Re: starting again aged 70ish

Welcome!
Depending on where you live, I'd consider riding well away from traffic if possible - that will get your confidence back. If your bike hasn't been used for a long while, check your tyres are still rideable in particular. My local CUK group caters for all ages, types of riding & abilities - I'm sure you'll get a warm welcome!

Just solder the connections....its a longer lasting job than crimping, which obviously stresses the wire as you crimp.....solder splints the wire by joining the strands together.
For insulation, use heat shrink sleeving https://www.ebay.co.uk/itm/303927706138 ... d51faba4ea...loads of suppliers.
This also re-inforces the "join" ....its the join which is weak with a crimp, they fatigue where the conductor isn't properly supported between the cut end of the insulation and the crimp.
If you think bicycles are a demanding application, try motorbikes.

Brake/gear wires......I use silver solder to make a proper finished end.
You may wish to read this then:

I would add a caveat regarding crimping: it has to be done correctly. I used to do production testing where I'd gently tug wires on their crimp connectors. I also had to re-solder 100s of joints due to dry, missing or too much being used. The problem with many crimp tools is getting enough leverage.
I have no experience of motorbikes but I totally agree that cycles can be demanding enough. I can remember as a kid having to bash my Ever-ready front light regularly because the contacts had become corroded or lost their springiness.

Enjoy it while your still able -- my 3 month injury lay off has made me appreciate cycling, the freedom and health benefits it brings much more.
Agreed - though I'm not sure if "Golden Ages" in anything is a useful way of looking at stuff. I was hit in my left thigh during a commute that took a while for the massive bruise to go - my bike damage & clothing was paid for by a mortified young driver. Such happenings do prompt a re-evaluation.

My observation is that the minor roads around where I live in mid-Berks are probably far more dangerous that the straighter & wider major ones & that the level of motorised traffic has now exceeded pre-pandemic levels. Both bikes now sport bar-end mirrors but the jury's out on just how useful my new Garmin radar is in practice. At least I can do light off-road since converting my hybrid.

Re: Today I realised my true mountain bike rides are over

I've been using double-sided SPD pedals since the huge fat original ones. I set both my current pairs to near minimum tension. I've never had an issue with accidently disengaging - expect when I've fallen off.
Most times I've had an accident, my confidence also took a tumble for a bit. Choosing a route to suit one's mood or weather seems like a plan.

A 20 - 200Nm 1/2" torque wrench bought off Amazon. Unfortunately, like most tools & even things like shoes laces - are made in China.

Nope. Been using SPDs since the original ones - their float suits me fine.

I don't know for sure but yes some of the loss of capacity will be because some of the power is being wasted as heat during discharge. Old batteries ( or cells) have a higher internal resistance than pristine cells. When the internal resistance gets too high as the cell ages, when you attempt to draw power from the cell, the high internal resistance of the cell means that power is wasted at heat in the cell instead of being delivering as power into the load.
The recharging cycle on Li ion batteries is fairly complex & IIRC, starts off with a CV phase then CC then trickle. If the internal resistance increases with age, I'd suggest the charging time will take longer. A quick google seems to verify this.

It was pretty sensible of Apple to do what they did but was pretty stupid not telling people or allowing the user to choose with a setting.

Re: Cleaning a new chain

Stradageek wrote: 22 Sep 2021, 8:29am I feel that a bicycle chain, or just a chain manufacturer somewhere should know the answer. I was an electronic component reliability engineer and we had to know how long our chips would last!
We live in a world where the "truth" is at best, malleable. "Opinions masquerading as facts" springs to mind. The "truth" seems to get set when enough people believe something to be the case. I'm sure many of us can remember TV toothpaste adverts where an extremely long toothbrush head had a good inch of paste squeezed onto it. This was a subtle way of distorting reality to increase sales. I would tend to believe KMC over P&G! Politics is an example of the difficulty of differentiating fact from fiction - who's truth?.

