Re: Are touring bikes old fashioned?

How long before Shimano electrify and Di2 all their mid to high end transmission parts? The traditional touring bike may eventually become harder to spec with a suitable mechanical groupset that can be repaired at the side of the road..

"Low rider" front panniers are designed to get the weight as close as practical to the steering axis,,,,in fact even if the weight is centered on the front wheel axle, then the weight is still in front of the steering axis, by the amount of the fork offset. Any load in a barbag or front panniers makes the steering feel different, and when the load is in front of the steering axis (it usually is) then the load has a sort of "pendulum" effect on the steering, so that once the steering gets moving then the momentum of the load will tend to keep it turning.

I have to say that the sort of maths associated with wheel flop makes my head spin.
Turning the steering makes the front of the bike (frame?) drop.
Does a front (low) pannier also drop? I try to think about it, and my head spins.

I wonder if a load centered on the steering axis has as much effect on the steering feel as a load centered on the front axle?

If the front load exerts its effect on the steering due to wheel flop, then you would get the same effect with the same load carried on the frame eg. where the top tube joins the head tube?

I need to lie down now!
Maybe it's easier if we just look where we going ( or want to go when steering around corners ! ) :)

Personally, I’d think the nomad would be ideal for that trip. Sounds a great trip and one where you want the journey to be the focus not the bike. Lots of good suggestions above as well and you’ll not go wrong with most of these.
Another vote for Thorn from me.
Their frame designer Andy Blance regularly spent time during the UK winter product testing in South America.

Have a think about Tony Oliver.
Everybody else says steep head angle/long fork offset = short trail = twitchy.
He says shallow head angle/ short offset = twitchy
.....now, do you think both of these statements can be right?

I'd suggest both could be true in theory, but would stem length and weight distribution could also contribute?

Re: An overview of steering geometry, part 1 (a long read)

Can much more be said and discussed in Part 2 I wonder? I must admit to being baffled why the Mountain Bike Industry seem to keep making bikes with even shallower head angles.. I'm also sure the only reason why these mtb's are also getting steeper seat tube angles is to help aid the function and prolong the lifespan of the dropper posts.

Re: New European Sleeper Timetable.

CJ wrote: 22 Dec 2021, 3:14pm So: is Cycling UK using any of the half-million windfall from their closure of CTC Cycling Holidays, to pay a first-rate campaigner to get the level of to- and trans-european cycle carriage needed for trains to support international cycle-touring as aeroplanes do now? And why, given the way Cycle magazine has been flight-shaming us with articles pretending it's oh-so-easy to take your bike by train instead, have we seen NOTHING in those pages about these new services?

Because it's not just European Sleeper. After a bit of Googling I discovered that no sooner had Die Bahn axed City-Night-Line, than OBB launched cycle carrying NightJet trains to and through Austria. Admittedly only a paltry six bikes per train (so no use for group travel) and completely useless if you're coming from UK, because the only Nightjet service that comes even part of the way to Little Blighty (to Köln) does NOT carry any. More interesting is the news that from 2024, Midnight Trains plans to connect via Paris, destinations as far apart as Porto, Madrid, Rome, Berlin, Copenhagen and yes - even Edinburgh! There's no little blob on their routemap for London however. Perhaps they're reckoning that by 2024 the 'Auld Alliance' will see Scotland back inside the EU, in which case they'll skip the Untidy Kingdom's inconvenient border and customs hangups by locking the doors and not stopping here!

Anyway: is Cycling UK talking seriously to these companies, or Eurostar at least? I doubt it.
Some interesting and valid questions raised here by CJ. Sadly I feel that Cycling UK is being run by the equivalent of the UK government !

Re: Show us photos of your inappropriate touring bike

Interesting how we get a few posts on here with examples of small wheeled bikes - clearly they are as appropriate as any bicycle for touring !

It's no my favorite part of the mag, I do read them, though mainly to pick out the things they've got wrong.

I noticed with the Thorn Nomad MK3 review on the main text the fork was referred to as the Thorn bike packing fork rather than the twin crown disc fork which was actually fitted... The small geometry drawing which accompanied the article also quoted the rear OLN dimension as 142mm - clearly incorrect for the Rohloff hub (135mm OLN).

They won't, the Troll is one of those recently discontinued.
Surly Bridge Club is the closest with either 27.5" chunky MTB tyres or 700c tyres.

Re: Along For The Ride with David O Doherty

I've watched all three programs and finding the series slightly disapointing.. kind of hoped it would be cyclings equivalent to Paul Whitehouse & Bob Mortimer's Gone Fishing ( I've no real interest in fishing , but find the series good entertainment.) Maybe David O'Doherty and Channel 4 can improve things for a second series..

Re: Vintage Peugeot (?) value?

I had a very similar model ( Equipe) back around 1987..£95 from Halfords..a friend of mine had a Peugeot Gold model again, same frame but with similar level of kit and paid £130 from a catalogue. As schoolboys back in the day, we thought these Peugeot's were better and nicer than other bikes available at this entry level price point. Was quiet happy with mine once I'd upgraded to alloy wheels.

One looked at my bike and said 'what sort of bike is it, is it a Bickerton?'
If you keep it, you will have to get used to sundry gents telling you a whole load of stuff about Moultons - and yours in particular. Some may be factually accurate, most will be drivel.
A guy at a cafe recently asked me "But how fast can you go on those little wheels?"...

Re: Are there better solutions? (Moulton)

...and the Moulton Space frame can be split making for easier transportation / storage ! Slightly OT I know, but a valid reason ( compomise? ) for not riding larger wheels/tyres.
