Do you know what all of the little knobs on your fork do? If you do, are they set right? Are you sure, or do you think you’re sure? The Folks at SussMyBike says they can help and have a device & smartphone app that takes the guessing out of suspension setup. In regards to setting up a bike, I’ve never wanted something to work as much as this and am surprised it took this long.
Rebound past the break to find out what we know about it and let us know what you think….
It’s not uncommon to be sitting at the trail head and hear, “I like to run my suspension a little stiff”, or my favorite, “I run the factory recommendation minus 1opsi, check sag, add 2 to 3.25 psi, compression 1 click from open, rebound 12 clicks from open… plus a couple more for good measure with my forks”. Current suspension setup involves a little bit of measuring, a little bit of counting clicks, a little bit of “feel”, and just as much personal voodoo/secret sauce.
Though soaking up big hits is important, the key to a good suspension setup is keeping the tire in contact with the ground. Every time your tire leaves the ground, you lose control of that wheel until it connects again. Linear Displacement Sensors have been used for years on Moto GP and other race motorcycles to measure how the suspension performs on various courses. These measure amount of travel as well as speed of travel and can tell if the suspension is having trouble “packing down” (not rebounding fast enough before compressing again and eventually not having any travel left), or if rebound is set too fast. SussMyBike looks to have a version for mountain bikes in the works and is preparing to launch a crowdfunding campaign this month.
The SussMyBike project is being headed up by Scotsman Alan Mason with support from the Mountain Bike Centre of Scotland (MBCOS) and Edinburgh and Napier Universities. They have a smartphone app in development that is said to read data from the SusMyBike’s unit and then tells you what you need to adjust to improve the bike’s suspension performance.
They don’t go into a lot of detail about how the device works but from what we can tell, the unit contains a retractable wire, (think security badge tether), that is attached to the fork’s lowers and stanchion. As the fork cycles, the wire’s movement spins a wheel inside the unit with a sensor that sends data to your smartphone via Bluetooth or Ant+. The data then gets analyzed and gives you some calculated advice to properly set up your fork.
Does it graph out the fork’s performance? Can you program settings for various trails in the app so you can easily tweak the settings for primo performance everywhere you go? We’ve reached back out to Alan to find out, so look for updates and future coverage on this neat little tool.
