    I spend a lot of time in the big ring(When I'm fit), but think I'm pretty good at selecting the right ratio. Maybe some of the teeth are supposed to be pre curved for shifting or something, because overall it looks pretty good. It certainly shifts like buttah.:deal Chains are easier to find anyway...

    Modolo. Sez so right on the left shifter body.

    I did 3:23 on the mtn bike today. B was riding his fixed gear so I tried to keep it in roughly the same gear he was in. Tough when he's on a 29er and I'm not. :nod I was either half a gear too low or half a gear too high. Legs are toast. Again.

    Getting ready to ride my brand spankin new HTC One X fell out of my pocket. Guess who's got a no-longer-brand-spankin-new phone? You know... the one with all the glass on the front that's now shattered! Yeah. Fun stuff. :bluduh

    Some teeth are shaped different than others, to help pull the chain up onto the big ring. I doubt they're actually hooked, but, probably machined/twisted. Look to see if those oddball teeth are located adjacent to the pins/ramps on the backside of the big ring. If so, then, you know they're supposed to be shaped that way.

    Notice the shape of those teeth by the pins and ramps?

    also note there's a few variations on this theme, depending on who made the crankset/chainrings and when.

    I took a better look, and there is plenty of meat on the teeth. I replace chains every 3-4,000 miles, so it's not a worn chain that would be doing it. I'll ride a few thousand more, then check it out. I'd still like to find a spare ring, just to have it ready. 7700 stuff is getting scarce.

    Clement tires made in Thailand... Wtf. I used Clement and Tubasti-- anyone remember that stuff? Everyone called it tubastige but it did a good job. I just thought Clement left a better base for changing a tire on the road and a better base for future installs.

    There's been a few studies done over the years on tubular glue. Vittoria Mastik 1 always tops the list with Conti's glue coming in a close second.

    Buddy of mine gave me a pot of the Vittoria glue before the season started. I've already used half of it!

    No weenie little tubes for THIS cyclocrosser! :nono

    I'm not really digging the FSA crankset for a number of reasons. But I'm not terrible fond of the Dura-Ace crankset, either.

    Can a person fit-- if he can find-- a 10 speed Campagnolo crankset to a Dura Ace 7900 gruppo?

    What about a Campagnolo 11 speed crankset?

    If it's more of a hassle than it's worth I will simply buy a Dura Ace crankset and get on with it, save the Campagnolo for the next build.

    Cranks are cranks are cranks. Run whatever it is you want. :nod

    IOW the chain don't care whether its running on Campag or Shimano or SRAM rings. :nah You *may* have to adjust your front der. but that's a minor thing comparatively.

    Now, if you're running BB30, Shimano don't make any and I don't remember off the top of the head whether Campag does either.

    You're better off with something like the C-dale cranks or something that don't require an adaptor.

    Watched those last year. :thumb Looks like fun, but Ed Sanders has been rescheduled to the same weekend and is MUCH much closer.

    Headed to Luray tomorrow. Last race of the season is Ed Sanders next weekend. I signed up early and got a good starting spot at Ed Sanders. I ain't gonna miss it! :nono

    so I just mounted some Vittoria Hyper Randonneur tires on my hybrid, in 700x32. test ride around driveway says, SWEET. highly reflective stripe on sidewalls, which I think is a great feature for any tire used on the road. they went on my rims rather easily, no hassles at all stretching them over the rims, unlike the last couple Continental Gators I've mounted (admittedly on a completely different bike).

    these replaced the servicable but rather leaden Specialized Nimbus that came on the bike in 700x35.

    Well that sucked out loud. Luray CX = DNF

    Got about a third of a lap in on the greasy, muddy lots of off-camber corner course, hit a course marking pole, endo-ed, hit on my left side (wrist, elbow, then head) and somehow ended up with my chainring prints and a hole in the skin on my left shin. :confused

    It was at that point that I said 'screw this.' :nod

    Rode all but the start/finish hill and pulled off the course. Brain wasn't in it any more and JRA on a cross course isn't my idea of a good time. Especially when traction is at a premium.

    :bluduh

    The goal of the day was 'work on my starts.' Didn't even do that properly.

    Next weekend is the last race of my season. One DNF is one too many, but if I can learn something from this, I'm still ahead of the game.

    In that regard: Mud tires. No matter what they say Conti 'Mud' tires aren't. :nono I was also told they need to be run at super-low pressures to get the best traction. Inadvertently, I'd been doing just that. Today? More pressure. Co-inky-dink? :dunno

    Don't do a big week mileage-wise before racing on Sunday and expect to do well. Along the same lines, if you're supposed to be on a rest week, take the damn rest week. Don't push on just cause its 70 and sunny in Dec. (Prolly won't listen to this one, but it needs to be said)

    Pre-ride the course better. Easy lap. Hard lap. It does make a difference. IOW get to the race earlier.

    I've narrowed it down to 'earth'. Or 'Baltimore'.
    I have never had any luck with conti's. I think they suck.

    Conti Mud aka Grifo 2 do fairly well in everything but but mud. Keep the pressures low

    for fatter hybrid bike tires, I took my first ride on these hyper radonneurs in 700x32, replacing Nimbus 700x35 (and I had Nimbus Amradillo 700x38 on my homebrew bike before that). They feel much faster and not as mushy, even tho the pressure (70 psi) was about the same...

    I and took them for a brisk 15 mile loop. was riding a good 3-4 MPH faster than I was a few weeks ago on this same loop, mostly 16-18mph indicated on my bikemeter.

    oh yeah, I have to reset my bike meter for the smaller tires. hmmmmm.

    Lots of toys out today, '60's Ferraris, Lotus 7 (Catheram?) and the usual flock of Ducks.

    In house/apartment storage ideas??

    I have three motorcycles, but they take up all the space I have in my shed. No garage sadly.

    I have a spare bedroom, affectionately named the " junk room", which serves as tool storage, motorcycle gear and parts storage, and occasional work shop. That is where I keep the new mountain bike as well.

    It is a bit of a PIA to wheel it in and out every time I need more space in there.

    Any good storage ideas/gizmo's? pics/links appreciated.
