for its versatility and ability to handle a variety of terrain, making it a great choice for all types of riders. Additionally, its high-quality components and durable construction make it a reliable and long-lasting option for mountain biking enthusiasts. **

A full-suspension mountain bike with horizontal suspension typically has a rear shock that compresses and extends horizontally along the bike frame. This design allows for a more linear suspension feel and can provide better traction and control over rough terrain. On the other hand, a full-suspension mountain bike with vertical suspension has a rear shock that compresses and extends vertically, which can offer a more progressive suspension feel and better absorption of big hits. Riders may prefer one design over the other based on their riding style and terrain preferences. **

Full suspension mountain bikes typically do not come with kickstands. This is because the design of the full suspension frame makes it difficult to attach a kickstand securely, and the added weight of the kickstand can affect the performance of the bike. Additionally, many mountain bikers prefer to lean their bikes against something or lay them down when not in use, rather than using a kickstand. If a rider wants to add a kickstand to their full suspension mountain bike, they would need to purchase and install one separately. **
