Subtle Changes, Great Results











Little n’ often is the way when it comes to winter maintenance. Many problems can be swerved, simply by keeping bikes clean and lightly lubricated. Brush tyres down to remove sharps before they can burrow into the casing and cause flats, remove grit from brake pads, wipe the chain’s side plates, especially if you’re running a wet lube. Mudguards (fenders) and big flaps, such as these RAW https://www.sevendaycyclist.com/raw-prismatic  also offer considerable protection to bike and rider alike.

The Zefal Extreme Wet (Ceramic) is proving reassuringly stoical-filmy given 325miles or so but on a derailleur set up, the chain reclaims the excess coting the cassette. I noted the indexing had gone slightly off. Cable tension tweak-sorted.

Funny how things can be textbook perfect on the workstand, yet prove out, on the road/trail. Zoned in, I also turned my attention to the brakes since regularly tackling waterlogged roads sees brakes and other mechanisms coated in dodgy, grimy stuff. This can gum things up, causing the brake arm to drag/stick. The front Genetic CX Cantilevers https://www.sevendaycyclist.com/genetic-cx-cantilever-brakes are great stoppers but needed a quick bit of TLC. Balance screws tweaked, I gave the screws, springs and inner cable a quick shot of heavy-duty maintenance spray, which has brought stopping back up to scratch.

Braking sorted; the Schwalbe Kojak grip the wet, mushy leaf carpeted lanes like the proverbial leach. I have finally retired the rear Continental Contact Speed Reflex https://www.sevendaycyclist.com/continental-contact-speed-reflex-ty  due to a succession of small but rather deep, sharp induced gashes. Thankfully, Monday morning’s puncture proved a slow affair that struck less than 5 minutes from base.

I was aware of a faint hiss but put it down to the swoosh as we glided through the puddles. Any loss of pressure was undetectable until several hours later, when I noticed the rear was sitting pancake flat on the lino floor protector. Aside from being quick rolling and grippy, there’s no tread to catch glass, thorns and flints.

However, slicks with very supple casings are more vulnerable to cuts. Brush them down regularly-Oxford tyre scrub https://www.sevendaycyclist.com/oxford-products-tyre-scrub  is probably the best I’ve used to date (not surprising, given it’s tyre specific. Some If slicks aren’t your thing, Schwalbe Marathon Racer might light the spark… https://www.sevendaycyclist.com/schwalbe-marathon-racer-tyres

Elsewhere, Bob Elliot & Co www.bob-elliot.co.uk have sent the these FLR Defender Winter Shoes (mtb booties in my book) to test. Timely, in many respects, since my much-loved Lake finally came to the end of their life (sole) after ten winters. Talking of which, no winter cycling discussion would be complete without an overview of lighting  https://www.sevendaycyclist.com/blank-ypcqd 

Road versions would be a more obvious choice in some respects, but I only use twin bolt pedals these days. Besides, I want a sporting chance of staying upright when temperatures dip and winter takes hold. Not so easy to hobble back and forth to your bike with an exposed Look/pattern cleat.

I’ve switched the long serving and very likeable Passport Cycles Bike Packing Seat Pack Medium https://www.sevendaycyclist.com/passport-cycles-bikepacking-seat-pa  for this Zefal Z Adventure R5. As the name hints, it’s a 5 litre model (compared with the Passport’s 7) and  a simple, single compartment design, which may prove less convenient. However, it promises to be waterproof, rather than water-resistant and the simple mounting system is intuitive. Incredibly secure with zero sway-despite the single strap and on narrower post diameters.  

Elsewhere, despite the present UK “Lockdown” Town centres seem to bristle with pedestrian traffic and a surprising number of “non-essential” shops/businesses remain open. Not unexpected, given the UK government’s consistent mishandling of the pandemic, U-turning and subsequent loss of public trust. However, in stark contrast to the initial lockdown, where road traffic fell to 1950s levels.

Who Loves Ya Baby?











 My Univega’s front Continental Speed Reflex tyre succumbed to a slow flat, inducing some squirm and prompted a switch to the Schwalbe Kojak. It also provided an ideal opportunity to check pads for any imbedded contaminant etc. To my surprise, the comparable 26x2.0 Kojak are considerably lighter than the Continental (527g against 675g) which may be attributable to several factors.

While both tyres are wire beads and similarly matched in terms of puncture resistance (at least by their respective ratings) the Continental’s sidewalls https://www.sevendaycyclist.com/continental-contact-speed-reflex-ty  seem a little beefier. They are supposedly designed to entertain tyre driven bottle dynamos, which may account for this differential. Not that I’ve felt any inclination to try, since I’m a hub dynamo devotee and wouldn’t revert by choice.

The Kojak seem to roll a bit faster (not that the Continental could ever be considered remotely sluggish) but the Kojak can also be run at 70psi, the Speed Reflex a more modest 58psi).  

Whether these features will have implications for durability and puncture resistance remain to be seen, especially as we transition from mild, breezy conditions to wintry stuff. However, I’ve also switched to some heavier duty Schwalbe tubes. Tubes are one of those components easily overlooked. The generic bundle types, though worthy enough tend to be a little on the thin side, which has implications for puncture resistance, patching and indeed, pressure retention.

Having reached my conclusions regarding the Tru Tension Banana Slip Wet Lube https://www.sevendaycyclist.com/tru-tension-tungsten-wet-lube , I’ve switched to the Zefal Extreme Wet Ceramic. Apparently, its’ a ceramic reinforced, Teflon-based formula reckoned to cling on, rain, shine, snow, and ice. The latter has been threatened on these shores. Some crisp 5am starts and glazed surfaces have been a slight culture shock, but confirmed that both tyres grip asphalt like the proverbial leach

Personally, I’m of the opinion these adverse weather predictions are designed to grab headlines and online traffic. Forecasting has also reached the point where it’s so accurate in the immediate sense, its ironically inaccurate longer term. Either way, I’ll be sticking with the Pro-Viz Reflect 360 Gloves https://www.sevendaycyclist.com/proviz-reflect-360-cycling-gloves  which seem to have most bases covered.  

