Rock Shox 00.4315.023.010 High-Pressure Fork Pump, Black, 300 psi

Product Information

At 284g and 250mm long, it’s an impressive combination of two pumps, especially given so many mini tyre pumps do without a gauge. Additionally, remember that the pressure may change due to outside temperature. This phenomenon is referred to as Charles’s law. Therefore, if you plan to ride in the winter, inflate the suspension slightly as pressure decreases due to the cold temperatures, and vice versa. Two years later Turner and his wife Christi were producing suspension forks in their garage using parts they bought from Simons. The Charger RC damper features external low-speed compression and rebound adjustment.

Reasons to buy: Presta adapter means this pump works on tyres and suspension, high pressure and high volume modes, neat design, frame clip included, compact size To counter such issues, Poertner suggests that whatever you choose to buy, you should treat it as a reference. He would go on to work for the Honda Motor Company as the factory motocross team's mechanic, which put him in touch with suspension designers and other motocross industry leaders. However, weight and price make the Manitou a more attractive option. Both forks enable the same type of external adjustments, so you’ll need to dig a little deeper to work out which is best for you.

RockShox High-Pressure Fork/Shock Pump - 300 psi Max

Riders looking to upgrade to a mid-spec enduro fork will appreciate the performance the ZEB Select offers.

The taller ride height and extra travel are useful on steeper trails, where the front end doesn’t dive through the mid-stoke. However, losing the ground-hugging sensitivity of the mid-stroke that made the DebonAir spring so comfortable limits confidence over small root spreads and unsupported corners where traction is necessary. No matter what type of bike product your buying, from the simple accessories through to the full setup of your custom built road bike, there are lots of important considerations that you should take into account, especially when you’re shopping online and unable to test the product first. This is especially true when you’re buying products like Pumps. If you want both pumps in one, this is simply your one and only good choice. It’s also the only pump on test to include an under bottle-cage mount – in case you’re keen to get it covered in mud. In 1987, Turner had presented a full bike with front and rear suspension at the bicycle industry trade show in Long Beach, with the help of Keith Bontrager.I analogise it to throwing darts: accuracy is how close you are to the bullseye, so for a gauge, how close is 100psi to 100psi? Easily the most efficient pump that we’ve tested, and one that outperforms its price. The mechanical isn’t quite as accurate as a digital pump, but it has a bigger range being rated to 400 psi.

Herbold became the first world champion in downhill mountain biking on one of the first suspension forks made for mountain bikes. He obtained two patents on suspension forks, one of which he licensed to the major motorcycle and suspension companies. With such high pressures, you’ll want a comfortable handle. Some pumps feature a fold-out handle, others offer little to grasp onto. Hose If you’ve ever used a low-quality pump, you know how unpleasant the experience can be. You may feel like the pump could break at any moment.The start-up was financed by the East Asian bicycle parts manufacturer Dia Compe, the founders, and other investors. There is a very non-linear relationship between accuracy, precision and cost,” he explains. “Accuracy and precision are different.

However, it requires fewer strokes to inflate the pressure you need, making it ideal for mechanics in a workshop. Because it’s still quite compact, we found that it does take a while to inflate a tyre but is great for suspension setup since you can use the high-volume setting to initially boost a load of air into your fork, then the high-pressure setting to fine-tune it. We managed to get about 70psi in 20 strokes. The ZEB Select offers more mid-stroke support, but can’t provide as much in terms of sensitivity. The Manitou fork better manages to deliver on both, with plenty of ground-hugging traction, yet it stays composed when the going gets rough. The new Charger RC damper no doubt plays a role here too. However, the damping feels light enough when open that it doesn’t restrict travel and the spring supports the rider’s weight. Precision is how repeatable your darts are. If you aren’t always hitting the 20 but you can tightly cluster your darts, you are inaccurate but precise. Similarly, if you hit left of bullseye, bullseye and right of bullseye, your average accuracy would be good, but your precision would be bad.”On the downside the pump isn’t very comfortable to use since you have to grip around the gauge and the handle has quite a blunt shape. That added support helps keep the front end high so you can push and load the handlebars in turns, which helps maintain momentum in some circumstances, such as high-speed berms and pumping jump faces or rollers. Still, it gives a bit of harshness through the hands. There is also minimal friction in the fork, which helps give it a plush feel. The progression with the new spring is impressive, and it was tough to reach full travel, even when running lower pressures than suggested. The ramp-up is gentle, however, because the mid-stroke support is also firmer. Dia Compe manufactured the next series of forks but later withdrew from manufacturing and disposed of its shares. This update to this fork suits those who are looking to push hard and ride fast everywhere. It seems more like a bike park fork than its predecessor. Support has increased, but comfort is compromised, although it’s tough to improve both at the same time. Go full-tilt and it’s a strong-performing fork for the price.
