Giant TCR Advanced SL Rim-Brake Build Review: Mechanical Speed at 6.92 kg

Introduction

Rim brakes are now a minority choice on high-end road bikes, yet a carefully chosen rim-brake build still has a clear case behind it. This Giant TCR Advanced SL is a useful example. It pairs the current-generation frame with mechanical Campagnolo Super Record, Campagnolo Bora Ultra 35 wheels, and 25 mm Michelin Power Cup Competition tires, and the complete bike weighs 6.92 kg, which lands right at the UCI minimum weight limit.

The frameset was bought for around £2,400 after shopping around, well below the most exclusive framesets on the market, which can sell for more than twice that. The rest of the build follows the same thinking: light components, mechanical shifting, and no batteries to charge.

Who This Build Is For

This bike suits riders who still put low weight above almost everything else. The TCR Advanced SL is the current model, and it is slightly lighter and slightly more aero than the previous generation, while keeping classic frame shapes, an integrated seatpost, and clearance for 28 mm tires.

It also makes sense for riders who handle their own maintenance. Rim brakes are simpler to live with at home: a pad or cable adjustment is typically a ten-minute job rather than a thirty-minute one, and it does not call for a bleed kit or a syringe. The trade-off is that rim brakes generally need attention more often.

Looks matter here too. Rounded tubes, a restrained paint finish, and less hidden cabling give the bike a traditional appearance, and the simpler routing makes routine work easier.

Main Strengths

The core argument for this build is the combination of low weight and mechanical simplicity. The finishing kit comes from earlier lightweight hill climb builds, so there is plenty of carbon in the mix, which helps hold the total at 6.92 kg without resorting to exotic one-off parts.

The Frameset: Giant TCR Advanced SL

The TCR Advanced SL has a long-standing reputation as a fast all-round road frame. This generation is a little lighter and a little more aero than the version before it, while preserving the same character: classic tube profiles, an integrated seatpost, and room for 28 mm tires.

At around £2,400 for the frameset, it is far from cheap, but it sits well below the most expensive framesets available. For riders who want a high-end platform without flagship pricing, that difference is significant.

The rim-brake design is central to the whole build. It keeps weight down, avoids hydraulic maintenance, and preserves a cleaner, more traditional look.

The Groupset: Campagnolo Super Record

Campagnolo Super Record is an indulgent choice for almost any build. The mechanical version was selected specifically to keep weight low while avoiding batteries and charging, and it delivers the tactile feel that mechanical groupsets are known for: a firm clunk rather than an electronic tone.

The hoods have a deep, contoured shape, and the thumb-actuated downshift lever remains a distinctive Campagnolo detail. Because the shift levers are fully separate, riders who prefer that layout often find the shifting more precise. The mechanical finish also has a more organic appearance than its electronic counterpart.

The Wheels and Tires: Campagnolo Bora Ultra 35 and Michelin Power Cup Competition

The Bora Ultra 35 wheels are a traditional choice in the sense that they are neither especially wide nor especially aero, but they suit the build well. At around 1,360 g for the pair, they are light for carbon clinchers, and the rim graphics tie in neatly with the frame.

The tires are 25 mm Michelin Power Cup Competition with tan walls. That width is unusual on a new road build today, but it keeps weight down, and the tires size up nicely on the Bora Ultra 35 rims.

Riders who want more comfort or more grip may prefer a wider tire, and the frame will accept up to 28 mm. The narrow setup is a deliberate trade-off in favour of low weight.

Things to Consider Before Buying

The main consideration is that rim brakes are a shrinking category. Fewer new rim-brake frames and components are being developed, so the available choice is narrower than it once was, and disc brakes offer stronger stopping performance, particularly in wet conditions.

Rim brakes also need more frequent attention than hydraulic discs, even though each individual job tends to be quicker.

The build itself is deliberately minimal on data. A computer mount is fitted, but there is no head unit and no power meter, so riders who train with numbers would need to add both. At 6.92 kg the bike already sits at the UCI minimum weight limit, which leaves almost no margin for heavier components.

Buying Advice

If low weight, mechanical shifting, and straightforward home maintenance are the priorities, this style of build still holds up. The Giant TCR Advanced SL frameset is a sensible starting point: it is lighter and more aero than the previous generation, it accepts 28 mm tires, and at around £2,400 it costs far less than the most exclusive framesets.

Campagnolo Super Record is the indulgent element. Mechanical Super Record keeps the build free of batteries and charging, and the separate shift levers and contoured hoods are a large part of the appeal. Where budget matters more than weight, a lower-tier groupset such as Shimano 105 remains good enough for most situations and would deliver much of the same simplicity.

The Bora Ultra 35 wheels and 25 mm Michelin Power Cup Competition tires complete the picture. The wheels are light carbon clinchers rather than a modern wide, aero design, and the tires are narrower than most riders would choose today. Riders who prioritize comfort and wet-weather grip may want a wider setup, while those chasing minimum weight will find this combination hard to argue with.

Conclusion

This build shows that rim brakes and mechanical shifting still have a coherent case: low weight, simple maintenance, and a traditional look. The Giant TCR Advanced SL frameset is the foundation, Campagnolo Super Record supplies the mechanical feel, and the Bora Ultra 35 wheels and Michelin Power Cup Competition tires keep the total at 6.92 kg.

It is not the fastest or the most practical option for every rider. For someone who values a light, easily maintained, good-looking road bike, though, it remains a build that makes sense.
