Measure cadence, speed, distance, time and temperature with a slim cycling computer!

When looking at cycling computers, you need to ensure that it will function reliably, with robust mounting brackets and an easy to read display that gives you all the information you need.

Wired computers are robust and reliable, with a solid connection.

One key function of higher-grade cycling computers is measurement of cadence, which is the revolutions per minute of your pedals. Measuring cadence is critical to effective training. The Sigma measures both current and average cadence.

A good quality cycling computer like the Sigma will enable you to track your training progress, estimate the distance to your destination and keep an eye on the time. It also features a programmable service interval notification, so you can track the distance between bike services and keep your ride running well.

All parts of the computer are well-made and rugged.  Its weather-proof design and large, well laid out LCD display will give you quick, reliable readings. The display (called a head unit) can be attached to flat bars or drop road bars without tools.

The fork-mounted speed sensor is fixed with rubber bands or cable ties for a very secure attachment. The wheel magnet clips on securely. The body of the head unit is a sharp black.

Size Guide



Reid Cycles ships bikes, parts and accessories anywhere in Australia!

Free shipping of bikes is available to most metropolitan and some regional areas. We also combined shipping wherever possible to keep the price down. Once you have one or more items in your cart, view your cart, pop your postcode in and we'll give you the combined shipping price. We are currently unable to ship to overseas addresses, please contact our customer services team to enquire about distributors in your area.

We aim to keep the price as low as possible by shipping smaller items for free if they can be shipped with larger items. Helmets, shoes and parts most often ship for free with your new bike!

Remember that bikes are shipped boxed, and 85% assembled. The final assembly required includes the installation of the handlebars, front wheel, pedals and saddle, adjusting the brakes and tuning the gears. We recommend that the assembly is done by a qualified bike mechanic or other suitably qualified person. Damage caused by incorrect assembly (such as installing the pedals the wrong way around) is not covered by your warranty.


Orders for items that are currently in stock are usually despatched within 1 to 2 working days. You'll receive an email with tracking information once the order has been despatched. Certain periods of the year are seasonably busy, with much higher volumes than normal. At these times, we still aim to despatch within 1 to 2 days, but deliveries may take a little longer due to our couriers' workload.

It's always best to send to an address that always has someone in attendance, such as a business address. You may also want to give our courier an 'authority to leave' instruction, which is an instruction to say that there is a safe place leave to delivery, even if there is no one there to take delivery. Only give us an 'authority to leave' if you're confident that the delivery will be safe. Otherwise, the courier can leave a 'sorry we missed you' card, allowing you to arrange redelivery.

Please contact us if you have any questions.
