Ben Hur













 Life is continuously changing, evolving and thus we must adapt, accordingly. Bike Journalism/Kit testing aside, I am a fettler. My two-wheeled fleet is, to some extent always evolving. Not for change’s sake, or to fill a void in my life, rather ‘cos stuff wears out, or in some instances, breaks.
On other occasions, I ruminate on something, explore a few options, THEN decide on the solution(s). This avoids consumption of resources. Money, time, energy/labour and of course, storage.
To some extent, bikes are like relationships, as we mature and (hopefully) gain greater self-awareness, we understand what works for us. I am deeply attached to the Holdsworth and Teenage Dream. However, for general, everyday riding, something with ‘cross type geometry, clearances and indeed, big tyres, is my preference.
Life and people are here to teach us lessons, it is up to us, whether we heed, and learn from them. There are a wealth of people/personalities I navigate on a professional and personal basis. I am pleasantly indifferent to most, deeply attached to a few. There are people with enormous amounts to offer, but nothing good/right for me.
Another narrative, which has endured from my teens, is user-serviceability. Anything I own must be relatively straightforward to maintain properly, and to the highest standards. This also goes for cars, and motorcycles. Back then, the ability to braze/frame build was high on the list.
However, opportunity/finances never presented, and I’ve long recognised it’s a skill best outsourced to those with years of experience. I like welding. A semi-commercial MIG welder capable of taking commercial Argon/CO2 cylinders would be a sensible investment for light fabrication, repair etc.
Fully equipped workshops with TIG welders. Oxyacetylene, Jigs etc are not. A week’s frame building course, does not a master craftsperson, make “Building by numbers” is one thing, being able to problem solve and deliver impeccable results is something entirely different.
To paraphrase my late Grandfather (40 years welding experience, 6year apprentice trained) “Any fool can blast metal together. Making something stick, and moreover behave according to draft, is something entirely different.”  
I do share his somewhat surly and difficult charm, although would like to think I’m more moderate, dare I say agreeable, overall. Contexts established, I leave frame building/modification/repair to the likes of Lee Cooper, and Maldon Shot Blasting & Powder Coating. https://www.sevendaycyclist.com/gravel-bike-on-a-budget 
So, with all this in mind. I was overtaken by one of THOSE urges. Pandora’s box sprung open and with it, the yearning for Titanium…Forks. Yes, for Ursula…Not that there’s anything particularly wrong with the existing “school chair” setup, with its beefy legs.
That said; they were aimed at the “Jump” market, so there’s a weight penalty, relative to the original triple butted uncrown, or something like Kona’s iconic Project II. A Chinese manufacturer got in touch, offering me a set with disc, cantilever and mudguard eyelets. £450 was an absolute deal-breaker. If something comes along, at the right price and specification, I’ll take a closer look.  
Elsewhere, I’ve resurrected my Revolution Cargo Trailer (Bob Yak homage) from hibernation. Its primarily been used, not for shopping/utilitarian purposes, but rather assessing the laden handling prowess of test bikes. It needed a good polish, which proved the perfect opportunity to test this Muc-Off Cherry Pop Silicone shine (I also took this opportunity to treat the Univega).
Silicones certainly add shine-especially to plastics. They also add lubricant to polymers/rubberised components, which is good for suspension components. However, unless used sparingly, silicones can also prove dirt traps. To assess this, I delivered ours directly to the trailer chassis, tourer via micro-fibre cloth.
For the time being, said trailer can follow behind my beloved tubby tourer, hauling various weights, to scrutinise gearing more critically-now the honeymoon period’s done. I have a few minor niggles with the Yak homage.
Firstly, the finish isn’t particularly good. Its not poor, rather softer than I’d expect. Once it gets tatty, I’ll get it blasted and powder coated. Similarly, though the wheel is identified as being 16x1.75, offer a branded slick/road version against it, and, nope.
Since its functional enough, I’ve decided to whip out the valve core and introduce some latex type, puncture sealing splooge. Aside from the obvious, I needed to use it up, and this seemed the obvious candidate.
Letting the bike do the lugging, is a golden rule of touring and longer commutes. https://www.sevendaycyclist.com/tug-jobs However, depending on your payload, for shorter hauls, rider mounted luggage can be a boon, especially filtering through tighter gaps in traffic. Well-made messenger bags are old boots tough, (usually) weatherproof and ooze cool. Little surprise they’re so popular.
Statistically, many car journeys are less than 2.5 miles. Between this and 5 miles or so, messenger bags have a ln their favour. My Chrome Industries (model) is still serving me well, and Steve’s been putting this Chrome Modal Vale Sling Bag through its paces  https://www.sevendaycyclist.com/chrome  .
He’s been similarly impressed with this Carradice Kelbrook Satchel, which is made here, in the UK  https://www.sevendaycyclist.com/carradice-kelbrook-satchel

It Just Burst!


