Bicycling (South Africa) - - STORIES -

A com­mon com­plaint among moun­tain bik­ers is the in­abil­ity to set up their sus­pen­sion ac­cu­rately – of­ten, it’s to­tal guess­work. Tens of thou­sands of rands worth of bike can be ren­dered to­tally in­ef­fi­cient (and even down­right dan­ger­ous) if sus­pen­sion isn’t cor­rectly tuned.

Quarq’s Shock­Wiz is a small, au­to­mated, wa­ter­proof rear-shockand-fork tun­ing de­vice that uses a highly sen­si­tive pres­sure sen­sor and mi­cro­pro­ces­sor to mea­sure changes in your shock or fork’s air pres­sure, 100 times per sec­ond, while you ride.

Ride data is recorded and stored on the de­vice, and eas­ily down­loaded to the Shock­Wiz smart­phone app. Quarq’s al­go­rithm (de­vel­oped from thou­sands of hours of lab and real-world test­ing) analy­ses the data and sug­gests air pres­sure, spring rate, com­pres­sion and re­bound set­tings, all of which is dis­played in the app.

If you don’t trust your­self, we’ve chat­ted to bike shops such as Stoke Sus­pen­sion Works – who spe­cialise in, er, sus­pen­sion work – and they have plans to buy two Shock­wiz’s, al­low­ing cus­tomers the op­por­tu­nity to fine-tune their own sus­pen­sions, with the help of the pro­fes­sion­als.

So in 2018, there’ll be no ex­cuse for ven­tur­ing into the realm of sub­op­ti­mal sus­pen­sion set-ups…
