Dash cam maker Nextbase, which set up the portal, pointed out that driving wasn’t necessarily safer just because there were fewer vehicles on the roads. Most high-speed adjusters work by changing the preload on a spring, which pushes on a shim that holds the valve closed; this spring determines how much damping force is required before the oil can push open the valve and flow past. Believe it or not, hubs are not all exactly the same width. If you have multiple wheelsets you may have noticed that some require a different axle lever position to provide the same tightness. I measured two Boost front hubs I had lying around with a Vernier gauge, and there was nearly 0.5mm difference in width between them. Despite the Covid-19 pandemic, the number of offences reported to the police is actually going up. During the 12-week period between August and mid-October, 3805 videos were uploaded to the National Dash Cam Safety Portal (NDCSP) – 78% more than the average for that length of time.

The air spring is unique to the 38. Rather than the air piston sealing against the inside of the stanchion wall (like most forks), the 38 uses a separate, narrower air sleeve that sits inside the stanchion. The percentage difference between two values is calculated by dividing the absolute value of the difference between two numbers by the average of those two numbers. Multiplying the result by 100 will yield the solution in percent, rather than decimal form. Refer to the equation below for clarification. Percentage Difference = In mathematics, a percentage is a number or ratio that represents a fraction of 100. It is one of the ways to represent a dimensionless relationship between two numbers; other methods include ratios, fractions, and decimals. Percentages are often denoted by the symbol "%" written after the number. They can also be denoted by writing "percent" or "pct" after the number. For example, 35% is equivalent to the decimal 0.35, or the fractions . The mudguard bolts securely into four holes, but is disappointingly short in my opinion. 2021 Fox 38 fork air spring An updated GRIP2 damper uses VVC (variable valve control) on the compression as well as rebound valving (previous GRIP2 had VVC valving on rebound only).Most fork axles squeeze both legs together to clamp the hub between them. So, if the hub is out of spec, the legs won’t be perfectly parallel, and this creates unnecessary friction and wear. Also, because the separate air spring is somewhat isolated from chassis flex, this is claimed to reduce the side-load on the piston when the fork bends. 2021 Fox 38 fork damper According to Fox, the 38 is 31 per cent stiffer laterally, 17 per cent stiffer fore/aft and 38 per cent torsionally stiffer than the 2021 Fox 36. In other words, the ratio of 25 males to students in the classroom is equivalent to 50% of students in the classroom being male. Percentage formula Although the percentage formula can be written in different forms, it is essentially an algebraic equation involving three values.

Those looking for a 160mm-travel fork will be able to choose the 36 or 38, in which case Fox recommends the 38 for heavy or aggressive riders, particularly those using 29in wheels, due to its stiffer chassis. Floating axles might look similar to other axles, but in fact they offer a distinct performance advantage due to their unique ability to match the exact width of the fork’s wheel mounting surface precisely to the front hub flange spacing, thus creating perfect chassis alignment and eliminating unwanted friction between the upper and lower fork legs. Floating axles provide much smoother suspension movement throughout the entire range of the fork’s travel, notably improving sensitivity and overall ride quality. This extra volume prevents excessive and unavoidable ramp up in force as the fork nears the end of its travel and the air in the lowers is compressed into the small remaining volume. This was arguably an issue on the 2020 GRIP2 36 because the damper takes up more volume than the FIT4 damper.Most obviously, the chassis is completely different. Not only are the upper tubes a larger diameter, but the arch, crown, steerer tube and axle are brand new designs. Elliptical steerer tube tech for stiffer forks
