It's a Burley Bee. No suspension and quite an old version but looks in very good condition. Picking it up tomorrow as been away for the weekend playing.
Mostly it will be used to get to the local caving huts and there are no real hills to those as they are on top the hill and I live in top the hill, and I won't be carting much weight. Particularly after digging trips in caves your equipment is often completely caked in mud and slop to an extent that is difficult to comprehend. Being able to dump it in a big trug and then onto a trailer is so much more convenient than trying to pack it all in panniers as everything else get caked in crap as well and it takes time packing bags = less time in the pub.
The trailer is 8.5 kg, by the time I have stripped off the stuff I don't want and added a light base it's probably not much more than 10kg. The caving kit is probably only about 10kg so that should be very easy to tow. It's only personal kit as the heavy stuff like ropes and ladders are at the huts.
I'm already aiming to lower the gearing and doing a bit of a thermal mod. Probably a dual 34t / 42t chainring with ~30t at the back. The 42 flat chainring is in the post, once I check the chainline, assuming it's ok I'll order a new front derailleur, small chainring and some thermal pads. I think it would be very rare I'll be doing a supermarket run with the trailer, my wife will do the big shop with the car, I just do small shops in-between and panniers are fine for that.
The trailer is just for speed and convenience rather than heavy load carying, but I would find cheap squeaky wheels very annoying. The early Bees only have composite wheels so not sure how string but they can't be too feeble to safely a carry 100lb load of small children which are much more fragile then the stuff I'll be carrying. The wheels do have proper bearings in them.
