Man now that it's warming up I can't wait to get back home this summer and try my hand on Fountainhead's single track again. Definitely want to get in shape this summer.
Question, though: I know a lot of people say don't wear stuff on your back and that's primarily how I get my water (a camelpak). With the intensity of riding for me, what's the best route to go so I can stay as light as possible but have water and also carry my wallet/phone/keys? Do you guys just use a bottle cage and like a small bag attached somewhere to the frame?
Bottle cages with one or two small bottles for me, and rear pockets on my jersey for my valuables. Your jersey choices are a little more limited if you want a zipped pocket, though. You can get bags for the frame as well, though I think they're more common for mountain bikes; I wouldn't put one on my road bike! Some people choose to keep the bottle cage on the seat tube free for a storage bottle to shove some stuff in to, though that'll mean bringing a large single drink bottle if you're someone who needs a lot of liquid.
I'd agree with that, but you didn't do that, you recommended starting to change the bike.
Thomaser asked about knee pain - I commented about similar right knee issues
I had and what had worked to quickly resolve those issues for
me. This is not a recommendation to do anything, it's a suggestion of a possible solution to the problem. Having pain in one knee can point to a problem on that side of the bike, with the cleat on that side being a logically likely culprit.
Though it feels strange to need to explain my post like this; I clearly went on to say "it might be something else for you", and, considering he asked about saddle height, I listed a non-exhaustive list of other possible fit related issues. Being unsure of his saddle height, I suggested a starting point in determining the correct saddle height. Simple really.
