These Schwalbe Marathon GT tyres arrived for testing from Schwalbe UK. Ours were the narrower 35mm section- nigh on1.4 inches in old money but there’s an even beefier 38mm, which seem a fitting choice, for the latest generation of disc equipped tourer, or tarmac tamed cross/gravel bikes.
These are much faster than the legendary and justly revered Marathon. Something that is immediately obvious from the first few pedal strokes-they’re also significantly easier to mount-no tyre levers required. Stiffer sidewalls, 7mm and 68g apiece separate them from the generally likeable, uber plush Maxxis Roamer.
Their E-bike compliance is also likely to explain the additional girth, although the Schwalbe inspire greater confidence along the wet, silty lanes. The sort that seem perpetually carpeted in gooey dung, complete with thorny, talon-like hedge clippings.
They use the “Dual Guard” system. Rather than our old friends Kevlar/Aramid, Schwalbe employs a two-layer nylon casing and a further 2.5mm strip of India rubber that works like a trampoline, forcing sharps out, thus minimise the risk of a flat. Schwalbe rate it 6/7 and say it strikes the optimal balance between speed and puncture prevention, which sounds perfect for bikes in daily service.
Talking of which, sidewalls feature a reflective strip and dynamo track, adding to their appeal.
Retro-reflective strip and the Chevron style water channelling grooves are very reminiscent of Vittoria Voyager hyper http://www.sevendaycyclist.com/vittoria-voyager-hyper-tyre .
Interestingly, their profiles are slightly narrower than the faster rolling, Italian brands’ 35mm section, meaning a more comfortable fit in my winter/training fixer’s rear triangle.
Formative impressions are very favourable. 65 miles along greasy/icy back roads suggest a quick, yet ultra dependable tyre. It’ll be at least 400 before I arrive at anything near tangible conclusions.
Meanwhile those slushy lanes see regular post-ride rinse-overs to prevent salty, caustic stuff taking hold and moreover, nibbling away at pretty paintwork and components. I’ve got this down to around 10 minutes, including a quick, precautionary squirt of PTFE based lubes on exposed cables, pivot points and similarly sensitive mechanisms.
I’ve also reverted to the Rock n’ Roll gold lube for more staying prowess but without the stickiness associated with traditional wet lubes.
Decent lights are imperative during the winter months and not just the retina melting type, of which I am so very fond. Often it is the blinkies, retro-reflective and tertiary lighting that first registers on a driver’s radar. Aside from the Visijax gilet (www.visijax.com ), which continues to impress me with its presence, I’ve discovered the origins of John Moss’s preference for yellow, signal yellow to be precise.
Both his Tandem trike and Mango fairing sport this shade. Having recently changed the Velomobile’s gearing for a 2x9, thus improving efficiency overall, he’s decidedly dissatisfied with attempts to repair the scuffed nose using single pack acrylic aerosols. His godson works at the sharp end of car body repair, thus is fully equipped to apply 2K. We’ve tracked down a suitable Ford shade, so watch this space...
Elsewhere, we’re a bit further along with Graham’s GT rebuild-I’ve just introduced some cheap but cheerful, Jagwire brake cables. While Graham locates the wheels and I await derailleur cables, I’ve sanded some superficial glazing from the Alivio pads and I’m leaving those stainless steel inner wires to stretch to capacity. Then I’ll re-tension, prune and superglue the ends to stop fraying before it starts.
Premium grade cable sets, such as those Jagwire Elite presently stopping the Univega and are immune to such vices-simply tension, tighten the anchor bolts and trim to size. Budget models, though generally faithful servants benefit from a different approach.
Having set cable tension, pump brake levers ten times in succession to induce some slack. Loosen those anchor bolts, pull the inner wire through again and snug tight. I lean toward leaving them overnight and re-tensioning the next morning. They will have stretched to capacity by this point, so once tweaked, shouldn’t induce any short-soiling moments when tackling a 1in4 descent. Same basic principle applies to derailleurs.
Right, well that’s it for this entry. Off for a chat with someone about a gravel bike...
