No. Please do not attach a child seat to your tubus luggage carrier. Our luggage carriers are extremely resistant to bending and other stresses that occur during travel. However, if attachments such as child seats are attached with crimp clamps, the carrier can break. This is because tubus luggage carriers are made from thin-walled tube. Damage of this kind is not covered by the guarantee.

Please note the following: A child seat that is attached to one of our luggage carriers by means of crimp connectors and the carrying of a person on a luggage carrier in this way invalidates your guarantee coverage and, more importantly, poses a danger to the life and limb of the child or person using it!

Please take a look at the technical drawing for your preferred carrier. This can be found (as a link) in the information on the product in question here on our Website.

The roundstays of the AIRY and LOGO titanium luggage carriers consist of a bendable aluminium alloy, since in many cases, these roundstays must be bent in order to join the luggage carrier to the bike frame. If the roundstays were made from titanium, they would not be bendable.

The clamping parts with which the roundstays are attached to the luggage carrier are made from stainless steel. This is because otherwise, an extremely undesirable electrochemical reaction (contact corrosion) would occur between the aluminium struts and the titanium, which would make the struts brittle.

Yes. The load capacity is max. 25 kg if the carrier is attached to the quick-release axle, even if a higher capacity is stated for the luggage carrier itself.

Naturally, if a lower capacity is specified for the luggage carrier, this capacity cannot be exceeded with the quick-release adapter set, either.

Simply take a strip of Sellotape or duct tape and stick it on the section of the tube where you want to place the clamp. The ends should overlap slightly. Then mark the place where the ends overlap, remove the strip of tape, and stick it to something flat to measure it. The distance from the start of your strip to your marking is the circumference of your seat stays. You now need to divide the result of your measurement by Pi (3.14 is sufficient!) to find the required clamp diameter. Example: Your strip of tape measures 75.5 mm, so 75.5 ÷ 3.14 = 24.04 mm. So you find the 24–25 mm clamp in the tube clamp range – and off you go!

The spring must already be pretensioned prior to mounting so that it can get a really good grip afterwards. If you're having problems mounting it, your tubus specialist dealer will be pleased to help you. Alternatively, you can send it to us, and we'll deal with it. If you wish to do this, please contact us directly.The spring must already be pretensioned prior to mounting so that it can get a really good grip afterwards.

No, we do not offer a spring flap for this titanium luggage carrier.

The lower hook on the bag must be replaced with the hook for the 16 mm tube (Ortlieb art. no. E110). Your dealer can also get this spare part from us: Art. Nr. 30013.

No, unfortunately that's not possible. At tubus, we supply and support specialist bike dealers as a manufacturer of high-quality components. Please contact your local specialist dealer, who will be able to provide expert help.

All spare parts for your luggage carrier can be delivered to specialist dealers by tubus – including parts for older models. Please just ask, and your specialist dealer will be glad to order the parts you need (if they're not already in stock).

The surface of tubus luggage carriers consists of two layers. The base layer is a cathodic dip coating (CDC) like that used for the underbody parts of cars. In accordance with automotive standards, it can withstand a 400-hour salt spray test, which corresponds to a full lifetime for a car. We also apply an additional polyester layer that can withstand a 500-hour salt spray test.

In combination, these layers provide a surface that is more than twice as resistant to corrosion as an automotive part found on the underside of a vehicle. However, just like other coatings that can be applied to steel parts, this coating cannot withstand the effects of heavy-duty mechanical abrasion like that caused by panniers. Panniers often have highly glass-fibre-reinforced suspension systems. Glass fibres or beads are added to the polyamide plastic to strengthen it.

If there is no unreinforced intermediate part or protector between the hooks and the lower support and attachment parts of the bags and the luggage carrier, significant abrasion is inevitable. Unfortunately, this cannot be prevented by any type of luggage carrier coating.
For information on how you can best protect the surface of your carrier, see the answer to the next question (care and maintenance 02).

Since abrasion can always occur during travel despite our usage of state-of-the-art resistant powder coatings on our luggage carriers (see care and maintenance answer 01), we recommend that you protect your luggage carrier with our abrasion protection set (79006) or protection film set (79005).
In particular, the transparent film (79005) was newly developed in 2018 to meet our requirements and has been tested in harsh conditions in accordance with our standards to ensure its adhesive power, resistance to UV rays, and abrasion resistance. In addition, please always make sure that your bags sit tightly on the carrier. The inner diameter of your bag hooks must be adjusted in line with the tube diameter of our carriers (if necessary using adapter parts that should be provided with the bag). The lower hook should also be as firmly attached as possible to the tube (on the TARA/DUO, an optionally available wider hook can be used due to the 14 mm tube). This is because a bag that is firmly attached cannot move, and will therefore cause less abrasion.

If there are already spots that have been rubbed bare or rusty spots on your luggage carrier, you can simply sand them back with fine sandpaper where necessary (the rust must be removed) and then paint over them with a commercially available touch-up stick (automotive accessory, e.g. black: RAL 9005 matt / silver: RAL 9006 matt).

Please note that a tubus luggage carrier that has bare spots resulting from rubbing bag hooks or their reinforced corners does not constitute cause for a guarantee claim.

Yes. You can choose one of our stainless steel or titanium carriers:
• AIRY
• COSMO
• FLY CLASSIC Edelstahl
• LOGO CLASSIC Edelstahl

The surface of these carriers is blasted but uncoated, and nevertheless rust-proof (Airy) or resistant to rust. This means that there's nothing for bag hooks to abrade. At most, the hooks can minimally change the surface structure of the material, which will hardly be noticed at all.

Please note: Our stainless steel luggage carriers are not rust-proof but are largely resistant to rust. In extreme conditions such as high air humidity, salinity, and chemically aggressive atmospheres, localised flash rust can occur. However, this can be removed using chrome polish.

None of our luggage carriers has ever been sent back to us rusted through. The steel alloy of the chrome molybdenum that we use can rust if there is no surface protection. If the plastic layer on your tubus luggage carrier is damaged down to the steel, however, the tube will not rust through as a result and large parts of the plastic will not flake off.
