Have a look for KCNC jockey wheels as they make a 13t .. But as Kimmo said alloy jockey wheels do then to be noisier then plastic

I would hazard a guess Ed is talking about .. an unladen weight below 3,050kg are allowed to drive as fast as an ordinary car above 3,050kg the speed limits are restricted as vans / light goods vehicles ?

That picture of the Slim Chance was taken at NAHBS 2019 according to google.

Ti hammer proposition, it's not the head mass.

That's exactly why titanium head hammers have a place. Try swinging a heavy mass all day long. As you are a man of science you'll understand the impact on the nail is govern by two factors .. mass and velocity^2 .. Kinetic energy. So speed the velocity up and the mass can decrease = less fatigue.

Titanium hammers are widely used in carpentry and on construction sites for framing. Think about titanium being about 45% lighter and you'll understand that although they're a lot more expensive they're less fatiguing then wielding a hammer with a steel head if you're on the job all day every day. The theory behind them is that because it's lighter you can swing faster and more energy is transferred to the nail for less effort. They're usually also paired with shock absorbing materials for the handle eg traditional wood to further reduce fatigue. The only justifiable reason for the Silca hammer is travel weight on planes .. or you could buy Abbey Tools and forgo the 3D printing.

The refrigerant in that car right now is probably the R134a that’s been in common use for over 20 years. Car manufacturers started switching to R1234yf circa 2016. R134a's effect on the ozone layer is insignificant and it’s non-toxic. But it is very bad for the greenhouse effect. It’s approx. 1300 times worse than CO2 when you calculate the GWP against standard protocols. R1234yf is flammable and highly toxic particularly during combustion when it releases carbonyl fluoride - that's similar to one of the chemical weapons used in the first world war - but it has a very low GWP of about 4.

If I remember correctly. You have to place the full piece and the spring into the bottom of the post. Working from each side at a time you then fit the 2 half pieces by compressing the spring with the piece being fitted until the raised knob on the bottom of the piece and locate in the full piece. Then repeat. Once you get it back together the saddle then "clicks" into place as the rails slide down the ramps and push the half pieces against the spring.

Traditionally an ICE car average cost was 0.72 tonnes of Co2 for each £1,000 of retail price during manufacturing. So a moderate £40,000 car would generate roughly 22t Co2 just to get it onto the forecourt.

Let's talk about the pitfalls of these clean air strategies .. consider the scrapage scheme and the fields full of serviceable cars traded for new ones. The plug in grant encouraging new electric car sales - and don't forget with that one how the ceiling has dropped and now the retail of some cars previously eligible has dropped with it (thinking of you VW) to maintain their eligibility and encourage new electric car sales ...

I'm just saying I agree with cleaner air, it's everyone's right, but let's look at the complete picture and not just a strategy that suits today's headline

The Slim Chance is from 1991 with the full period correct Mavic groupset.

I had (sold some time ago) a 120mm ITM Krystal to which I fitted a PMP Ti draw bolt. The stem weighed 184g on my scale. The Krystal I found pretty flexible. I preferred the 3t Pro Chrome, although I never weighed that.

A quick google suggests Ti cycles offer a Ti draw bolt in M8. Other stems worth looking for although they may not appeal are WR Compositi and Syntace

Sounds like a helicoil has been used to repair the clamp and whomever did it has done it incorrectly. There should be no movement, almost preload since the helicoil is pretty much a spring that you are putting into a smaller hole than it is at in it's free state. It should not fall out !

That's an ultra torque crankset.

Athena 11s was ultra torque until 2011 when it was changed to power torque.

Sweet wings cranks .. The original eeWings cranks

Sorry to correct but the shims fit inbetween the lever body and handlebar to move levers further away for larger hands ..

Limited run A1 Quattro is the only alternative in that size until the Yaris becomes readily available second hand. But Audi's aren't lairy, other then in a straight line. Audi's bias is always towards handling stability.

Fiesta ST and forgo the AWD. If you need more speed the Mountune.

That's an £78 eBay J&L cage on a 7800 mech. Not a Ceramic Speed OPSW.

I'm liking the Fizik Cyrano Snake at the moment .. Not quite traditional shape though

That's a wizard rods conversion on the Beetle. Was styled on the Willys Coupe that were the iconic hot rod at the time of the conversions release.

That looks very much like an Argon 18 Krypton Pro

Brass, like other alloys, comes in a range of versions with each version exhibiting a different set of properties. Navel brass, as the name implies, has a very high seawater resistance due to the higher copper content .. more expensive. I'd guess Serotta spec'd it being risk adverse, given Serotta's US customer base, to actions for seized adjusters.

Glws .. Sure these won't be here long.

Mi16 engine was a popular period engine swap for the 205gti.

It can't be wireless as per SRAM derailleurs because of SRAM patents. So Shimano will have to use a different approach .. the semi wireless one ?