No, not that kind of Latex calamity. I’m talking tubes and flats (again). Not a year passes without someone, marketing a new cure for the common puncture. Well, quick fix resurrection is probably more accurate. Timely these GUP sealant and inflator cannisters arrived at my door.
 

These work to the “spare wheel in a can narrative”. Find and remove any offending sharps from the tyre casing(s). Open the valve, deflating completely. Shake the cannister vigorously, plug the yellow “smart” head on and then push upwards to release the mixture of sealant and CO2. In common with pocket Co2 inflator tools, delivery is very controllable. Releasing your grip, eases the flow.
Other designs I’ve used previously haver managed around the 60-65psi mark. This sort of pressure’s enough to limp home on but not going to blow a 700x25c into smithereens. Jettisoning the whole lot in one press isn’t problematic.  
I’ve managed 90psi inside these 38mm Soma Shikoro https://www.sevendaycyclist.com/s , which is impressive. Whip the head off, then spin the wheel quickly, so sealant can race to and plug holes. Give the tyres another, quick onceover; then scoot off.
Sounds perfect for the Monday commute, or when you’re weary, toward the end of a long ride…
Alas, there are limits to any goo-based product. Should they fail, the result can be a big ‘old, undignified mess!
Most will seal small holes (1mm or so) with no problems, provided the sealant is still mobile (varies from brand to brand but expect a year or so’s useful service from this genre).
Much bigger, or something close to the valve, spells new tube and big clean up. So, ensure you’ve a decent spare holidaying in your luggage, and carry some wipes/cloths too-just in case. The Shikoro succumbed to a very aggressive sharp. This had sliced deep into the centre strip.
Taking an educated gamble, with the GUP reaped great reward. It didn’t, with this Panaracer T serv.  A phantom flat by all accounts and not one that, I can attribute to my malevolent farm cat, either. (Although, I’m convinced the old boy takes exception, to the scent of some tyre compounds). Further inspection revealed a weakness around the valve stem, one seemingly common to the budget bundle types.
600 miles in, I’ve reached my short-term conclusions about, which have delighted me with their quick, yet super compliant ride quality. Soma Fabrications Supple Vitesse EX tyres https://www.sevendaycyclist.com/soma-fabrications-vitesse those seeking something more tourist; should look at these Schwalbe Evolution Marathon Supreme https://www.sevendaycyclist.com/schwalbe-marathon-supreme-tyre
Steve gave them a good blast through Cumbria https://www.sevendaycyclist.com/cycling-in-cumbria-s-border-country . He reckons they lack the outright invulnerability of the Marathon plus but are that bit friskier, easier
Trailers and folders also deserve good rubber.
However, all too often, when it comes to trailers, OEM types are the cheapest knobblies going. Functional enough, to a point. However, something I’d look to upgrade expediently.
Now I use my Yak homage as part of the testing process. This might be a tourer or adventure bike’s stability, or “just” seeing how tyres perform in different contexts. Dave Taylor at Schwalbe UK has learned of this, so is generously some Marathon Plus.
Elsewhere, having discovered the Mango body is in fact, GRP, I’ve been approaching motorcycle refinishers, to see if they’d be interested. I’ve had a couple of very positive leads. Another, similarly helpful spray shop said he didn’t have the room but…had some contacts in Northamptonshire, who would be able to facilitate.
 
A couple have been very enthused about the project and given, back-of-an-envelope quotes. That’s for John to decide but progress, nonetheless. Nothing from Sun Star either, so he’s machining a spider from a budget Sun race triple…
I on the other hand am beset with excruciating toothache, which as suspected, is an abscess. Prescribed antibiotics and more, heavy duty ibuprofen painkiller, I’m presently sporting a pout. The kind, some people pay a fortune for. Wasn’t expecting these side effects though…
