Rotor 2INPower Spider Features

Save time and money

We sell the 2INPower crankset as a bundle : saving you money and also time shopping round for individual components.

Fits all road & TT bikes

Retro-fit your existing bike and gearing system, or optimise your new set up.  The Spider is compatible with all bottom brackets, comes with either a 4-bolt or 5-bolt spider, various chainring sizes and crank lengths.  Compatible with both SRAM and Shimano gearing systems.  This is a fully customisable system to find your perfect fit.

Left-Right power measurement

The 2INPower meter records high-rate precision data from 4 sets of opposing gauges, showing independent power readings from right and left legs.  This enables you to work you your ideal power balance and make the most of every pedal stroke.  

Compatibility

Connect to your bike computer through ANT+™ and Bluetooth® Smart, so you can see your bike power whilst training on Zwift, Garmin or other platforms.

Easily analyse data with Training Peaks.  Training Peaks offer a free 'Fundamentals of Power' Training Plan to help you get started.

Data analysis

The ROTOR Power App shows the kind of data normally reserved for the pros, including:

  • TORQUE 360 and power stroke effectiveness

  • Optimum Chainring Angle (OCA) helps to identify your optimal chainring position

  • Pedal smoothness

Rotor 2INPower Spider Options

You can build your own 2INPower Spider system to suit your own requirements.  See our Rotor FAQ for more indepth answers, but in brief:

4-bolt or 5-bolt?

This purely depends on your set-up - there is no advantage to 4 or 5 bolt systems, so if you are buying a full new chainset, you can choose either.  4-bolt Spiders fit newer Shimano chainsets, whereas 5-bolt used to be the standard.

Crank length?

Choice of 165mm, 170mm, 172.5mm or 175mm.  This depends on the height and leg length of the rider.  165mm suits a 5'4" rider, whereas a 6'2" rider will want 175mm.  It is a myth that shorter cranks suit triathletes better.

Q Rings or Round rings?

The oval shape of the Q-rings is designed to optimise the force applied to the pedal, by making the downward part of the pedal cycle a larger gear size, whereas the recovery stage is in a smaller gear.  They are particularly useful when on the cusp of needing to change up or down gear, but can be tricky to master.  See more info on Q-rings here.

Chainring sizes?

The spider is compatible with both 1x and 2x chainring systems.  The standard chainring set size is a 39/53 2x, which will suit most riders. 

You may want a smaller size (e.g. 34/50) if you are a slower rider, or if you will be climbing lots of hills.

1x systems (a single front chainring) are mostly for TT riders who rarely change the front chainring as they have an optimal set up with sufficient range for flat courses on the rear cassette.  They would most likely use a 54T or similar.

 If you want a chainring combination not listed here, including aero rings, please leave a note at the checkout, along with a phone number and we will confirm your personal combination.
