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

Product Information

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. The start-up was financed by the East Asian bicycle parts manufacturer Dia Compe, the founders, and other investors.

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.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.

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. 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. 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.

Riding across small bumps, the new ZEB isn’t wonderfully supple like older models. It doesn’t take the sting out of chattery trails as well as forks such as the Formula Selva R or Cane Creek Helm MkII. This will win some people over but not others.

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. 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. 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. 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.

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 Dia Compe manufactured the next series of forks but later withdrew from manufacturing and disposed of its shares. 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. There is a very non-linear relationship between accuracy, precision and cost,” he explains. “Accuracy and precision are different.
