MTX Trunkbag Cycling bag question

Tallon

Hey guys, have a bit of an issue. I bought this today, but it's the wrong size for my bike in fact, it's tiny, I don't understand what bike it would fit on



I think this is the one I need:




I got the MTX trunkbag with it, and it's fine, but I need the other frame.




Is there anywhere in Ireland, or Dublin I could bring this and trade it in towards the other one? I can buy it online from Here but I don't want to have the spare frame sitting here doing nothing...


Help

Just sell it here or on adverts. A shop won't give you much (if anything) for it.


EDit: What's so small about it?? the clamp? or the platform?

Tallon

The height, Its no where near the frame

petethedrummer

I can't visualise what you mean. What's not near the frame?

Tallon

The legs so to speak, look at the height of the first picture and the difference in the second one

The rack you bought is only meant to be attached to a seatpost - it doesn't attach to mudguard or rack eyelets at the rear dropouts.

Still not sure what ur talking about. Those 'legs' aren't supposed to touch the frame. They just float in the air. The rack just clamps to the seatpost, thats the only contact point with the bike.

It fits this full sized mountain bike.

It was bought for me....

@petethedrummer: Ah, I may be an idiot then.. So it actually supports the whole weight of the bag?

Yes. I'm not sure I'd attach it to a carbon seatpost, if that's what you have.

A regular rack would be more stable as the bags would be lower down. The lower down the weight the better. You might be able to sell it to someone whose bike doesn't have rack mounts.

Tallon

Thanks guys, I'll try that later...

So the second one would be better you think?

petethedrummer

The full rack would be better, but the first one might do the job. It also looks much quicker to put on and take off. It depends on your needs I suppose.

Are you touring or just moving clothes to and from work?

Tallon

The plan is to commute, I suppose I could invest in a better rack later on... It actually seems pretty rigid on, makes the bike feel very heavy too....

Looks very close to the saddle, dying to see what it's like to ride! What do you think?

petethedrummer

If it were me, I'd pack the side bags first with the heaviest items down low. You'll probably notice the handling changes considerably (for the worse), especially when out of the saddle. I had a large seatpost mounted carradice bag that was high up and I hated the feel. Switching to a regular rack allows me to carry way more with less impact on handling. You might not notice though.

The only good thing about carrying a weight on your commute is that the bike will feel super light and stiff when you cycle unloaded at the weekend.

That looks too high for my liking.
How do you not catch your leg in the bag when swinging over the saddle?
I'd prefer to have a lower centre of gravity on the bags as well, stops the bike trying to tip over.
Finally, a general observation; it appears to me that either your saddle is too low, or your bike is too big for you; the saddle-pedal distance looks very small compared to the saddle-handlebar distance. Of course you may be correctly proportioned for that setup, but it looks wrong to me.

Topeak do two ranges of beam racks:

MTX = MTB
RX = Road Bike

There doesn't seem to be much in the difference except weight, though I imagine the geometry is different. The MTX would need to be slightly higher to provide clearance for rear suspension, and so forth.

The height isn't that important tbh. You'll just have to get used to climbing on/off by throwing one leg over the top tube.

They're really commuter racks for people who use their "good" bike for commuting and don't want the hassle of removing a rack when they go out for proper spins. That's why the bags appear so small.

As pete says, try to put most of the weight in the side bags, down low.

i'll buy the bag off you if you can do a decent price, have the rack already
