Re: My Ultrasonic Cleaner

You can put the cleaned chain in a glass container of lube and place this in the ultrasonic bath which needs to contain any fluid, eg water the ultrasonic action transmits through the glass jar and forces the lube into every joint It is safer to use a thin walled pryrex glass as hot spots can and wi...

Re: 101 Uses For An Old Inner Tube...

I have used one as a garden gate closer when the original coil spring bust,and I have one split length ways and fastened onto the front edge of my bench so I can lean the bike on it without scratching, also carry a short section on the tandem to hold the brake lever on when parking up.

Re: rohloff weighty problem?

Of course. I have 30 of them. How many have you got? "Click" to change, then silence as I pedal. Are yours silent as you pedal? Gone are the days when dérailleurs crunched and ground there way up and down the cogs. You may have 30 different front / rear chain positions, but you do not hav...

Re: rohloff weighty problem?

There is an issue changing 8 to 7 and 7 to 8 when 14th will engage for a couple of seconds and this is a problem when climbing hills but only really on a tandem when it is very difficult to back off. It is still an improvement over a conventional gear system and just requires a bit more forward plan...

Re: rohloff weighty problem?

We have a 48/16 setup on our tandem, and when the stoker gets tired on the back we need our 1st gear quite a lot , thinking about going 44/17 next.

Re: IRD FW776 Seven-Speed Freewheel

Shimano do a 140mm cassette hub, try sjsc .Or for more cash try hope or DT Swiss.
You can also get a 135MTB hub and fit the 140 axle from your current hub just adding 2.5mm spacing washers each side.

Re: 32 spoke wheels help please!

Santana team Scandium tandem has 16 spoke wheels so as you can see it's not just a question of number of spokes it's more to do with quality of components and quality of build

Re: WHEELSET RECOMENDATIONS?

Spa make some bullet proof but not necessarily fast wheels I think Chrina rims with 105 hubs would be your best bet probably with a 32 hole front and a 36 rear, Sapim spokes double butted front and non drive side rear plain on drive side.

Re: Threaded or Threadless?

As an aside, if you get a seatpost collar the same size as a threadless steerer tube slide it on next to the headset on an uncut steerer, pile on a stack of spacers fit the stem and cap bolt, torque up the cap bolt, and when correct, tighten the seat collar you can then remove the cap bolt, stem and...

Re: Threaded or Threadless?

I have threadles on my MTB but have just had a Bob jackson made with a threaded steerer because they look so much better, Campag do a record threaded headset, and cinelli and nitto do nice stemsand bars for a period feel to the bike. One advantage of a threaded headset is the ability to alter handle...
