Planet X RT-80

The Planet X RT-80, produced from 2010 to 2017, is a road bike that sits comfortably in the mid-range of Planet X's offerings. Aimed at the serious enthusiast or amateur racer, the RT-80 is built around a carbon fibre frame that balances light weight with aerodynamic efficiency. It slots in above entry-level aluminium models and below the more exotic carbon offerings, giving riders a performance-focused machine without the top-tier price tag.

When it comes to riding the RT-80, its carbon frame ensures a responsive and lively feel, making it particularly adept at tackling climbs and sprints. While the geometry is race-inspired, it's not overly aggressive, which means long days in the saddle remain comfortable. UK roads, known for their mix of smooth tarmac and occasional potholes, are handled with aplomb, thanks in part to the compliant nature of the carbon frame. The handling is precise without being twitchy, and it offers a confidence-inspiring ride in various conditions.

Compared to rivals like the Specialized Allez or the Trek Domane, the RT-80 stands out with its value-for-money proposition. Planet X has always been known for offering solid spec at a competitive price, and the RT-80 is no exception. It often features quality components from reputable brands like Shimano and SRAM, which enhance its appeal. Where it might fall short is in brand prestige or the latest frame technology, but for many, the performance-to-price ratio is compelling.

In the used market, the RT-80 presents itself as a strong contender for those looking to upgrade from an entry-level bike without breaking the bank. Models with full carbon wheels or upgraded groupsets represent the best value, as they offer a step-up in performance without the cost of buying new. It's not uncommon to find well-maintained RT-80s for under £1,000, though prices can vary based on condition and spec.

Potential buyers should be mindful of common issues like worn drivetrain components due to the bike's age. Check for any cracks or damage to the carbon frame, particularly if the bike has seen extensive use. The headset and bottom bracket should also be inspected for wear, as these areas can require maintenance over time. Overall, the RT-80 remains a reliable choice for those seeking a capable and enjoyable road bike experience.

What it's like to ride

The RT-80 delivers a rewarding ride on UK roads, offering a balance between speed and comfort. The carbon frame is both light and compliant, making it suitable for long rides and spirited efforts alike. Its geometry strikes a nice balance, providing a responsive feel without sacrificing comfort, even on less-than-perfect road surfaces. The bike's handling is predictable and confidence-inspiring, whether you're navigating city streets or open country lanes.

Who it's for

The Planet X RT-80 is ideal for cycling enthusiasts looking to step up from an entry-level bike. It's also suitable for amateur racers who want a performance-focused ride without the hefty price tag of top-tier models.

The RT-80 from later years, particularly 2016 and 2017 models, often offer the best value as they tend to have newer components and upgrades. However, any well-maintained model can still be a great buy.
