Fischer TopLine L roof bars for open rails review

Not a bike carrier but the aluminum crossbars a roof carrier needs, rated at 90 kg (198.4 lb), for open roof rails, with a 20 mm (0.79 in) channel that accepts a range of accessories.

Our conclusion The honest inclusion in a roof rack comparison: the bars are usually the bigger purchase, and this is a well-rated set for open rails.

This is in the hub because a roof carrier without crossbars is not a solution, and the bars are frequently the larger cost.

What the manufacturer publishes

A high-quality aluminum base carrier for open rail systems. Supplied preassembled for quick fitting. A dust-protected lock with two keys. A 20 mm (0.79 in) channel allowing a wide range of accessories to be mounted. A load capacity of 90 kg (198.4 lb).

Open rails only

This is the constraint that decides whether it is relevant to you. Open rails run front to back with a visible gap underneath. Flush rails sit tight to the roof, a bare roof has neither, and fixed points are small threaded mounts under covers. Each needs a different bar system, and they are not interchangeable.

The 90 kg (198.4 lb) figure, and the one that overrides it

Ninety kilograms is what the bars are rated for. Your car has its own maximum roof load, published in the vehicle handbook, and it is frequently lower — 75 kg (165.3 lb) is common. The lower of the two governs, and it includes the bars themselves.

The 20 mm (0.79 in) channel

The practical benefit of buying bars with a standard channel: bike carriers, roof boxes and ski holders from many makers will mount on them, rather than tying you to one manufacturer’s ecosystem.

What we rate and what we flag

Strengths

  • A 90 kg (198.4 lb) rated bar, which is generous and published — most bar listings are vaguer
  • A 20 mm (0.79 in) channel, so bike carriers, roof boxes and ski holders all mount
  • Supplied preassembled with a dust-protected lock and two keys

Compromises

  • Open roof rails only — no use on a bare roof, flush rails or fixed points
  • It is not a bike carrier: you still need one on top of it
  • The car's own roof load limit may be lower than the bars' 90 kg (198.4 lb)

The questions riders ask

Is this a bike carrier?

No. These are the crossbars a bike carrier, roof box or ski holder mounts onto. If your car has no bars, this is the first purchase and the carrier is the second.

What are open roof rails?

Rails running front to back with a gap underneath, so a bar clamp can pass around them. Flush rails sit tight against the roof and need a different fitting; a bare roof needs another again.

Our score

8.1/ 10

The honest inclusion in a roof rack comparison: the bars are usually the bigger purchase, and this is a well-rated set for open rails.
