Trek Emonda ALR 4 Road Bike 2019 in Charcoal Size 52cm Only

Season : 2019

Brand : Trek

Code : XXX549849

Weight : 20KG

The 2019 Trek Émonda ALR 4 is an entry-level aluminium race bike with a full Shimano Tiagra groupset, a carbon fork and direct mount rim brakes.

Émonda ALR 4 is a lightweight aluminium road bike at incredible value. But don't mistake it for the kind of ride you'll get from value-minded competitors at this price. Shaped tubes, Invisible Weld Technology and a lightweight frame that's perfect for new riders and racers alike give Émonda ALR the looks and handling of carbon at the price of alloy.

Émonda ALR 4 is more than the sum of its parts. Yes, it has a full Shimano Tiagra groupset, 20 speeds, a carbon fork, powerful direct-mount rim brakes and a lightweight 300 Series Alpha Aluminium frame with shaped tubes – but its real genius is in its handling and ride quality.

Émonda ALR 4 is the most affordable Émonda in the family, but it handles like a far more expensive bike and has the looks to match. It's an extremely capable racing bike at a great price.

Road Bike Sizing Guide

Road bikes as the name implies are for road use. There are a growing number of “gravel” or “adventure” bikes which are based on road bicycles, but feature wider and more versatile tyres and disc brakes, so you can also do light trail riding such as towpaths. They are also more pothole resistant!

Sizing is normally in cm, and is a measurement from the centre of the chain-wheel axle (The BB or bottom bracket) and the top of the frame seat tube. Some are measured to the centre of the seat tube where it meets the top tube (otherwise known as the crossbar).

That measurement is on road bikes normally in CM – and no-one really knows why! Some road bikes will use “T-Shirt Sizing” so S, M, L, XL etc. but there will be a geometry chart that then shows the measurement in CM.

What is your height? Your suggested bicycle size
Feet/Inches Centimetres Suggested Size
4'10" - 5'0" 148cm - 152cm XX-Small (47-48cm)
5'0" - 5'3" 152cm - 160cm X-Small (49-50cm)
5'3" - 5'6" 160cm - 168cm Small (51-53cm)
5'6" - 5'9" 168cm - 175cm Medium (54-55cm)
5'9" - 6'0" 175cm - 183cm Large (56-58cm)
6'0" - 6'3" 183cm - 191cm X-Large (58-60cm)
6'3" - 6'6" 191cm - 198cm XX-Large (61-63cm)

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.
