While I admit, the paint condition is fine, and I don't "need" to spend the money, I just really don't like the paint job. I prefer a more subtle look. And I really like the newer style Kona lettering over what is on it now. So I want a solid color with simple lettering. I can get a chemical strip and powder coat done for $85 here in town, which I don't think is bad at all.
As for the front wheel...I test rode some 29ers and found them to be clumsy for what we have around here. I have a hybrid with 700c wheels, but with road tires and I really like that, but the 29er was more difficult to navigate on trails around here. I test rode a 650B and really liked it. I will primarily be riding on singletrack and forest trails, and the 650B wheel seemed to get through that better than the 26er did...plus I'm not a small guy, so the slightly bigger wheel up front seemed to help.
I plan on spending around $200 for the front combo, and with the new paint and other additions, I'm still under my $800 budget i gave myself...
