Time to learn how to lock your bike with a better lock

What frame is that.

P.S Has anyone tried a proxy/anonymizer to circumvent demonoid canadian ip block?

i'm going to the bike show early as i would like to beat the crowds (ha!) and i have to be at work later on so i suggest meeting at moonbeam at 9 sharp (ie no hanging around for too long) and riding down there shortly after for those that are interested.

Yes.



(Someone posted a link to one just a few pages back, check the 30s - I found it the other day).

I might meet you all at Moonbeam, I might not bother heading east and west again, and just head right to the Ex. grounds. I'll be at the show fo' sho'.

www.4proxy.com has been working fine for me on its default settings.

6 degrees?! This is going to suck.

Good news is a tailwind all the way to work.

I was the one that posted that, but 4proxy seems to work the best. A lot of the web based proxy's won't let you log into a site.

Okayguyses, let's have bike talk!

FSA Gossamer compact crank (50/36). It's billed as being 9/10 speed compatible, but in reality in the small ring my last 3 gears are unusable due to the chain rubbing (and at times catching) the big ring next to it. The 9sp chain is slightly too wide to clear the ring next to it. The rest of my drivechain is all 9sp (105 shifters/front derailleur, deore rear derailleur, hg50 cassette) and I can't afford to change that. Soo ... ideas are to try to use some chainring spacers to move the small ring inboard .5mm and see if that helps, or reduce the chain to the minimum length and see if that helps free up things a bit too. The concern is that if I move the chainring inboard too much the chain will drop between the gap and removing links still won't make the whole range available in the back.

Taking a look at where the chain actually rubs/catches ... *looking* ... I'm also thinking this problem might be solved by going down to a smaller big ring. I could use one anyway, but this might just mean the chain rubs on the teeth vs. just below them.

Meh, ideas? I'm off to practice and pick up some spacers at Fur Brain.

Can't you get similar ratios with the big ring and an intermediate cog instead? No cross chaining, no extra effort on your part.

It's not even the cross-chaining. Luckily, I can get the ratios and that's fine. It's that the chain is hooking up on the ring next to it and getting ripped up while the derailleur's still in the other position. I was seeing how far I could push it on the way home and in the least offending cog it'll just make a slight tick at normal riding torque - jump out of the saddle thogh for a sudden sprint and it all goes to hell as the drivetrain flexes. I don't care if I'm rubbing the derailleur (if there's no solution I'll have to get drastic w/ the limit screws) but inadvertently hooking up on the big ring would be hell in a race. If possible, I'd like to be able to have more than 6 usable gears in the back + small ring, so that's the ultimate goal.

I'm not sure I'm following you anymore, but I agree that your drive train messing up while you're trying to sprint would definitely be annoying.

I would space the big ring further outboard rather than small ring inboard. Did the crank/BB come with any spacers for the BB? Manipulation of the BB spacers...like putting an extra .5 on the drive side of the BB might help as well. If you want to get a perfect set-up for cross maybe take the big ring off all together. I have an old 110 modified chainring that I used as a bash guard/ring keeper...you can use it if you like...and put a cateye keeper on the inside. I know you ride this on the street as well but in a cross race there is little likelyhood of even needing the big ring.

Okay, small ring, small cog ... the chain is making contact w/ the ring next to it regardless of where the front derailleur is positioned. There's no adjustment I can make w/ the front derailleur to correct the problem other than adjusting the limit screw to act like an early warning system (so the chain rubs against that before making contact w/ one of the rings). If I do that, I'm still losing 3 out of my 9 gogs in the back. The small ring and smallest 3 gogs are affected by the angle of the chain intersecting with the big ring.

Gold Jerry! Gold!

Ya, I think if I remember where things were set the limit screws "want" to go that way more than inboard anyway. And no spacers, it was pulled from a bike that's been previously cannibalized for parts. Single ring may be an option. No time to worry about it for this weekend, but maybe for next.

So, if you're in the small ring up front and you shift into any of the 3 smallest cogs in the back, that's where you get trouble, right? Since I'm mechanically ********, this might not make any sense, but what if you redished your rear wheel to move the cassette inboard a touch? That might help your overall chainline..?

Obviously you're going to have SOME issues when you're cross-chaining like that, but usually it just results in some derailleur rubbing, not full on engagement on the big ring.

ps. I have a meeting with a client this morning and they actually emailed me to ask me what kind of coffee I prefer.. now that's service! Of course, this guy has been a bit of a pest, so a little sucking up is helpful.

Re-dishing wont have any significant impact. You cant re-dish without losing a spacer from the drive side which would not allow the cassette to be installed without rubbing the frame. If the .5 spacer between the rings doesnt work and spacing the BB outboard a smidge isnt possible than getting rid of the big ring is the best option. Not to dump on DeVinci but seeing as you are using fairly standard components it sounds like a poor frame design.

I kinda liked the 6 degrees this morning..... J...if you want to get there early I would recommend being at the door for 9 9:30...remember the line last year? I can;t see you securing any advantage meeting for coffee at 9.

this is kind of everywhere all of a sudden, but wow.. https://www.youtube.com/watch?v=Wffwg7pA0t8

So you told him whatever kind has a couple of shots of whiskey in it?

Yeah, I say we all skip the pre-show coffee as I mentioned and just show up to the show early. Just scan the line for peeps and if you don't see anyone, stake a claim at the end. As I mentioned before, we could always do a post-blowout show 'n tell.. I vote we go to Manic Coffee for a change as well since they have more space without us having to sit outside.

I'll git you for that Wes, oh yes I will. When you least expect it....

BUM RUSH THE SHOW!!!!

Whats the coffee that some animal ingests the beans and then poops em out? This what you should ask for.
