Re: What type and length of rivets?

Or do as I did when the rivets pulled through my front SKS guard and use a rear brake bridge on the front. Actually made the guard much more stable.

Re: Dynamos - Hub or Bottle?

Re: Cycling shorts - any recommendations?

Current favourites are Lusso Carbon bibshorts, made in Manchester too! Comfortable for over 300k. Endura FS260 Pro a close second.

Re: Failed B & M Lumotec IQ2 Luxos U

Mine died in similar circumstances after four years, it had worked flawlessly until then. Fortunately I had a 5 year warranty as I bought it through Rose Bikes. They refunded no quibble and I've ordered a B&M IQ-X instead, and will use power banks to charge/top up devices. I didn't take mine ap...

Re: Tyre Pressure for Small Wheel Tyres

volume is a complete red herring; doesn't change anything much. cheers Why is that? Genuinely interested. Surely a smaller volume tyre will need a higher pressure to support the same weight than a larger one? (all other things being equal). Is it that the variation in bike tyre volume isn't big eno...

Re: Tyre Pressure for Small Wheel Tyres

I was contemplating this just the other day. Running 32mm Panaracer Minits on my Moulton. With an all up weight of about 90kg (say 40 front 50 rear) according to Frank Berto’s tire pressure chart I should be running 50psi front and 65psi rear. I tried these pressures briefly but they felt in danger ...

Re: Brompton equivalent

These have had a protracted gestation but now seem to be shipping: https://www.helix.ca/ Quality and innovation, but at about £1700 I don't think Brompton will be losing much sleep. According to https://www.bikeforums.net/folding-bikes/1051531-helix-update-80.html - they've shipped five bikes, are ...

Re: Moulton SST -- reasons (not) to buy?

To bring this thread back from off, off topic to just off topic this is an interesting article ( https://journals.sagepub.com/doi/abs/10.1243/09576509A01305 if you can find a paper copy or have deep pockets. Much of this is focused on the fully enclosed Moulton for speed records. But, according to T...

Re: Moulton SST -- reasons (not) to buy?

Big wheels go faster than small wheels. Nowt to do with rolling resistance or tyres or tyre pressure ................ though they do affect stuff in the real world on a bicycle. Agreed, and I think back in the day Alex Moulton only got close to rolling resistance of larger wheels becasue of his spe...

Re: Moulton SST -- reasons (not) to buy?

All other things being equal larger diameter wheels/tyres have less rolling resistance than small ones. So in MickF's mecanno experiment above the large wheels would be faster provided the slope was long enough to overcome the lower inertia advantage of the smaller wheels (and for the inertia advant...

Re: Moulton SST -- reasons (not) to buy?

I don't have a great deal to add to the comments posted already but FWIW I've been riding a second hand (but very little used) TSR 30 for the past 12 months. This replaced a traditional Reynolds 653 tubed, 700cc wheeled, Aravis Audax. Moulton is Campag Centaur/Chorus 10 speed triple, Aravis was Shim...

Re: Moulton TSR rear tyre wear.

Interesting discussion. I've got Panaracer Minits Light PT on my TSR, but they've only done about 600 miles. I'll update as and when they wear.
