CRUZ 120cm OptiPLUS ST roof bars with kit 5773

The new CRUZ OptiPLUS roof bar system is superb - it's good looking, strong (the load limit is 75kg, depending on the vehicle), easy to use, and the same roof bar feet are used for almost all cars made since 2005 (excluding cars with raised roof rails). Chances are that, if you buy into this system, you'll only need to spend £20 (flush rail kits are £25) on a new fitting kit when you change your car.

You need to order two components: (1) a pair of steel or aluminium bars and (2) a vehicle specific fitting kit to join the bars to the roof. The CRUZ standard size 32mm x 22mm plastic-covered rustproofed steel bars and the fitting kit have been pre-ticked in the list below.

CRUZ Airo aluminium bars option: CRUZ Airo low noise, low drag aerofoil-shaped aluminium bars are available as an option:

  • To our knowledge these are the only low noise bars available in this price range. Aerofoil shaped roof bars were developed by Whispbar and are now also used by Thule, increasingly by Atera, and now also by CRUZ!
  • The reduced drag means that fuel consumption will also be lower
  • 80mm wide x 28mm deep
  • The T-track adapters used in the slots in the tops of the bars are the standard 20mm x 20mm ones - all the products we sell use this size
  • There are black rubber strips to push back into the T-track slots when there's nothing fitted to them
  • These fully anodized bars even have aluminium coloured rubber infill for the slot in the bottom of the bar - a really nice touch!

Please note that the aluminium bar fitting instructions shown on the Fitting instructions tab are for the older style bars, not the Airo. Airo instructions to follow ASAP.

To order Airo bars, untick the steel bars and choose the "CRUZ Airo bars". Note that you still need to order the fitting kit!

Locks are available as an accessory for both steel bars and aluminium bars; they are also very well priced.

All CRUZ roof bar systems are fully T‹V approved and have a 2 year guarantee.

Please note that CRUZ adapter kits will only work with CRUZ roof bars.

Cruzber is Spainís largest roof bar and roof rack manufacturer, founded in 1963. It sells most of its products under the CRUZ brand label, operating from over 50,000 square feet of modern premises and using state of the art manufacturing machinery. Cruzber is highly regarded in the European market in particular and is also Thule's Spanish distributor. We have no doubt that CRUZ branded roof bars are the best made and overall best value in the mid market.

Had no problems and easy to use.

When I bought a new car I had to replace the roof bars and it is great to have a set of roof bars that fit easily and securely. The free locks allow me to leave the bars and roofbox securely attached.

About our reviews:

We test, and often use personally, almost all the products we sell, and we stand behind our comments and recommendations unless customers convince us they need changing. Our Customer Services and Workshop staff also have input into our recommendations.

But it's because we've learned a lot over many years that customer feedback is so important. Fresh, first time out opinions are the most useful ones, and in any event we certainly don't have access to the full range of vehicles that our customers have between them.

Product feedback from existing customers helps our new customers make choices, and also helps our suppliers with their product development.

We e-mail our customers a week or so after their order arrives and invite them to send in a review.

Some reviews are suitable for multiple products. Where appropriate we may, for example, use the same review for a number of different roof bar products where the only difference is the length of the roof bar.

The aim of this note is to persuade you that kayaks should always be tied to the carrying vehicle at both bow and stern.

Untied kayaks have, in our experience, the greatest potential for a roof bar or kayak carrier failure. The massive forces that untied kayaks can generate have even been known to snap roof bar fixing bolts with the result that a complete assembly of roof bars and kayaks has ended up on the road. We know that this has happened with almost every brand of roof bar, and regardless of whether the kayaks are on a special carrier or just strapped to the bars.

You need to fix bow and stern lines, probably using the front and rear screw-in towing eyes to get strong and accessible fixing points on the vehicle. Kayak shops should be able to provide suitable 'paracord' for this purpose. It is cheap and readily available online. Alternatively, Thule makes the QuickDraw 838 which we have listed together with every kayak carrier we sell.

Please note that kayaks should be strapped to the roof bars, or to kayak carriers, using straps that are suitable for the purpose, e.g. 25mm polypropylene straps with strong buckles. Bungee cords must never be used.

Please also note that all roof bar instructions point out the dangers of carrying unsecured long items, as of course do all kayak carrier instructions.

If you tie down your kayaks you almost certainly won't experience a product failure. If you don't you may or may not get away with it. If there is a disaster and the kayaks end up on the road, separated from the vehicle, then you were not using tie downs and you have subjected the roof bars to forces for which they were not designed. The costs of sorting this out are yours, not ours, and you may also have difficulties with your insurers.

We're sorry to be so firm about this, but "things coming off the tops of cars" is the stuff of nightmares, and we want to do all we can to prevent accidents of this sort from happening.

Delivery charges and arrangements:

We charge a contribution towards delivery costs, depending on what you order, where you live, and how quickly you want the goods.

For most UK addresses, the charge for our two to three day service is £5.50 (£9.50 for orders including a roof box) and our charge for Next Working Day deliveries is £8.50 (£12.50 for orders involving a roof box). AutoSock, shoe chains, RUD i-Sock, and small spare parts, are charged £3.95 (Royal Mail Tracked), £4.95 (Royal Mail Express Tracked) or £5.95 (express courier, usually Next Working Day).

There are different charges for any delivery including a sea crossing, and deliveries to Skye - we will contact you with a quote on receipt of order.

Orders for Next Working Day delivery need to be received by 4.00pm.

There are no deliveries on Saturdays, Sundays or Bank Holidays, except for postable items where Royal Mail has a Saturday delivery. Next Working Day orders placed on a Friday will be delivered on the Monday, Next Working Day orders placed on a Saturday will be delivered on the Tuesday.

We are very flexible with our deliveries and will aim to deliver on a day and at an address which suits you. Goods can usually be left without signature - we prefer this with roof boxes. There's a "Special Delivery Instructions" box in the checkout area where we'll ask you to choose a typical instruction and then amend it to suit your particular requirements.

No retailer or courier company can ever "guarantee" a Next Working Day delivery. All courier companies occasionally have the same transport problems as can happen to everyone else, including snow blocked roads, closed roads, traffic jams, mechanical breakdown, an inability to find the delivery address, or to gain access to it if, for example, it's in a block of flats. We work with some of the best couriers in the business, and overall they provide an outstanding service.

Payment options:

We take the following cards, and also PayPal. Please note that the entry on your card statement will be from "The Roof Box Company".
