So I swapped out the Nano 40s for some GravelKing 43s. I wasn't sure they'd fit, guessed the front would be ok because the SKS Speedrockers front guard doesn't go under the fork bridge. But the rear seat stay bridge always looked tight with mudguards. Well it fitted fine. Maybe the tyres, which are definitely chunky and wider then the nanos, are not taller. Anyway I was delighted. I'd been thinking for a while of getting 650B wheels, but bluntly the costs and hassle were putting me off. Though thanks to e levity's brilliant looking 650B "Gravel Queen" which showed that the Vado SL could indeed do rough stuff, and recently on this thread AdmChr's beautiful yellow number with Pirelli Cinturato Gravel H 700x42c really inspired me, so figured it was worth revisiting, even if I had to dump the mudguards for the summer. Result.
Thing is I ride back roads, farm lanes, narrow Devon lanes and off-road on ancient bridleways and forestry trails. A mix and match as I trundle around Dartmoor. It's probably 70% tarmac, but as DiggyGun mentioned, in UK the roads seem to getting shockingly bad, and these remote farm lanes are covered in potholes and granite sand (or mud in winter) with frequent flooding. But they are fun fun fun with very few cars.
I need a Land Rover but I was never drawn to the full fat big motor e bikes, loving the Vado SL's speed, lightness, nippiness and of course the main point is for me to get fit and over the last year and a half the bike has really helped.
I've only done 2 rides (11 miles & 26) on the panaracers but Jesus Christ Almighty these tyres make a huge difference. I think it tips the bike over from capable road bike to MTB. The tyres create that downhill fast confidence like I was on my mtb. It feels fast and bombs along.
On the flats and particularly on smooth tarmac it's fine and feels fast - might be a bit sluggish on long straights in comparison to the Nanos, but not so I'm bothered or (so far) have noticed much. I have relatively few smooth flat roads anyway and I tend to cycle alone so I'm not needing to keep up with a fast paced chain gang for instance.
It's early days but I'm really excited by these tyres and the difference they have made to the Vado SL. The 25 miler I rode the other day was a typical loop with steep climbs and descents and a couple of 20% bridleway descents that where total rock gardens and yet the bike felt so comfortable heading down. Though if I do much more of that kind of thing I'll need a dropper post! And more brake pads.
I'll report back after a month or so. It's like having a new bike.
