I assume modern manufacturers aren't immune from the old practice of designing once and using many times when it comes to creating components. There's perhaps no reason for them to be there for <em>your</em> frame, but if the same tube was used on their other frames, it might not be worth their while to go to the effort of not including the holes on some tubes but including them in others? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=8608#post-86851 Sun, 07 Oct 2012 23:49:06 +0000 Smudge 86851@http://citycyclingedinburgh.info/bbpress/ <p>Could be, though I'd expect race numbers on TCR's rather than the softer OCR's... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=8608#post-86844 Sun, 07 Oct 2012 23:28:57 +0000 crowriver 86844@http://citycyclingedinburgh.info/bbpress/ <p>I suppose they might be called pump pegs rather than nipples. Anyway chsot's photos is pretty conclusive, but that race number mount could be a pump peg too, no? When it's not helping race numbers to stay on (aided by cable ties it seems). </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=8608#post-86836 Sun, 07 Oct 2012 22:53:39 +0000 chdot 86836@http://citycyclingedinburgh.info/bbpress/ <p><a href="http://cdn.mos.bikeradar.com/images/news/2008/07/12/Gilbert_FdJ_Lapierre_number_holder-480-70.jpg" rel="nofollow">http://cdn.mos.bikeradar.com/images/news/2008/07/12/Gilbert_FdJ_Lapierre_number_holder-480-70.jpg</a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=8608#post-86834 Sun, 07 Oct 2012 22:47:14 +0000 kaputnik 86834@http://citycyclingedinburgh.info/bbpress/ <p>Frame pump nipple mount or race number mount.

The Zefal hpx is just a little to short to wedge in as you would a traditional frame, but with a little hook thing attached to that mount...</p> <p>EDIT.

I noticed that underneath the top tube, about an inch back from the head tube, there is a threaded hole in the frame (think the sort of thing that normally comes in pairs so you can mount water bottle cages).<br /> I've had a scratch of my head, pulled out the splinters and still can't work out what it's for, anyone care to enlighten me?<br /> Cheers chaps and chapesses :-) </p>
