Yeah, I need to HTFU ... and lower my gearing **rolls eyes**

Seriously, I want to race down to the lbs and buy a 19 tooth cog ... only it's a public holiday and they're not open ... and they're 'normal' bike shops and so don't carry track cogs in stock - they're not hard to get, you just won't get one over the counter in most shops. Good thing I'm on holidays this week.
