Two Deore & Fresh Cable


 







Three rides in and I concluded a slight kink in the rear derailleur housing was causing mischief-it wasn't obvious, until I was cruising on the hoods and happened to take this shot.  I obviously replaced the outer and inner cables upon returning home.  Little surprise that shifting became that bit snappier and free of phantom shifts and similarly unwelcome distractions.

Even if bars look comparable, width and shape can influence things, so if changing contact points, or making wider changes, it's worth changing the cables, ideally during, rather than afterward.  Talking of bars, here’s Steve’s review of the Lomo 3 Litre Handlebar Bike Packing Dry Bag Lomo 3L Handlebar Bikepacking Dry Bag | cycling-not-racing

All part of bedding in, dare I say bonding (deeper) with the build. Not one, but two Deore mechs arrived, which is welcome. The SR Suntour fitted to Ursula is box fresh and the STX adorning Denise’s downtube still has plenty of strength in its spring. Nonetheless, it’s thirty years old and these things tend to expire at the least convenient moment. Both Deore hail from the same era but have little signs of use and plenty of power within their springs. 

I'm sticking with the Shimano CX50 stopper up front since there's plenty of bite and pads are readily available. Temptation was to pop another Kore on, but this is change for change's sake.

Mick Madgett has worked his wheel building sorcery and built the older, non-disc Ultegra dynohub into the Ryde Sputnik rim. Not an urgent job but glad its sorted. I've switched the existing disc braked Nexus Shimano Nexus DH-UR700-3D Dynamo Hub | cycling-not-racing over to Muffin and run the low drag Shutter Precision SL9 HALO EVURA & SHUTTER PRECISION SL9 DYNOHUB BUILD as a second/spare, as need arises. Otherwise, I'm really pleased with the bikes in their present guises.

Denise's 36/26 is actually quite close to the "cut down" trend that struck in the early 1990s, where riders would often forgo the big ring (typically a 48 tooth) in favour of the 38 and 28 since this saved a few grams and was arguably more practical off road. Though there's a lot to be said for triples, especially on a tourer, I've found keeping them on song four seasons round to be something of a chore.

I also ran a Shimano 600 with a Stronglight 48/38/28 setup, and this could also prove temperamental. I should point out this was inherited with the bike, not of my doing and was ultimately replaced with a Suntour XCD six months after the frameset's powder coat makeover in March 1990.  I was a big Suntour fan and remain very fond of the late 80s and early 90s groupsets.      

Elsewhere, I fitted the Blackburn Atom SL computer to Muffin and though accessing the battery compartment is fiddly, thanks to the tiny screws, the rest of the unit, including sensor feel solid in the Blackburn tradition. The display is very clear and the switches similarly solid. Not quite as bombproof flavour of old school, late 80's Cat Eye, but not far behind, so we'll see. 

 

Staying with Cat Eye a minute, I was interested to note they still offer wired versions, including one called the Enduro, which is apparently designed for off road duties. I'd go for a wired model since by definition, they are the most accurate, reliable option, but there's the risk of me embarking on a headset strip/similar, forgetting about the wiring and ultimately knackering it. I've got form for this, having done it before, to a Strada back in 1994.  I spend considerable time connected to the internet in one form or other, to the point where I simply want to decompress and disconnect on my rides- escape, for want of a more involved explanation.  

 

The Lomo Mountain Bike Gloves are still seeing plenty of action and continue to impress in their pleasant, understated way. Also on the test bench is the Lazer Strada Kineticore helmet, a design that blurs genres.

It employs their ScrollSys system for a precise, 360 degree fit, TPU eyewear docking system for parking sunglasses, a rear light mount and Keneticore Propriety Integrated Rotational Impact Protection, offering protection in a similar manner as MIPS. Where the two systems differ is Keneticore Propriety Integrated Rotational Impact Protection is built into the helmet from the beginning, whereas MIPS is added afterward. This ensures it covers the entirety of the helmet and theoretically, improves ventilation, while also using less material.

Hopefully none of us will ever need to call on this, or rely on our lids, but twisting forces can prove particularly harmful in a crash.  

Build quality and attention to detail impresses me at this price point. Simple things like the polycarbonate shell extending around the rim and an intuitive "conveyor belt" type adjuster tightening or relaxing the cradle tension being prime examples.

On the subject of sizing, I went for a small, finding the medium can be a little larger than others. I'm at the upper end of the 51-56cm circumference but still achieved a secure, comfortable fit with scope for caps, buffs and similar headwear. Our sample also coordinates nicely with these Shimano RX600 Shimano SH RX600 Gravel Cycling Shoes | cycling-not-racing and cap
