I found out my donor was a 12-23, I have strong legs though and was able to endure, but a 12-27 would have been much better, I am changing the cassette soon, so I'll have a 30 granny up front and a 12-27 in the rear.
Downhill was definitely a blast, my downhill speed was quicker than the uprights I'm guessing because I'm able to cut thru the air better in the recumbent setting. Comfort was awesome, doing 60+ mile days back to back with nothing hurting was the reason I bought the Silvio in the first place.
The kayak is a 2 person kayak, seat can slide forward if two adults. I just borrowed it from my friend Elias so I have no clue as to the make/model, its a flat bottom and is alot of work to keep it going straight especially if the wind is blowing. Looks like I have another Kayak trip at the start of June, on the Red River, a few of the other paddlers have offered to lend me one of their 14-16ft single person kayaks that will be faster and track better.
