Been a busy week of tweaking and tuning here, with a welcome procession of test kit, to keep me focused and out of trouble. Summer prevails, despite the harbinger of doom tabloid headlines.
We're prioritising summer based chain preps and related stuff, at Seven Day Cyclist and I'm hoping to get some decent mileage on the Holdsworth before leaves start falling. That said; the nights are drawing in that little bit faster now, which is ideal for testing lights.
The majority of breakdowns are avoidable. Sure, there's always that hole/sharp with your name on it. The best maintained machines CAN let us down, but probability is very small.
I've been alternating between fixed gear winter trainer and tubby tourer this week. Thundering along 1in 4s at 35mph, keeping up with the spiralling revs and putting the Clarks CMD22 through its paces. Paired to The now discontinued Kinesis DC37 fork and Cane Creek V brake lever https://www.sevendaycyclist.com/cane-creek-v-brake-drop-bar-levers, setup was a pig.
I also had to switch to the TRP Spyre's mount, so the caliper didn't bind against the spokes. Quiet, methodical tweaking, diesel strength coffee and minute adjustments won the day. Formative impressions are very positive, although at this stage, I'm not convinced real world performance is superior to the TRP Spyre.
Only time and real world miles, will tell. A sentiment that applies to a wealth of other things. Dry lubes can take many forms, some ceramic blends, such as Weldtite TF2 which cure to a dry, yet surprisingly durable state.
Others are closer to an oil and some, including Muc Off Dry https://www.sevendaycyclist.com/muc-off-dry-chain-lube and Oxford Mint Dry https://www.sevendaycyclist.com/oxford-mint-cycle-dry-lube are closer to emulsions in their consistency. Ceramics tend to require relatively long curing periods. However, the do run cleanest, in my experience.
Wax and emulsions tend to melt in higher temperatures. This may look gunky but dirt and grime are locked within the outer layer. This ensures it doesn't form a transmission munching grinding paste, and given time, the grotty stuff will fall away.
Most noticeably, when its solidified following a cooler period. Unfortunately, in their gooey state, they transfer more readily to hands and clothing. Not ideal, if you're commuting, or doing short "bikes as car" runs in smart trousers.
I carry a couple of latex examination gloves, should a flat/similar roadside mechanical strike. Good practice generally, especially if you are using petrochemical derived formulas.
Speaking of which Rock N' Roll Lubes' UK distributors have kindly sent me samples of the Gold LV and Extreme LV formulas.
LV stands for low vapour, meaning they're non flammable, so can be transported in the post and on aircraft, without special precautions. These are not oils, in the commonly accepted sense, so require a different delivery. Strip the chain and cassette of any pre-existing lube (including the factory stuff).
Shift the chain to the middle of the cassette (as appropriate). Give the Rock n' Roll a quick shake, undo the cap and apply a continuous flow of lubricant into the chain. Once you've built up a decent layering rotate the cranks for five seconds and clean any excess from the chain's side plates, derailleur jockey wheels etc.
Now, leave it curing for a few hours. I'm told the Rock n' Roll family are completely compatible.
Say you wanted to switch from their absolute dry https://www.sevendaycyclist.com/rock-n-roll-absolute-dry-chain-lube to the Extreme LV. There's no need to go through the stripping rigmarole, simply deliver the Extreme on top. The solvents will remove the sibling product and leave the other in its place.
They've also sent us some Miracle Red 3in1 degreaser. They tell me its a bio-degreaser, hand cleaner and stain remover. So, theoretically, you can purge stains from your bike, hands and soiled clothing. In the latter context, it should be applied neat to the affected area, then agitated with a finger nail, then rinsed.
To date, I've used it to purge mildly mucky maulers and dilute as a bike wash, prior to waxing the Univega with this Naked Bikes Pro Bike Wax Special Edition. In common with several other boutique blends I've tested, this one is a hand poured blend of hard and soft waxes.
Apparently, it contains Si02 technology and reckoned to last uyp to 12 months between applications. In my experience boutique waxes, though expensive, relative to polymer based car types, do last a good while.
However, I suspect the maximum periods cited are perhaps, based upon machines in dry storage, rather than daily service. Judging by my Univega, the rich glossy effect is impressive, although, unlike Velo21 Ultimate Paintwork Protection https://www.sevendaycyclist.com/velo-21 , there's no mention of compatibility with matt finishes.
Naked Bikes also sent their Bike Bling and Chain Cleaner. The former is a quick n' convenient detailer, the sort that really brings out the sheen. Ideally, give recipient bikes a sudsy bucket wash first. Unlike the Pro Green MX Aftershine101 https://www.sevendaycyclist.com/pro-green-mx-triple-pack, which is literally blow n' go,
Bike Bling has to be worked in, then buffed to a shine. Hardly a hardship mind.
Every now and then, small miscellaneous parts need running repairs. My tubby tourer's otherwise fabulous Exposure Revo MK1 dynamo wiring was looking a touch weary just above the plug.
Heat shrink was my first idea. I was halfway to ordering some, when I discovered this Thermoworx White morph. Its a versatile polymer along the same lines as Sugru.
Only, it can be re-used. Set too quick? Apply a hairdryer to it, and gently reshape. It reacts with hot water (62 degrees upwards). So, decant some of the beads into an old cup, boil a kettle and pour in.
Stir (an old, clean spoke seems perfect) until it assumes a sticky, toffee like consistency. Mould, apply and leave to set. Setting is VERY rapid, so you need to be prepared to work, apply, and shape quickly. Strictly speaking, its a modification/ "hacking" rather than repair product in the conventional sense.
Aside from the damaged outer dynamo cabling, I've added "scuff bumpers" to my Univega's Microshift Brifters, made replacement end caps for the mudguard stays and sealed freshly spruned cable ends. Pretty confident I'll find several others. Bike related, and otherwise.
