I was commuting to work along Melville Drive (West-&gt;East) and took my usual right turn at Argyle Place, which involves using a short tarmacced desire line that runs diagonally, joining the junction to the main shared use path that runs parallel to Melville Drive between the drive and Fingal Place / Rillbank Crescent. It was on that short tarmac strip that I took a tumble. No evidence of the tell-tale diesel sheen when I looked at the offending surface... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=13831#post-170605 Mon, 03 Nov 2014 11:07:10 +0000 I were right about that saddle 170605@http://citycyclingedinburgh.info/bbpress/ <p>Mystery falls are generally well correlated with spillages of diesel. Entry/exit to roundabouts near filling stations always worth a close look.</p> <p>Freshly dieseled tarmac has about the same grip as polished ice. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=13831#post-170589 Mon, 03 Nov 2014 00:13:37 +0000 Its_Me_Knees 170589@http://citycyclingedinburgh.info/bbpress/ <p>I think Conti T&amp;Cs put substantially more rubber on the road compared to the Schwalbes. That dodgy centre ridge is, I think, intended to keep the contact area to the same as one might get from a slick road tyre, and hence keep the rolling resistance low. But it's also supposed to impart some extra grip by virtue of the zig-zag and some satellite knobbles if the bike leans over. Not convinced that any of that theory works in practise though... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=13831#post-170564 Sun, 02 Nov 2014 15:14:01 +0000 RJ 170564@http://citycyclingedinburgh.info/bbpress/ <p>Nope - standard M+ on the fair weather bike, spiky Marathons on the winter hack.</p> <p>That wobbly centre ridge looks well dodgy to me. Superficially it reminds me of Conti's old Town and Country tyre, but on those the central ridge looked more "stable". They certainly rode OK. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=13831#post-170553 Sun, 02 Nov 2014 01:28:46 +0000 Its_Me_Knees 170553@http://citycyclingedinburgh.info/bbpress/ <p>I wonder if anyone else on CCE uses these tyres?</p> <p><a href="http://www.southwatercycles.com/smsimg/172/46986-60236-main-71sfsgadovl-172.jpg">Marathon London ATB</a></p> <p>I have them on my ATB that I use to commute. I generally like Schwalbe tyres but these tyres seem to me to be oddly twitchy for a fat-ish ATB-for-urban-use tyre. Yesterday on my run to work my front wheel went sideways from underneath me at low speed, when I was neither braking nor accelerating nor turning. I wound up on the deck having a stare-off with the tarmac. There were wet leaves around but I don't think they were responsible either. My hunch is that the zig-zag centre tread on these tyres predisposes the wheel to slide to one side or another, more so maybe at less-than-average speeds. It may be academic because I think these tyres were a 'limited edition' but I just wondered if anyone else had used them and had similar issues... </p>
