Saturday cycle on the coast with friends...



First some geeky bike tyre waffle...
Friday after work i tried some  5" tyres on the Singular Puffin Fatbike as now i have them spare as fitted 4" tyres to my own Surly Wednesday bike,
The Singular Cycles website says that the Puffin has fork clearance for 4.8" tyres and frame clearance for 4.7" tyres, this is correct as i can show you,
I like may have tried to fit the biggest tyres on bikes not designed for them. I know my own Surly Wednesday struggles with the 4.8 Schwalbe Jumbo on the rear and you feel it rubbing the inside of the chain stays when you start throwing the bike about.
The Wednesday`s  spec says it can take up to a 4.6" tyre, but you will find here in the UK it`s not that easy to actually find 4.6" tyres,
There is the 4.6" Dunderbiest tyre  by 45 Nrth if you have a spare £120, cheaper option though is Surly`s `Big Fat Larry`, says 4.7" on the tyre but it sits inbetween most 4" and 5" tyres for size.

The 4.8 JJ is fine on the front...


Fits on the rear but tight...


But its the chain clearance or lack of it in the 3 lowest gears...


Now with the Surly `Big Fat Larry` (BFL) tyre fitted and perfect!...


And that`s  how to go fat on the back for this bike and my Surly Wednesday if you cannot afford/jusify the price of the 45 Nrth tyre...


I`m sure there are other tyres of similar wall hieght and width as the BFL but this will do for me for now to test the bike on real soft sand...

I also rotated the eccentric BB to get the shortest chainline, easy to do as the Surly crank arm is quick to remove with two pinch bolts and the end cap to access with my BB tool. a C spanner version of this tool would make it simpler still no having to remove the crank arm...

I will do another few posts with the bike set up like this next week...

Saturday and a coastride with friends;


Down to North Berwick and met up with Craig, Jason, Brian Mark and Fraser and with a midday high tide and strong wind wich would mean a hard winch west  we rode east to Seacliff and rode what we could of the coast above the high tide line and the woods of Tyninghame before a stop at the ace Tyninghame Cafe.
Not a lot of miles, some real techie rock riding, ace woodland trails, lots of stops to chat and a real fun day...
