Went over that spillway a couple of Sundays back. Schwalbe land cruisers 35 mm on front 40mm on back because Harfords. Was fine but my pal on his road bike dismounted. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=21487#post-374002 Tue, 12 Mar 2024 15:37:27 +0000 Dave 374002@http://citycyclingedinburgh.info/bbpress/ <p>At the weekend I got a pinch flat on an undropped kerb at Asda Chesser. Annoying but who can say when the tyre was last pumped up, not a bike I've been using much.</p> <p>Yesterday, just west of the Almond aqueduct there's a spillway on the towpath which has a lot of hard stone edges, but I've never had much bother with. In hindsight I was always riding our ebike with "summer" tyres (Big Apples). On yesterday's commute it had ~32mm Marathon Winters on, freshly pumped up, and I got an immediate pinch flat :(</p> <p>On the way home I was extra careful on that bit, then got a pinch flat crossing the watercourse on the way up Donkey Lane! (My little portable pump doesn't have a gauge so possibly not mega hard at that point.)</p> <p>That's three pinch flats in three rides! That bike last had a flat in April '23 (a thorn) and before that twice in winter '22 (a thorn, and something unknown on the road in Kirknewton)</p> <p>Time to put the fat summer tyre back on. I apologise in advance for the snow and ice storms this will cause! </p>