I don't personally clean a new chain but just wait for signs of it needing lubrication (increased noise or rust!). I do sometimes remove a chain & clean it in petrol, wash thoroughly, dry, re-lube then refit with a new Missing Link if required. Some thoroughly clean a chain then dip it in hot lubricating wax, presumably shaking then wiping off the excess. I do use a chain bath so as to not remove the chain most of the time. I've also left chain replacement too long so had to also replace the cassette. If the whole drive chain is worn, I just run it into the ground then replace the lot - fine for a commuting bike journey running parallel with train stations!

We now have the choice of applying either wet of dry lube. I do know that when I used some "dry", the weather turned wet & it washed out with signs of rust within a couple of days & the "wet" version lasted a couple of hundred miles. I do have a sneaking suspicion that using both can be filed under the heading of "marginal gains" over one designed for all conditions!

Re: Cleaning a new chain

I watched, heard & read so many differing & often contradictory ideas regarding chain cleaning. KMC recommend not cleaning a new chain before fitting according to a recent GCN vid because their lubricant has thoroughly penetrated the rollers. Quite when you stop relying on the original - who knows. Another video from god knows where suggests using petrol compared with an ultrasonic bath. I'm sure others could find info that refutes either!
I did use some dry lube back in winter to find it washed out during heavy rain within a couple of days & can remember the makers of WD40 suggesting their spray was perfect as a bike chain lube despite having too low viscosity for the job.

Absolutely! My 1st 2 MTBs were rigid but did have a lower top tubes, 26x2" knobblies but crap cantilever brakes, my Ridgeback does have very decent MTB hydraulic disc brakes with 160mm rotors & enough clearance to take 40c tyres. I wouldn't want to run anything much wider than my 35c ones without innertubes on rims with a 20mm internal width. This gravel conversion suits the available offroad where I live & my advanced years! It also means I only have to juggle wheels rather than a 3rd bike.

Seems so. Hermes finally go around to delivering the cassette for my new rear wheel. Both rotors slotted into their callipers just fine. Did some minor adjustments then went for a ride this evening. 1st offroad in nearly 20yrs. Hell of a blast.

As an aside, I can't figure out why so-called gravel bikes have drop bars - their handling is stifled by them! Mountain bikes have wide bars for a reason.

Re: QR Gravel wheels - tubeless.

I was out exploring a few weeks ago on my Giant Defy when I ended up running out of tarmac & ended up crossing gravel on treadless 25c tyres. I stayed upright with some effort. This was my 1st offroad in about 17yrs.

I enjoyed it so much, partly due no near-misses with motor vehicles that I looked into buying a MTB again to discover the choice is laughable at the moment. I decided to buy a new pair of wheels instead, obviating the need for a 3rd bike. These have skewers to fit my hybrid with adaptors to fit the Defy's thru-axles if required - this flexibility was one reason why I went with Hunt that will take axles up 15mm dia.

Much to my surprise, the Schwalbe 35c X-ONE ALLROUND's went on with some effort by hand. The rotors fitted fine but the supplied rings splines are non-standard so fitted the Shimano ones instead. The new cassette arrives next week but the lock-ring won't fit to the free-hub body so will be contacting Hunt Monday.

If any of you go with Hunt, I doubt if you will have the same issue with their free-hub & you'll have considerable axle flexibility if you want to swap between bikes.

Cyclist who waits for others to greet him first complains about fellow cyclists doing the same. :)
I sense some clarification is needed: approaching cyclists, I nod or say something if the circumstances allow - I don't wait for them to do so first. The number of cyclists passing who acknowledge me has dropped to almost none. This never used to be the case - it's almost as if it's uncool. My point is that when so few bother, I've become far more selective.

Re: Greetings whilst riding

Due to increased age, I occasionally get overtaken by other cyclists :wink: I would say only a tiny percentage of those cyclists acknowledge my presence. If they do, I always reciprocate. I'm far more selective these days who I greet due to being met by silence for my effort from most. I've been returned with abuse a couple of times, once when I greeted a guy on a racing bike when on my hybrid - must have dented his ego, he also turned off soon after! Older folk are more likely to greet but people's sex makes little difference. I usually nod to oncoming cyclists.
