Restraining Orders











Ive continued to reorganise and ahem, rationalise the garage before sanctions were imposed. Most things have been simply relocated to easily accessible and clearly labeled storage boxes. However, an out-of-control heap of perished and part worn tyres, were consigned to the tip. Clear outs can be cathartic and I feel better for this reasoned and yet ruthless culling. I also found a few tubes, which had succumbed to the puncture fairy but still perfectly salvageable. Yes, there were a couple of fully loaded patch kits.

Two for the fixed, two for my Univega. The latter’s sealant fed Kenda thorn resistant tuber had also self-healed, having been fed a bit more air and rotated a few times. The science behind self-sealing tubes is pretty straightforward. The sealant remains dormant until the tube’s punctured, whereupon it’s forced the affected area, by escaping air and rotational forces.  

Holes up to 3mm diameter are pretty much their limit and you will be left with a very sticky mess, should a blowout strike. Famous last words, the Tannus Tyre Armour seems to be holding out and performing rather well. That said; our 32mm section was a little on the precise-side. This meant I had to switch to a slightly narrower, 700x28-32, rather than a 32-35. Technique is another consideration, when mounting and its crucial to avoid pinching.  

The easiest way, is to have one tyre bead aboard the rim (as you would, when fitting a tube). Install the Tannus Armour within the tyre, seat the tube, slightly inflated, into the armour and then mount the tye. Given the increased girth, this bit’s a little trickier but nothing a decent lever, such as my Cyclo Workshop model, or this more portable Crank Brothers   Speedier Tyre Lever won’t iron out.   

Sometimes some chemical assistance will help ease a stubborn bead home. I’ve found a quick, localised blast of Muc-Off Silicon Shine https://www.sevendaycyclist.com/muc-off-silicone-shine-polish, or indeed, Juice Lubes Frame Juice Frame Polish very effective. Washing up liquid can also prove a useful, inexpensive lubricant, although  minimise exposure with plated, polished and painted surfaces.  

Staying with Workshop, I’ve been enjoying these Facom multi-tools.  

A bit big for bike mounted luggage perhaps and a little too short for some stubborn workshop applications. Nonetheless they’ve tackled most jobs pretty easily-including recessed brake/brifter mounts. The Univega’s Microshift Centos is on the right-hand side, hidden by the lever hood.  

More convenient that the fixed’s Cane Creek V brake levers, which are deeply recessed. Access requires a very willowy 5mm key and negotiating the inner brake wire https://www.sevendaycyclist.com/cane-creek-v-brake-drop-bar-levers . That said; there’s sufficient oomph for shifting arthritic quill stem and seat post binder bolts. The Torx version is particularly useful for vulnerable, or slightly chewed fastenerss- cleat bolts being cases in point.  


After a few hundred miles, I’ve performed another saddle swap. The Selle San Marco remains pride of place on my fixed gear winter/trainer. I was surprised to discover the covering is in fact, calf hide, not a micro matrix. I don’t object to genuine hides per se. However, I would’ve preferred cowhide, since the animal would’ve had a longer and (hopefully) happy life.  

I have in fact switched the Pro Stealth for the Pro Turnix, which had until very recently, had graced my fixed gear winter/trainer. Music to my derriere. Not that the Stealth was a poor choice, rather just that fraction too firm, for me.  Harmony restored!  

The weight penalty is proportionately quite steep but in real terms, only 71g and still a bit lighter than the Concor. I’d subverted a wet crotch, courtesy of the Carradice SQR luggage on my fixed but my Univega’s full-length guards make this a non-issue.   

Save fort strong winds, this corner of the southeast has been largely unaffected by Storm Ciara, which is something of a relief. Many communities have experienced serious flooding and disruption. Nonetheless, I’ve been particularly alert to potentially weak branches and similar hazards when navigating tree-lined lanes. Nonetheless, heavy rains mean there’s plenty of standing water.

Some folks want the convenience of clip-on guards. Steve rates this Zefal Swan Road Rear Mudguard https://www.sevendaycyclist.com/zefal-swan-road-rear-mudguard  He also popped over to Bicycles By Design to play with some e-bikes https://www.sevendaycyclist.com/ebike-day-with-bicycles-by-design

Worth The Squeeze










200 miles in, I’m pleased to confirm that upgrading my Univega to the Centos 10speed setup, has been a resounding success. Even this horse was intrigued by my setup. With the Sun Race SP570 mech extender, the Centos copes effortlessly with the 11-28 setup, without feeling over-stretched. Ratios between 36.8 and 93.6 seem to cater for most occasions, and weary legs.
Plenty of torque when accelerating away from the lights, yet tall enough to avoid spin out down 1in7s at 35mph. Some initial cable stretch combined with a quick shot of lube, seems to have corrected minor indexing reticence. Most obviously clambering to the 28-tooth sprocket, and mid-way through the cassette.
Though far from spongy, pulling the front brake’s inner wire through a few millimetres, restored familiar “stop on a sixpence” bite. This is helped in no small part, by the lever’s travel, which is much greater than the shallow reach 9spd predecessors.
Last but no means least, I dialled the left pedals’ tension screw a little tighter, since there had been episodic, unwelcome release. The cleats were only recently replaced, and in good health. However, patterns are by nature accurate by degrees.  
During this bedding-in phase, I stuck with the FSA chain’s factory lube, rather than opting for the otherwise excellent Squirt Long Lasting Dry Chain Lube https://www.sevendaycyclist.com/squirt-long-lasting-dry-chain-lube . These lubricants are widely revered for their relative cleanliness and staying prowess (I’ve had 400 miles from a helping, during a dry summer).
Serendipitous too, since these Zefal Extra Dry Premium Chain Wax and Zefal Pro Dry lubes arrived from Bob Elliot &Co. Seems the first batch were coveted by a courier. Thankfully, the second arrived without incident.
I seem to be gravitating towards wax-based lubricants these days, so have taken that route, first. Will be interesting to see how it compares to the Smoove https://www.sevendaycyclist.com/squirt-long-lasting-dry-chain-lube , Weldtite TF2 Advanced Ceramic Chain Wax https://www.sevendaycyclist.com/tf2-1 , or Weldtite TF2 Ultra dry chain wax https://www.sevendaycyclist.com/weldtite-tf2-ultra-dry-chain-wax
Cool mornings are a theme of late, so I’ve reverted to long sleeve base layers and jerseys. This Prendas Ciclismo Bordeaux-Paris Long Sleeve Jersey is proving perfect for temperatures between 9 and 14 degrees.
At the upper end of this scale, a bit of zipper dropping comes in handy but that’s what I’d expect, from long sleeve garments. Balmy weather, we’re promised, is just around the corner. So, in anticipation, here’s my review of its short sleeve sibling https://www.sevendaycyclist.com/prendas-ciclismo     
Elsewhere, Emma Hillyard has been putting the Primal EVO2.0 Women’s Short Sleeved Jersey through its paces. https://www.sevendaycyclist.com/primal-evo-2-0-jersey  
The Velo Orange Accessory Mount has been growing on me too. We had a few teething problems. The combination of “bolted” construction and relatively generous payloads have demanded re-tightening. Thread lock appears to have cured this. The resin camera mount also proved annoyingly prone to misalignment.
This was traced to the ball joint top. Switching to the mighty Minoura V100 has sorted that. Vice like grip, perfect for bridal path blasting and unaffected by persistent, low level vibration.  Not that I’ve noticed much of that, thanks to the Acros Wrap Silicone Handlebar Tape and Primal Onyx gloves… https://www.sevendaycyclist.com/primal-onyx-gloves
