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

Product Information

With such high pressures, you’ll want a comfortable handle. Some pumps feature a fold-out handle, others offer little to grasp onto. Hose Herbold became the first world champion in downhill mountain biking on one of the first suspension forks made for mountain bikes. 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.

Riders looking to upgrade to a mid-spec enduro fork will appreciate the performance the ZEB Select offers. 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?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. Dia Compe manufactured the next series of forks but later withdrew from manufacturing and disposed of its shares. 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. 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. Dimensions-wise, there are sizes to fit 27.5in and 29in wheels. You can choose between a 38mm or 44mm offset for the 27.5in forks, and 44mm or 51mm for the 29ers. All models use a 200mm brake mount with a maximum rotor size of 220mm.

One common argument is whether air is released from the suspension when the pump is disconnected, or if it’s just air escaping from the pump. To counter such issues, Poertner suggests that whatever you choose to buy, you should treat it as a reference. There is a very non-linear relationship between accuracy, precision and cost,” he explains. “Accuracy and precision are different. The pump itself is solid, with a bleed valve, extra-long hose and comfy handle, though it has quite a small volume so 100 strokes equates to about 81psi. You do have to hold the dial at the front but rubber coating makes that comfortable, though it is possible to get your fingers trapped under the handle – hold the handle to the side, and it’s fine.

However, it requires fewer strokes to inflate the pressure you need, making it ideal for mechanics in a workshop. Finance is subject to application, financial circumstances and borrowing history.

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.

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.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. To learn more about the issues with gauge accuracy and precision, we consulted Josh Poertner, the CEO of pump manufacturer Silca.

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. The Charger RC damper features external low-speed compression and rebound adjustment. Andy Lloyd / Our Media It moved to California a few years later. Turner, who rode motorcycles in his teens, founded a company that sold motorcycle parts at the age of 18. He obtained two patents on suspension forks, one of which he licensed to the major motorcycle and suspension companies.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.
