Beacons of Hope?





The leaves are rustling, daylight is fading, and the UK is facing the prospect of blackouts during the darkest, coldest days of winter... Well, my blood will certainly boil, and don’t anyone dare throw a romanticised “It’ll be just like the 70s” line my way. Madison www.madison.co.uk sent us these rear lights to test. We’ve the Infini Metis, the Infini Tron, and The Kryptonite Incite XBR Rear Brake Light.  


What’s interesting about these then...Well, they’re all at the same price point (£34.99) and the Metis and Kryptonite feature “braking” functions. Interestingly, and more accurately, Kryptonite describes theirs as an “acceleration sensor”. Unlike some others, they cite the sensor will trigger the designated LED when it detects speed dropping by 3.58 mph (5.76 Kmh). Otherwise, it’s a 7-mode model with memory and run times, cited as between 10 and 36 hours.  

The Metis has 5- two steady, three flashing-including a daytime running flash. In terms of output, we’re talking between 10 and 80 lumens. I’m particularly intrigued by the Flashing 2, which is 40 lumens and reckoned to manage 28 hours from a full charge. We shall see... 

 

I like daytime running modes, especially on overcast autumn and winter mornings. The Infini Tron pumps out a maximum of 40 lumens but also has a 50-lumen day flash.  

The latter sounds a little tame by some standards- 100 and 150lumens are increasingly common.  


Indeed, they’re brilliant for soup-like conditions but there’s some debate as to whether these are otherwise anti-social. It does, however, enjoy a large surface area and employs a 42 chip and 10 SMD LED, so will be interesting to see how these lights compare in real-world conditions.  


I’m an advocate of always carrying a contingency light on long rides-even with disciplined charging, lights can suddenly power down, or fail. Risks are minimised by proper charging and other, basic care but just as the best-maintained bikes can succumb to a mechanical, the unexpected can strike.  


An integrated lithium-ion or lithium Polymer cell can only withstand so many charge cycles before losing some endurance. To illustrate my point, the Kranx Strix 100 came to my rescue when an excellent Magicshine unexpectedly powered down, meaning I was still obvious to other road users from a good distance and for the remaining 10 extremely dark miles.  


During this point, I also noted the Souma Leather handlebar tape Souma Leather Handlebar Tape | cycling-not-racing (sevendaycyclist.com) had stretched a little, causing it to turn a little baggy just below the brake lever. To be expected after a few thousand miles and easily sorted in five minutes. Unwrap at the tops, just below the hoods. Tension tightly and uniformly while weaving back up. Some fresh electrical tape sealed the deal. The Souma is certainly weathering and wearing well-not that I’d expect any different from a hide of that quality and price point, but reassuring, nonetheless.   

 

One thing, of course, leads to several others. Next thing I knew, I’d stripped the chain and cassette, given the bike a good wash, since I was there. The Green Oil Dry Chain Wax Green Oil Dry Chain Wax | cycling-not-racing (sevendaycyclist.com) for the theoretically more stoical Momum MIC Wax Lube Momum MIC Wax Lube | cycling-not-racing (sevendaycyclist.com) , then of course, I decided the saddle height was a little too lofty, then a fraction too low. The former causes undue and unnecessary strain on the knees, while also hampering efficiency. (Too high, or too low is inefficient and can lead to knee and other joint mischief).  


Then of course, the seat collar sheared-I should stress I had been using the torque wrench, set to the prescribed 5nms. Thankfully, I had a replacement in the small parts drawer, so switched and took this opportunity to blast some spray grease inside the seat tube and apply a light coating to the Kinekt 2.1 Aluminium Suspension Seatpost KINEKT 2.1 SUSPENSION SEAT POST | cycling-not-racing (sevendaycyclist.com) Shim and height checked, I snugged everything down to 5nm and ticked another series of little jobs off my doing list.


I have ordered a couple of 28.6mm BBB, just to keep in stock should another failure strike here, on the fixed gear winter/trainer (Although I have a nice Salsa lip lock somewhere in the spares bin, so will root for that, should need arise.)

