Re: Shiny bikes & their advocates

I find my hours still always have 60 minutes in them whatever I'm riding. :wink: Bicycle Rolling Resistance gives a 5-6W difference, is that really enough to make minutes difference to an otherwise identical setup? both the speed and the load will be different from the test conditions so the actual...

Re: Sachs and Sturmey Archer Compatibility

If you have some basic tools and a load of bicycle parts it is easy enough to rivet this sort of chain using a short length of old galvanised 14G spoke as a rivet. Just drill the holes out to 2mm, insert the 'rivet' and peen the ends over with a little light hammering. It doesn't matter much if the ...

Re: Cleaning a bike

apologies if this is b-obvious but you of course don't point the jet directly at the seals. You do clean everything though. For example if you point the jet at the back of a ST crankset there is a pretty good flow around the BB axle which removes road salt and mud quite effectively, but not so viole...

Re: Cleaning a bike

seals only work if there is a film of lubricant in there. When that film is gone then rainwater, road dirt, road salt etc easily penetrate the bearings. When that film is present you can -with due care- wash your bike. If pressure washing automatically destroyed bikes, all my bikes would have died, ...

Re: Sachs and Sturmey Archer Compatibility

your new toggle chain is not designed to couple via a screw thread; it is intended to be used with spring loaded anchorage. https://www.sjscycles.co.uk/hub-spares/brompton-gear-cable-anchorage-sram/ it wouldn't be very difficult to rivet or weld the new chain to the old adjuster, so maybe you could ...

Re: brinelling

How do you explain that when Brandt switched to cartridge bearing headsets, he had no more headset pitting problems? he originally had a long and ridiculously flexible 1" steerer. His change to a cartridge bearing headset may well have coincided with the change to a much stiffer 1-1/8" st...

Re: Sturmey to Shimano sprocket splines compatibility

FWIW individual shimano sprockets are normally a fairly rattly fit onto a freehub body too.

Re: SRAM new 'AXS' for MTB/road

the thing is that the trickle down of technology means that you can often buy a bike that is 9/10s as well made as a top of the range model was ten or fifteen years ago, but at a much more competitive price. Eventually certain types of technology are consigned to the bargain basement and may be manu...

Re: Cleaning a bike

if you have good seals, good grease, and are careful where you point it, jetwashing is fine. I have routinely jetwashed my bikes (some of them hundreds of times) with no ill effect. I have equally well seen bikes ruined. BTW if your seals and lube are not up to much then it doesn't matter if you jet...

Re: Shimano Freehub replacement dilemma

so how many hubshell interface (spline style) types are there please? lots but yours is the most common and I think lots of freehub bodies will fit and work. this page https://www.cykelpartner.dk/kassettehus-shimano-deore-xt-8-gear-fh-hf08_Y3A598070.html has a photo from the reverse direction and s...

Re: Shimano Freehub replacement dilemma

there are dozens of shimano freehub bodies that look about the same. The good news is that a lot of them can be made to do the same job too, provided the interface to the hubshell is the same. Design variations include; a) hubshell interface (spline style) b) washer at hubshell interface c) bolt dia...

Re: 'Mighty' branded freehub

the land rover grease is about as good as you can get if you want to buy some that is readily available.

BTW it is best to be proactive with maintenance. If you wait until there is an obvious problem, the thing will probably get damaged before it gets maintained.

Re: 'Mighty' branded freehub

there are lots of off-brand freehubs out there. Most of them are used in OEM hubs that are supplied with a variety of brands of bike, so if you buy a trek, Bontrager, felt, specialized, giant, cube etc branded freehub you are really getting a KT, joytech, quando type freehub. Most of them are OK. So...