I digress, back to the lube. A little certainly goes a long way. Literally apply a tiny drop of the white elixir on every, freshly cleaned link, give the cranks a few rotations (wiping any excess from the side plates) and you’re ready to go.  

So, what are ceramics, then…In this instance it refers to a microscopic layer designed to infiltrate and bond with the surface, theoretically protecting it from the elements and premature wear. Thus far, it’s certainly slick and less gloopy than many wet blends but I suspect good housekeeping (weekly wiping of side plates, jockey wheels and cages) will be mandatory.

With falling temperatures, layering is even more important. Primal Europe have graciously sent me these funky Comic Book arm warmers and Showers Pass, their Elements Jacket. Apparently designed with mountain bikers in mind but versatile enough for other disciplines and indeed, off the bike.

It’s a seam-taped 2.5 layer waterproof/breathable laminate with front pockets, core ventilation points, a removable hood and features a carbon print lining, which theoretically subverts clamminess and odours, which can be an issue with some 2.5 layer models, which I’ve otherwise been endeared to. Lighting is always a big draw, but particularly as the days are much shorter. I’m still very endeared to the Magicshine See Mee units discussed last week but this Lezyne Stick Drive is another neat design.

30 lumens isn’t jaw dropping by contemporary standards but the optical technology mean its very bright and useable, even in the lower settings. I’ve deliberated whether the 4lumen mode could be culled, although in common with some other Lezyne I’ve used in the past, it could be a life-saver, giving you something to limp home on, should reserves tumble.

Moonlit Miles & Running Repairs FGG


Polaris Bikewear www.polaris-bikewear.co.uk have just sent some samples of their challenge range, which are designed with input from Tegan Phillips and other epic adventure tourists. While retaining the classic cycling cut and materials, other features have been tweaked for comfort and practicality.

Starting with the Nexus short, this is a six panel design made from a subtle navy blue Calvico (Polyester/Elastane) weave. One of the most unusual, though very subtle features are an elasticated mesh pocket on the left leg and a zippered “valuables compartment” on the butt compartment. The former have swallowed my jailor’s bunch without feeling intrusive, overburdened, or indeed ejecting mortar fashion at the first bump.

Inserts are probably one of the most personal contact points-they’ve gone for a medium density TMF, a blend of Coolmax fibres to keep the crotch region arid while a silver anti-bacterial component safeguards against infection. 50 miles in and things are favourable, which isn’t always the case- another 450 or so will give a much better idea of their capabilities and compatibility.


Tasteful Orange/Blue/Yellow silicone leg grippers are more generous than most and designed to prevent gathering and that unsightly branding when its time to strip off and hit the campsite shower blocks. …They also compliment the Challenge merino ride socks. Strictly speaking these are a Merino mix with padded heel and toe sections. Longer cut gives a more civilian look, while giving ankles and lower calves a sporting chance through long grass and brambles. 

Then we have their Traverse Jersey, another Merino based garment for fast wicking odour management. Not sure lime green is my colour (but there are alternatives?). This deviates from the traditional jersey script in several respects. A polo type collar gives better protection from harsh sunlight, while also offering a more civilian look when off the bike. Longer sleeves and front zipper offer similar benefits. The latter has one of the most user friendly tags I’ve ever come across-effortless climate control and subtle reflective detailing brings it to life around dusk and beyond. 


Given the more casual design brief, Polaris has been very inventive with the pockets. Two generous diagonal “Power mesh” stretch pockets sit on the sides and will manage larger mini pumps, smart phone, wallet etc with no hint of ejection over poorly surfaced roads/trails-to date at least. The men’s version features a similarly deep, zippered nelson pocket on the right breast. I’ve hauled my faithful compact camera around without feeling obviously overburdened.

It’s been unseasonably warm this past week or two (well into the late 20s/early 30s) for me to put their windproof pioneer jacket through its paces, even to arrive at any formative opinion.

It’s a two layer polyester design with a vented rear panel  that follows the more relaxed narrative, so won’t draw unwelcome attention and could also be worn as a general outdoor jacket-looks good with Jeans. Looking forward to seeing how it copes with wet and windy weather, the stuff synonymous with autumn and falling leaves.  

Elsewhere, the Univega’s Vittora Randonneur trail tyres finally succumbed to irreparable cuts in the casing. Several thousands of miles under their belt, I had previously patched a gash in the rear tread twice with a “boot” and filling the remainder with high strength glue but a third signalled their retirement.

I’ve gone back to those Vittoria city runner, a nigh on slick 26x1.6 road/commuter model, which rolls a lot faster than their 28tpi casings would suggest. Now, things go in fashions- most of us took the slick route with our mountain bikes during the mid to late 90s.

These days there are abundance of competitively priced, capable road biased flat bar commu-do-mosts, some with derailleurs, others hub transmission that are arguably much better working bikes, mtbs with slick tyres, full length guards, rack and a taller spread of gears remain very versatile four seasons’ bikes. Having succumbed to a some minor knee discomfort, I’m staying off the fixers for now and taking advantage of the Univega’s lower, variable gears and masses of pedal float 

Talking of derailleurs, tickly, noisy changes from its rear Microshift mech were attributed to a dog-eared rear outer cable. Given the inner was in rude health, I simply pruned some leftover compressionless Jagwire housing used on the Ilpompino’s front disc. Crisp shifting restored in two minutes flat-little victories!
