panniers and underseat bags
Just spent a few weeks touring with my new Quest 2.0. I'm planning on writing a full review, but some quick comments on racks, panniers, and bags:
The default Quest rack is OK for rack-top bags (I assume), but I needed to mount panniers, so I replaced it with a seatpost rack.
Axiom makes a solid one that holds a lot of weight, but it probably wouldn't have fit into the suitcase for travelling.
I ended up buying the Topeak MTX rack with optional sideframe, like fatall showed earlier in this thread. It seems very well made, with good attention to detail. Holds 20 lbs, which is enough for my minimalist style of touring. And it disassembles to fit into the travel suitcase just fine. The only drawback is that the panniers sit well back on the bike, behind the rear axle. I didn't notice any handling problems, but I'd rather have the weight between the wheels if possible.
Ideally, I'd like to have large bags that mounted under/behind the seat, like the Radical Design bike bags. But they're very expensive, so I'm going to play around with various duffle bags and see if I can use velcro straps or something similar to sling them behind the seat somehow.
For small stuff or heavy stuff (e.g. tools, food, wallet, etc.), I bought 2 large waist packs from a camping store ($10 each), and strapped them under the seat, one on each side. This worked out really well - cheap and effective. I leave them on the bike permanently (i.e. even when I'm not touring) as my utility bags. Bonus is that, off the bike, I can wear them on my waist if the need arises.
Will upload some pics when I write my review. Cheers!
