TRAIN SMARTER POWER METERS

Triathlon Magazine Canada - - Front Page -

It’s be­come one of the most pop­u­lar ad­di­tions to a triath­lete’s train­ing arse­nal. Power meters have be­come the go-to method for ath­letes to gauge their train­ing progress. There are lots of dif­fer­ent ways to mea­sure your power out­put th­ese days – we check out some op­tions you can add to your bike to get the most out of your train­ing and rac­ing.

Pow­er­tap P1 Ped­als

Th­ese su­per-ac­cu­rate ( just like the Pow­ertab hubs, they are ac­cu­rate to 1.5 per cent) power-mea­sur­ing ped­als can eas­ily be switched from one bike to another, mak­ing this a great op­tion for those who have a cou­ple of dif­fer­ent bikes that they train on. Be­cause the ped­als mea­sure each leg separately you can get de­tailed power in­for­ma­tion that helps you fig­ure out how ef­fi­cient you are and helps you work on any im­bal­ances. And, thanks to the Ant+ and Blue­tooth com­pat­i­bil­ity you can eas­ily keep track of your data on a va­ri­ety of head units and watches.

Quarq Dzero

Quarq launched a new up­grade to their al­ready su­per­solid power meters last fall. The Dzero line is more ac­cu­rate, has longer bat­tery life and of­fers more com­pat­i­bil­ity than ear­lier Quarq mod­els. The Dzero still mea­sures power through the spi­der, and can mea­sure left and right power out­put, so you can gauge your ped­alling ef­fi­ciency. As with the old mod­els you can change the bat­tery your­self and you don’t have to re­cal­i­brate the me­ter if the tem­per­a­ture changes. The new ver­sion is both Ant+ and Blue­tooth com­pat­i­ble, so you’ll be able to use a huge va­ri­ety of bike com­put­ers or watches.

Pi­o­neer Dual Leg Power Me­ter

Avail­able for a va­ri­ety of Shi­mano cranksets, Pi­o­neer’s Dual Leg Power Meters use left and right crank arm strain gauges at 12 dif­fer­ent points of each pedal stroke to mea­sure force. Those forces can be dis­played in real time when used with Pi­o­neer’s cy­cle com­puter so you can keep track of just how ef­fi­ciently you’re ped­alling. All that ped­alling data has made this a very pop­u­lar power me­ter for road­ies and triath­letes who love to max out the amount of data they can mea­sure. Weigh­ing in at just 64 g it won’t add much weight to your ride. It’s Ant+ com­pat­i­ble, so it’ll work on most cy­cling com­put­ers and some watches.

Pow­er2­max Type S

Avail­able for a va­ri­ety of Ro­tor, SRAM, Cam­pag­nolo and FSA set­ups, the Pow­er2­max Type S mea­sures your out­put via the crank. You get re­li­able power mea­sure­ment un­der all types of weather con­di­tions. You can also change your chain­rings with­out need­ing to re­cal­i­brate the me­ter and also change the bat­tery your­self. Ant+ com­pat­i­bil­ity will get you off and rolling with many cy­cling com­put­ers.— KM

Garneau

De­signed in co- op­er­a­tion with aero ex­perts Al­phaman­tis, the P- 09 hel­met has min­i­mal frontal sur­face area to keep the hel­met com­pact, while the tail is spe­cially de­signed to pro­mote air­flow at the shoul­ders. The tex­tur­ized golf-ball ef­fect used on the front also helps you cut through the air. Four vents are op­ti­mally po­si­tioned and chan­nel air past your head to help cool you down. The lens lifts up for a fast and easy tran­si­tion and can eas­ily be re­moved with just one hand, too. The com­fort­able straps use a Spi­der­lock sys­tem for easy en­gage­ment.

Spe­cial­ized Giro Scott Gi­ant Rivet Smith S-works Evade Tri

It might have the same shape as a TT hel­met, but of­fers more ven­ti­la­tion and a more com­fort­able fit. The mag­netic buckle will help you fly through tran­si­tion, while the strate­gi­cally placed vents ac­tu­ally draw air around your head to cool you down. A com­fort­able fit is en­sured thanks to the Tri­fix web split­ter fit sys­tem that of­fers a five-step height ad­just­ment and a mi­cro-dial to en­sure you are com­fort­able. Spe­cial­ized says you’ll save 46 sec­onds over 40 km com­pared to a stan­dard road hel­met.

Aero­head Ul­ti­mate MIPS

Scar­ily enough, some of us can re­mem­ber Giro’s Ad­van­tage hel­mets that came out in 1985 – the com­pany was a pi­o­neer in the world of aero hel­met de­sign. Grio’s 32 years in the cat­e­gory has re­sulted in the Aero­head Ul­ti­mate, their fastest hel­met ever. The shell is made with Tex­treme car­bon fi­bre, which is lighter and stronger than other car­bon com­pos­ites. The wrap­around eye-shield is made by Zeiss op­tics for out­stand­ing clar­ity – it’s all held on by a mag­netic an­chor. A com­fort­able fit is en­sured by the Roc Loc air fit sys­tem, while your safety is en­hanced by the in­cor­po­ra­tion of the MIPS sys­tem that redi­rects im­pact en­ergy to pro­vide more pro­tec­tion.

Bollé One Road Premium

You can make the Bollé One su­per-aero or ex­tremely ven­ti­lated, or some­where in be­tween. The re­mov­able aero shells turn the hel­met into an aero won­der, while re­mov­ing the shells of­fers up 31 air “in­lets.” Safety is en­hanced thanks to the safety QR code and spe­cially-de­signed LED light. There’s lots of ad­just­ment to en­sure you’ll get a com­fort­able fit and the in­ter­change­able win­ter and sum­mer lin­ings will keep you rid­ing out­side all-year round.

Ca­dence Plus

Scott’s en­gi­neers were asked to come up with an aero hel­met for the Orica- Greenedge cy­cling team and triath­letes now get to ben­e­fit from their work. While it’s de­signed for road rid­ing, there’s lots to love for triath­letes in­clud­ing the fully in­te­grated vi­sor, the op­ti­mized vents that move air through cool­ing chan­nels in­side the hel­met, the com­fort­able Halo fit sys­tem and MIPS brain pro­tec­tion to pro­vide the ul­ti­mate in safety. There’s even win­ter plugs that you can use when you need less air flow­ing through. This triathlon and TT hel­met is de­signed with aero­dy­nam­ics in mind, but still has some ven­ti­la­tion through the front vents, which are po­si­tioned to di­rect air­flow through the in­ter­nal chan­nels to pro­vide some cool­ing. The El­e­ments Strap Sys­tem uses a Cinch Pro fit sys­tem and head-hug­ging web­bing for a com­fort­able and se­cure fit.

Over­take

This ex­tremely light­weight hel­met pro­vides lots ven­ti­la­tion thanks to the 21 vents that are de­signed to pro­vide lots of air flow with­out hurt­ing aero­dy­namic per­for­mance. Safety is en­hanced by the Koroyd ma­te­rial and you can get this hel­met with MIPS, too, for added im­pact pro­tec­tion. The Va­por­fit ad­justable fit sys­tem en­sures you’ll be com­fort­able, too. A great choice for those look­ing to do a hot, long- dis­tance race or a safety- ori­ented train­ing hel­met that pro­vides lots of ven­ti­la­tion.— KM
