Thanks anyway!</p> <p>It was always going to be a bit frankenbike, as I want something really large on the front for the shock absorption Arellcat mentioned. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9292#post-97220 Thu, 17 Jan 2013 13:28:21 +0000 wingpig 97220@http://citycyclingedinburgh.info/bbpress/ <p>Had a look at <a href="http://www.rosebikes.co.uk/article/xtreme-atb-rim-28-sari-t-19-r/aid:46903">rosebikes.co.uk</a>?<br /> Beware the final stages of their delivery process, which seem to unavoidably involve Parcelforce. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9292#post-97211 Thu, 17 Jan 2013 13:04:57 +0000 Arellcat 97211@http://citycyclingedinburgh.info/bbpress/ <p>Uberuce, Joe Murray was doing that with Kona mountain bikes in 1990. Not so much for braking forces as shock absorption and greater control, while saving a bit of weight on the rear tyre. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9292#post-97204 Thu, 17 Jan 2013 12:45:33 +0000 Uberuce 97204@http://citycyclingedinburgh.info/bbpress/ <p>Go full Frankenbike and have a skinnier real wheel?</p> <p>There might even be a real argument for that in a city fat bike. My gut says that since braking force puts weight onto the front wheel and off the back, the benefit of a big bouncy tyre is smaller for the rear. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9292#post-97202 Thu, 17 Jan 2013 12:15:43 +0000 Darkerside 97202@http://citycyclingedinburgh.info/bbpress/ <p>Said table is at the bottom of here:</p> <p><a href="http://sheldonbrown.com/tire-sizing.html#iso" rel="nofollow">http://sheldonbrown.com/tire-sizing.html#iso</a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9292#post-97201 Thu, 17 Jan 2013 12:04:17 +0000 chdot 97201@http://citycyclingedinburgh.info/bbpress/ <p>Lots here (of course) -</p> <p><a href="http://sheldonbrown.com/rim-sizing.html" rel="nofollow">http://sheldonbrown.com/rim-sizing.html</a></p> <p><a href="http://sheldonbrown.com/wheelbuild.html" rel="nofollow">http://sheldonbrown.com/wheelbuild.html</a></p> <p>I saved this a while ago, but couldn't find on SB site just now -</p> <p><a href="http://www.flickr.com/photos/chdot/8389499866/"><img src="http://farm9.staticflickr.com/8510/8389499866_da89eb1f37.jpg"></a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9292#post-97200 Thu, 17 Jan 2013 11:53:57 +0000 chdot 97200@http://citycyclingedinburgh.info/bbpress/ <p>"does that mean what MTB types call 29" is actually 700c?"</p> <p>Yes (as answered above) - of course whether it <em>is</em> 29" - or 26" on 'normal' MTBs - depends on the tyres!</p> <p>And now, the new trendy size is going to be(???) 650B - aka 27 1/2". </p> <p>More than you ever need to know -</p> <p><a href="http://sheldonbrown.com/tire-sizing.html" rel="nofollow">http://sheldonbrown.com/tire-sizing.html</a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9292#post-97198 Thu, 17 Jan 2013 11:42:17 +0000 Darkerside 97198@http://citycyclingedinburgh.info/bbpress/ <p>I'm effectively trying to build this on the cheap:</p> <p><a href="http://surlybikes.com/bikes/krampus" rel="nofollow">http://surlybikes.com/bikes/krampus</a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9292#post-97196 Thu, 17 Jan 2013 11:42:06 +0000 Arellcat 97196@http://citycyclingedinburgh.info/bbpress/ <p>As long as you don't go crazy with your track pump, you can probably squeeze a 55mm tyre onto a A719.

Wonderful, eh?</p> <p>The issue is that most of the wide 29er rims assume you're using disc brakes, and I want canti's because a) I want to be special, 2) I've already ordered a flip/flop hub and iii) I don't need the power of a disc on the rear wheel. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9292#post-97187 Thu, 17 Jan 2013 11:22:41 +0000 Uberuce 97187@http://citycyclingedinburgh.info/bbpress/ <p>n00b question: does that mean what MTB types call 29" is actually 700c? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9292#post-97186 Thu, 17 Jan 2013 11:22:16 +0000 Instography 97186@http://citycyclingedinburgh.info/bbpress/ <p>Wider than something like a Mavic A319 or A719 touring rim? I think those come in 32h flavour and will take tyre up to 38mm (at least that's the fattest I've had on them). A319 is about £20-30 and the A719 about £40-45. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9292#post-97180 Thu, 17 Jan 2013 11:09:40 +0000 Darkerside 97180@http://citycyclingedinburgh.info/bbpress/ <p>Exceptionally dull I know, but anyone got any ideas? Looking for 700C/622/'normal road bike' size, width as much as possible (25mm+), 32 spoke, braking surface.</p> <p>Best I can Google is a 'Velocity Dyad' at 24mm, but can't find any UK stock.</p> <p>Comedy Surly sizes won't work as it's for a rear wheel, and the fatter unicycle rims either have no brake track or are 36+ spokes. Definitely options for the front though.</p> <p>The observant will spot the MonkeyCross concept slowly morphing into a slightly-fat-bike-on-the-cheap... </p>
