I agree with others about chain tension. My guess is that the frame is flexing a tiny bit when you stand on the pedals, increasing the chain tension. To account for it, I’d just need to move the rear wheel forward in the dropout a tiny bit, taking care to make sure it is centered. Did you remove the wheel when you replaced the chain? I’d also check to see if the chainring bolts needed a quarter turn. Your rear cog doesn’t look worn out to me.

Back when my commute was shorter and flatter, as my fixed gear’s chain would wear, I’d bump the wheel back once or twice by a fraction of an inch to maintain chain tension, before finally replacing it. Sounds like you maybe just need to do the opposite, since it’s a new chain.

I had to re position the wheel when I put the new chain on. The old one was stretched to at least 1.0 on the chain checker. Bike was quiet before the new chain and nothing else changed, so it’s gotta be the tension, cog, or chain ring. I made sure to tighten the chain ring bolts before i put on the new chain.

This is the perfect opportunity to initiate the “Stump the Chumps” thread.

Which chump will get the “grinding noise on the fixie” problem right?

set it up and I’ll get some audio/video

Put it in a stand and turn the pedals (carefully! being a fixed gear finger chopper and all). Watch the chain/cog interface.

If it’s not chain tension or imperfect chainring run out, it could be that the chain doesn’t match the slightly longer teeth of a fixed/SS cog. I had this issue once trying to use a Surly cog with a chain made for geared drivetrains. If you’re running 1/8th on both I doubt you’ll have that issue. I run 3/32″ though.

It spun nicely and quietly in the stand.
Using a KMC 1.8″ chain, same model as the one that came off, and matches factory spec too.
Could the cog be super worn out? The chain was at 1.0

possible that the rear wheel is slightly out of alignment?

If it wasn’t so hard for me to do things at last minute’s notice, I’d definitely be in. I am going Friday and Sunday though! Very kind of you to think of us Steve!

I hear Rene Herse makes some pretty good stuff.

Seriously though, it might be worth checking out and meeting up with some of the DC Randonneurs to ask them and see what they have on their bikes.

So is the FCCII caravan now a relic…dead…gone…kaput? Or are there others interested in reviving it? I’ll be at the regular meet-up spot at the WOD and Maple in Vienna tomorrow morning, ready for a prompt 6:30 departure.

I haven’t been able to make the caravan time frame at all in 2016, it’s just too early with my family schedule, and who knows when that will change.

Orange and Silver share the same track between WFC and EFC, so I don’t see how the Silver would be an alternative that would provide a different outcome.

They’re only going to delay the orange trains :p

Are you copying from something like Microsoft Word? If that’s the case, it’s probably mishandling of special characters (the curly quotes that Word does are a common culprit). You hit post, the server tries to save it to the database, and the database freaks out.

sometime excel, although even the strava ride titles and stats wouldn’t post, but they seem to be in a table format.

Is the trail through Oakcrest Park rideable?

It’s narrow, paved, and steep. Would be an interesting diversion from Arlington Ridge. Goat Path, without the bollards. Death is imminent.

@LeprosyStudyGroup 145836 wrote:

That path up to Oakcrest is 1 way traffic width and gets up to like a 20% incline. People walk their dogs on it. It’s a lot of fun if you like that stuff. Most people don’t.
