[Closed] Bike Roof Rack BMW 1 Series 2013 (2 bikes)

Why would you want it to NOT touch the frame?

From an engineering perspective, rigidly constraining the wheels and allowing all the mass of the bike to oscillate around the hubs/dropouts doesn't seem like best practice to me...

I was looking at one last month where you take the front wheel off and the forks rest on a bar which locks the bike down.
I have just paid £1600 for my new HT and would like to keep the paint on the frame. Thats why I dont want a rack that clamps the frame and rubs the paint away.
if you know of any please let me know.

I'd just place Helicopter Tape in the area where the clamp touches the frame...

...but if you're committed to this course, the Thule 561 will do what you're asking.

Cheers ill have a look.

Thule 561 carriers are what you seek - fit all Thule bars. They are fork mount and you can stow the front wheel in the car or buy a front wheel carrier (which is QR only).

Fork mounted, the bikes sit lower and much more securely. I went this way as the normal frame-clamp mounts are not recommended for carbon, and I wanted the most secure mount. The only downside is the silly price for the 15mm adapter and the fact you can only lock the bikes in place with QR.

The bikes weight and yours oscillates around the hubs far more violently when riding...

Not even close to the truth, but hey, what do I know...?

Apart from thule there must be other makers of roof rack which are so much off an exspense. I was talking to a company the other week but cant find the website.(yet)!

Same car but I was considering this;

About £200.

Thule 561

Perhaps Daffy could enlighten us as to what is wrong with fork mount carriers other than that they seem wrong to his brain? Maybe he could let all the pro tdf teams and so on know as well since they use them?

On a 561 the rear wheel is retained the same way as other, upright, Thule carriers. The fork clamps in the same way as on the hub and the mount has a fair degree of play built into it - the axle is designed to move. Especially with 15mm it feels and looks very secure, when I see upright carriers on the road the bikes are often flapping about all over the place and they sit very very high.

Surely more down to preference than bikes exploding into balls of flame if fork mounted...

Great if you want no paint on your boot lid and bike frames.
I like the paint work on my frame especially at £1600.

Mite try the 561!

I think some fork manufacturers advise against this type or rack and (iirc) some such as pace state it invalidates the warranty. Worth checking your warranty small print.

I'd rather my bike be held by the frame and prefer tow bar mounted racks but different strokes etc

So, let me get this right.

You have a £1600 HT that you wish to transport on the roof of your car with the cheapest carrier you can get that wont mark the paint on your bike as you don't like the idea of helitape?

You then get appropriate advice and suggestions on this, your first enquiry on the matter. Ignoring this, you then appear together quite arsey with your second request for information.

You will go far my son.

🙄

suspect the best solution here to keep the 1600 quid bike and brand new repmobile unmarked would be to fill a transit with polystyrene balls and place bike inside.

and not to ride it at all.

Well for one thing, when you're riding there isn't much latteral force on the dropouts as the pivot point is round the edge of the tyre. So I doubt the engineer designed for the pivot point to be round the fork dropouts....

Thule are expensive but will be one of the only things to survive a nuclear holocaust along with cockroaches. They are actually reasonably priced compared with other kit out there of similar quality. I've bought cheap racks and bars before and always regretted it.

Fork mounted racks work fine, but maybe I'm lazy but I have an aversion to having to dismantle my bike, I appreciate others don't have a problem with this though. For me the 591 is the best and most convenient option with helitape on the contact points if that bothers you. For me, unless you need the security, it is preferable to putting the bike in the car as you cannot avoid shitting up your car if you do this regularly. Once or twice in a blue moon it's fine, but two or three times a week it gets a bit tedious and shits up the interior of your car.

Tow bar ones are the ultimate in my view, but I'm looking at the thick end of £800 to get kitted out with a tow bar and decent 3 or 4 bike rack. That's just too much.

If you haven't the whit to discern the difference between the total duty cycle of a Tour-riders bike(s) and average Joe STWer, I think you might struggle with any answer I might give concerning mass, lateral frequency, and rigid constraints.

...but by all means, knock yourself out.

Some of the fork mount carriers do not act like a QR which applies clamping force evenly to both drop outs so the slight difference means one can take the majority of the load.

With regards to fork clamp (ignoring uneven clamping) compared to the forces riding a bike the boundary conditions are not the same. When someone is riding the bike there is a lot more freedom to move. The reaction force to keep a bike upright is from the balance of the rider. The loading through the wheel hub is affected by the spokes, rim and tyre flex.

But that said, I am pretty sure that the fork mount carriers are absolutely fine in any normal conditions.
