I use an Exped Orion..marvelous tent, two vestibules and not too big. Packed size is 42cm in lenght, but will try and measure the poles length for you. Compact and can be pitched with inner attached so great in the rain.
I sell them but sadly out of stock at present, but they are due in next month (March) along with the rest of the Exped Range.
Its also tall enough for my lank self to sit up in and done bike gear when its wet out or sit in my chair mat and read of an evening. Top tents but then I could be accused of being biased. Before the orion I used a North Face Bull frog, great tent, just not enough space for biker, plus luggage.
safe riding and hope to see you out on the road. .. John..
