Re: Tandem Crossover Chain 3/32 vs 1/8 ?

Oops I meant 10mm! On the eccentric, that's 20mm on the overall chain length. When it's at the forward limit, turning to the slackest doesn't allow sufficient slack to remove a whole link. :(

Re: Tandem Crossover Chain 3/32 vs 1/8 ?

My Dawes Discovery tandem doesn't allow sufficient adjustment in the eccentric to avoid the use of a 1/2 link in the chain. The eccentric allows approx 20mm adjustment. 5mm more and I could have removed a whole link. :wink:

Re: Tandem Crossover Chain 3/16 vs 1/8 ?

I use 34 tooth chainrings bought from SJSC https://www.sjscycles.co.uk/chainrings/compact-chainring-steel-110mm-bcd-5-arm-silver-34t/ Cheap as chips. :D As Brucey says, bigger rings feel stiffer. I have tried both 1/8 and 3/32 chains on the original 38 tooth rings I had. I was disappointed with the ...

Re: Saddle moving

Yes that sums it up nicely. I wish I was as good with words as you clearly are. I prefer numbers. :D

Re: Saddle moving

Mrs rjb has a single bolt hockey style seat pin on the tandem. This has no serrations and occasionally tilts rearwards. No amount of tightening seems to cure it. I roughened the surfaces with some emery which has sorted it at the moment but if it reoccurs I may resort to filing some serrated teeth o...

How does that compare to the sods of peat dug by our closest neighbour for approx 10% of their electric generation. :shock:

Re: Biopace chainring

I've seen some using 1/2 a clothes peg, the wedge shape is made for this purpose. :lol: Drill a hole through and tie it around your bars with sufficient length to reach your brake lever. BTW I use a 1" length of inner tube for my trike to hold the brake lever on. :wink:

Re: Replacing a fence

As an alternative has anyone any experience of post and rail fences made from recycled vehicle tyres?. They should last a lifetime as they will never rot.

BS6102.2 came in in 1992 so part 1 introduced in 1981 narrows the date :wink:

Re: Topgear MTN stem - anyone got any details?

My MTB of that era had a 21.15mm diameter stem fitted, bmx standard. A common 22.2mm (1inch) stem dosent fit. Something to be aware of before you buy one. Measure first, buy once. :wink: It was one of these btw. I got around it by opening up the fork column with an industrial 7/8" drill (22.2mm...

Re: Rear vertical drop out thicker on the drive side

All though having it on the drives means that the rim will be offset with less dishing which is not a bad idea. :?

Re: Rear vertical drop out thicker on the drive side

It looks like a spacer but its odd thats its on the right side as this throws an extra 5mm requirement on the rear mech shifting. I cant tell from your photo but is their a gear hanger there as well? If its to accommodate a different oln then i would have thought it should have been on the left side...
