"Battery Saving Compound", that's a new one to me!Got these tyres cheap today I think£ 40 ish . Not sure about the battery saving bit though what you reckon
.Got two headsets for price of one as one got lost for a while in the post.

Being Merkin I guess you'll understand the "big bum" half.
Me too . Hope their better than the Swalbe Ebike John Watt tyres I bought last year."Battery Saving Compound", that's a new one to me!
3 foot 5mm usually gets the youn engineers scratchingtheir heads. But who invented 10ths of a foot ?.
It is a consequence of being raised in an Imperial culture in an Imperial country, but with an education system determined to make us all metric (thank the EU for that!). We have EITHER a split personality on the subject OR a stunning versatility.
There is story that illustrates this well. A guy goes into a woodyard and asks for some 2" x 1" (universally called two by one). The shop guy says we no longer sell 2x1, it's all metric now, will 50 x 25 do? (millimeters).
Yes, says our hero, I'll have two metres please. (See how swiftly he gets with the program!).
The shop guy says is that 6' or 8'!

I would say one of those is appropriate, my wife would however would choose the third option which is "crazy as a box of frogs". Can't disagree with that tbh
Further to the metric vs Imperial. Bikes are as bad.
We have bar diameters in mm, but are actually inches, just stated in mm. Tyre widths are in inches, wheel sizes in inches, but rims are in mm. Seat posts are in mm. The chain is half inch pitch (calling it 12.7mm although accurate is by the by). If the original designer had been French, he/she would not have chosen a fractional size like that, he/she would have gone for the nearest whole mm. There must be more examples.

I have the metric system, or more accurately the SI system (Systeme Internationale) to thank for my career success.
When I was at school, I was taught in the imperial system and I never really understood physics and mechanics. We had the same terms for weight and mass and some seriously weird units for lots of other terms (slug-foot anyone?) Consequently, I never understood whether I was supposed to multiply or divide by 32 (feet per second per second) to get the right answer.
I didn't do too well in the exams and I thought I was a bit thick. When I went to Technical College to study engineering, all the teaching was in SI. The Si system has a coherent set of units (better than the metric system) and is very easy to understand; no problems of knowing whether to multiply or divide by the acceleration due to gravity. All of a sudden everything made sense! I got 95% - 99% in all my exams for two years and got the Henry Brown Prize for meritorious work, with only one given each year. From thinking I was a bit thick to that prize turned me around. I went on to get an honours degree in Mechanical Engineering and lots of well-paid jobs and early retirement at 57. And all because of moving away from the Imperial system. But I still prefer to drink beer in pints, it is a human scale quantity.

You lost me quickly there Steve so I must be thicker than you .I have the metric system, or more accurately the SI system (Systeme Internationale) to thank for my career success.

You just have a different super power!

I thought everybody knew, a standard doorway is two metres two inches tall?I hate metric, I measured up in mm for a new back door for our house and cocked it up, it came 2" too big
I only wish that was the case, my home is a very old stone cottage built in the 1800's where the only things that are straight are what we've fitted in it, spirit levels weren't invented when our house was built, or the builders (and I use that term very loosely) couldn't afford one
I think they must have used the transparent hose pipe method with half frozen water or wonky string lines don't get me wrong we love it as its quirky but is also challenging when we tackle any home improvements, lets just say its interesting, and we're glad its not listed

Torque ON & Dirt Jumper had last week new (Magura) brake day. Today it was time for the Spectral ON CFR LTD. Set of Magura MT7 Raceline. Combined with Shimano XTR M9120 levers and Magura MDR-P rotors.
Now all bikes have the Magura Raceline setup
Still some work to do... .Mount motor covers, bed-in brake pads etc...

I guess that I've been lucky over the years that I've never needed one out on the trail ..but bought a spare mech hanger to go in my back pack ..
Tempting fate?

2" too tall or 2" too wide?I hate metric, I measured up in mm for a new back door for our house and cocked it up, it came 2" too big
One is a fixable problem; the other is a disaster!
Consider it as a talisman. As long as you carry it, you will never need it.I guess that I've been lucky over the years that I've never needed one out on the trail ..but bought a spare mech hanger to go in my back pack ..

The downside is that the longer you carry it around with you the stronger the wish that you had saved your money, the stronger the urge gets to sell it, give it away or leave it behind. As soon as you do that, you will need it, 20 miles from home in a sleeting rainstorm.
I can take care of that for you! Go on let me, let me. Think of how much it will go up in value; there is always some tosser from the big city who has a dream to live in a listed building...........................we love it as its quirky but is also challenging when we tackle any home improvements, lets just say its interesting, and we're glad its not listed
Think I bust one at Glentress in about 20 years ordinary bike riding. Two broken on Levo in the past year along with dérailleurs.I guess that I've been lucky over the years that I've never needed one out on the trail ..but bought a spare mech hanger to go in my back pack ..

Finally bit the bullet and bought Somme Crankbrothers DH Mallet pedals - only two runs over the weekend and slowly getting used to them!
Tubby G
❤️🔥 Hot Stuff ❤️🔥
When the circus arrives
But do they come with the free red nose , face paint & braces ?
You should already have those???
2” too tall, I had to cut a 1” rebate out of the stone lintel and the same off the stone step, it caused all sorts of other unforeseen issues like me having to knock off all the old plaster from inside the head of the doorway too so that the top of the new door didn’t foul when opening and closing, fortunately for me the old plaster was VERY thick so I was able to dot ‘n’ dab a piece of plasterboarding on and skim it with some multi finish plaster2" too tall or 2" too wide?
One is a fixable problem; the other is a disaster!
That’s a case of wishful thinking pal