Boiled Bearings & Brake Lights







 I’d been concerned about the Halo Evaura/SP SL9 HALO EVURA & SHUTTER PRECISION SL9 DYNOHUB BUILD (sevendaycyclist.com) hoop- there's been some disc rub and I initially believed this attributable to a slight loss of truth- either the rim or less likely, the Swiss Stop Catalyst Disc Rotor Swiss Stop Catalyst Disc Rotor | cycling-not-racing (sevendaycyclist.com). I’d ruled out the other possibility-broken axle, or skewer. The latter sheared unexpectedly but thankfully, while I was inspecting things from the comfort of home, not ten miles out.  

A trip to Mick Madgett confirmed the SL9’s bearings were cooked. Hub issues had crossed my mind-I’d done approximately 20,000miles and four winters, so not wholly unexpected. Its PD8 cousin HALO CLASSIC RIM & SHUTTER PRECISION DYNOHUB DISC WHEEL BUILD (sevendaycyclist.com) needed overhaul last year, which wasn’t an overly complex, or fraught process. Send it off to Ison Distribution (Their UK importer) pay a small fee and it’ll come back from the factory, serviced and ready to be built into a wheel. 

 

Continuing the lighting theme, I’ve been forming stronger opinions regarding the Kranx Strix 100 and Ravemen TR500 rear lights. The former has surprised, impressed me with its output and presence, across the board. I’d be happiest running it on a best bike-for extended late summer/early autumn evening outings where you need a decent light to get home with. Or as a backing singer to a dynamo/main light during winter. 

 

The TR500 is highly effective and incredibly powerful, though still practical for suburban and town riding in the lower settings. Run times are surprisingly good too, although it does require 5 hrs 45 minutes to fully re/charge. The trick of course, is to charge often 


Not only for convenience but because it ensures lithium-Ion cells reach their suggested service life. It also features a brake sensor, which its TR300 sibling does not. “Brake” sensors or brake functions are useful but probably best explained/thought of, as slowing sensors.

  

For example, a car or motorcycle brake light engages when the lever, or brake pedal is engaged, which in turn, causes other components to physically engage, switching the light on and off. However, those featured on bicycle lights employ a sensor, which calculates/estimates deceleration. Therefore, it’s likely that they will engage more often, which can affect run times 


Designs have improved somewhat in recent years- in terms of sensitivity, so you’re not engaging the “brake” light at the slightest loss of momentum on a climb. I’m still very fond of the Xeccon Mars 60 COB Rear Light TESTED: XECCON MARS 60 COB REAR LIGHT (sevendaycyclist.com), which can run in “brake light” only mode. Again, it’s a little on the sensitive side but the large surface area and slightly translucent casing means it’s a good bet for tagalongs/trailers, or as a sleek single, post-mounted light.  


Those on the Ravemen TR500, and Magicshine SeeMee 150 and 200 are easily disengaged, which is thoughtful. Ravemen CLO6 RAVEMEN CL06 SENSORED REAR LIGHT | cycling-not-racing (sevendaycyclist.com) follows this less prescriptive narrative and employs a sensor that picks up approaching vehicle headlamps, intensifying the output accordingly.  


After a period of drought, the rains have come and its welcome on many levels. Wet, greasy and challenging conditions are perfect for evaluating products. Tyres, brakes, chain lubes or clothing are just a few examples. The Specialized Road Sport are continuing to put a grin on my face, although aren’t quite as sprightly as the CST Czar, or Vittoria Rubino Pro but do seem consistently good-even along waterlogged roads.  


Would be interesting to see how their more expensive Road Elite stablemates compare. Interestingly the latter only feature a centre-breaker strip, not one that runs bead to bead. Traditionally this has meant a lighter, faster tyre but on paper at least, more vulnerable to flats, especially during winter. Winter also means more component chewing filth and caustic grot.  

This coupled with shorter days demands a more efficient approach to cleaning and general maintenance WINTER WONDERLAND ONE | cycling-not-racing (sevendaycyclist.com) Bike washes, though not essential can be very helpful when time is short and grime stubborn. Steve’s been putting this Motorex Bike Clean Motorex Bike Clean | cycling-not-racing (sevendaycyclist.com) through its paces and seems quite impressed
