NJS of LFGSS

first logical thing JRatNW has ever said. get the first scuff on there early and then you can actually ride the ting.

17t NJS cogs exist and you can find them if you know where to look. Not cheap though.

I just bought that one :/

Let me know what he says though! I trawled through all his stuff a few weeks ago and only found a really worn and slightly rusty sun tour.

What makes 17t NJS cogs so rare?

What makes 17t NJS cogs so rare?

The fact that there are not a lot of them.

i agree. i can just ride it

Where do you get all your knowledge?!

Seriously though: might be because there is not really a use for it? It's not like Keirin racers run those kind of low gears.

Yes, hence the low production numbers, hence the lack of availably and therefore the rarity. But people who what to ride sweet Japanese NJS bikes on the road because they have more money than sense want higher numbers of teeth on their cogs. If they want a truly full NJS build that is.

Reminds me more of beach sand.

I thought especially in Keirin the racers run lower ratios than on the olympic tracks. I don't know much abouth Keirin tough

This is what I found so far:

I tweeted to Perkins and asked him about the gear ratios they use in Keirin racing. His reply: "ratio is between 3.85 up to 4.20!

It's funny you keep tabs on people on a fixed gear forum. I have no idea who you are but I'm SO EXCITED to meet your standards of posting.

Chill. You do post a lot of shite though.

fixed gear and single speed forum

were you aligning saddle angle to bar angle?..

Why do you ask?!

Because it is quite common, if not expected, to have the top side of the saddle aligned horizontally. In most cases, this is the correct fit. Not saying everyone should run their saddle that way, but I do believe huge amount of cyclists, including vast majority of this forum's members, can't be wrong to such extent...

exactly, that's why I was asking in the first place

Whatever! Get a life...

What ever happened to lfgss rep system?..

I've had a break from this forum and now I remember why...

I missed you so much
