    I've been getting to know the Vaya a bit over the last month, not as much as I should have, but I kept getting sidetracked by work, weather, family, beer, and general laziness. I've taken it on everything from smooth, wide-shouldered asphalt to busted up, narrow two lane asphalt to gravel roads to paved paths to (briefly) singletrack trails. All this from pedaling right out of my driveway!

    Probably my favorite thing about this bike is the ability to turn down any road and not worry about what I'll encounter. Before, on my road bike, I'd take one of maybe three general loops and either expand it or shorten it depending on how far I wanted to go. Now, using gravel roads or paved trails as connectors, I have a much wider range for ride routing. Not that I couldn't have ridden these things on my road bike, but they wouldn't be very enjoyable.

    The Vaya is not a mountain bike. At least not with the stock gearing. It could take smooth flowing trails ok, but once it gets technical or steep, it's out it's element. It's also a little slow handling because of the stretched out geometry, but the Vaya does, however, love gravel roads. On my road bike, on gravel, I'd be stressed out, preloading my pedals so I could unclip as soon I felt the front starting to wash out. With the Vaya you can just motor along, it's actually probably more fun on gravel than on pavement.

    The Vaya is also very comfortable. Before, my lower back would start nagging about an hour into a ride. Nothing like that so far on rides nearing two hours, except when I was wearing a backpack on one ride.

    I'm getting used to the Sram shifters, but they still don't always downshift precisely, it could be they need a some adjusting with @ 180 miles on so far.

    I'd like to put on some slightly narrower tires, but I don't want to lose any of the stability on gravel. These tires are labeled 28x1.6, Salsa's website lists them as 700x42, I'm thinking about going with something like 700x35. Any thoughts on this?

    my experience with wide 700c tires is, they vary a lot. I had some michelin 700x40's that flat out wouldn't fit in my newer frame, yet some tom slick 700x38 (no longer available) that fit easily, and I just replaced those tom slick with some specialized nimbus 700x38 that are much wider but just barely fit.

    look on the tire for a molded "42-622" or similar. thats the tires *real* ISO size (622mm is the actual bead size of a 700c wheel). Those Michelin 700x40 said they were 42-622 and not 40-622

    I think the next size below 38 thats common is 32, i haven't seen many 35's. then 28, then skinny roadbike sizes like 25, 23, 21.

    maybe I'm late, but I just caught this on the documentary channel the other night, and found it worth watching. I think you can also rent it on youtube.

    Ok, thanks for explaining that.

    These are some of the tires I was specifically looking at:
    http://www.universalcycles.com/shopping/product_details.php?id=41259&category=782

    They say 700x35, but I guess w/o actually looking at the tire you can't really tell...

    Not sure if going to a 38 would be worth it. I'll have to go to some shops and look tires mounted on bikes to get an idea of the different sizes.

    oddly, the manufacturer of said tires doesn't list a x35. they have a 37-622 aka 28x1.40.

    :huh Whomever does their tire sizing/listing needs to lay off :loaded
    I just browsed a couple other tires they offer, and that same 37-622 is also a 700x35 on another model. I mean, WTF? Seriously, this kind of shit is aggravating as hell. :baldy

    like I said, I had some Michelin City "700x40" that were 42-622 which is 700x42. wtf?!? :dunno

    I do wish bike tire makers would give numbers like actual diameter, and sidewall width at a nominal pressure on a nominal rim width suited to the size tire, the way car tire makers have to legally. :puke1

    If you don't mind making your way up to the cities, we have some VERY knowledgeable people in the local shops. The Hub, or Freewheel, to name a couple.... Pick their brain for actual sizes of tires.

    Yeah, it would make things simpler for everyone.

    I got this last bike from Freewheel in the Cedar/Riverside area. When I take it back for a tune-up, I'll see what they have to say about tires.

    does anyone have any advice on straightening a rear steel dropout? I have one that is slightly tweaked and won't allow the wheel to sit straight. I know there's a Park deraileur alignment tool, but I don't want to throw down a few hundred just for a one off issue.

    the local bike shops sell a lot in the $3k and up range and can't be bothered to help.

    Thanks for any info!

    Good shop. Make sure you do it on a non-busy day. You will get more attention that way.

    I've had minor success with my bench vise and some soft jaw covers, or sandwiched between thin pieces of soft wood to protect the frame. Just have to know your strength, use a little leverage in the right place and it should come out fine. I would not do it on an aluminum frame, but steel is much easier to work with.

    large crescent wrench, and eyeball it. use the wheel to verify its close.

    if the wheel is cocked up by the bottom bracket, you may need to tweak the rear triangles, sheldonbrown.com has a page showing how to 'cold set' a steel frame with a sturdy 2x4, and verify alignment with a string... works well enough. I'd verify the string alignment of the rear triangles (and the spacing between the dropouts), THEN use the crescent wrench method to make them eyeball parallel such that the wheel axle nuts sit squarely.

    Those are nice tires but 890 grams is a lot of weight. :eek1

    Check out these tires from specialized: Nearly half the weight, Armadillo casing, and 120tpi for a great ride.

    You dont need tread to ride crushed limestone trails.

    Yeah, those all look pretty good. It would be nice to lose a little weight, too. I don't really ride crushed Limestone paths much, but I've been riding graded dirt/gravel roads. I don't need much tread, but some tread would be nice if the road turns a little mucky. I should probably just run the tires that are on it now for the summer, they're not bad, just a little wide...

    NoVA for now...
    3-ish hours on the bike today. Say -ish cause about halfway thru, my #$%# computer decides to try and re-set itself and goes to the 'choose a language' screen. Since I haven't been able to figger out HowTF to get out of it (the 'set' button ain't setting shit) I lost the first half of the ride. Normally that wouldn't be too much of an issue, but I was in the middle of 2on/2off intervals!

    Recovered from those and did ~30min of 34-ish kph tempo into a sidewind.

    Legs feel dead. Good thing tomorrow's UW Hockey then a day or two of easier rides!

    Ooof... my legs are tingling and cussing me right now. Early summer century with the club turned into a 112 mile sufferfest with me playing the part of point man/local sap dumb enough to pull all the whiners so they don't get lost. :baldy

    19.6mph average with a normalized power of 242 watts. I'm a dumbass of epic proportions for pushing that hard in this heat. Lost almost 6 pounds post-ride. Luckily there is a beer-n-food festival in Durham I'm attending with friends later. Nap time, then back to it... :freaky
