Re: HP boats

Pedal power is interesting, but there is a huge gap between the needs of racers, where hydrofoil canoes are probably the way to go, and the pedal power of touring boats (which interests me). Gear ratios , prop angles etc, and not least how you get the drive from pedals to prop.

Re: Two separate threads?

I think the idea of to separate threads is great -just not separating the discussion into two partisan echo chambers. Instead, I propose: one thread, for the discussion of the efficacy and desirability of helmets, as per the present discussion, and another for those wishing to wear helmets and who w...

Re: Gears: are 3x setups extinct?

Us recumbent pilots have a similar need for a wide spread of ratios. I find Sugino, Sunrace, still make decent triples, and you can always buy a set of bare cranks, and suitable bolts and spacers to build up your own using rings from TA or others. (Although this is a route I have not personally trie...

Re: Linear Frame number or Serial Number

Agreed, it’s a very special’character’ in the bike world. I once said to Peter Stull that the Linear is not so much a bike as a system for building bikes. I like to think my remark inspired his later redesign of the short wheelbase version -but I doubt it! There was a SWB by the way, but it was shor...

Re: Trying to find a suitable bike at 27st?

I’m not sure I would worry so much. Bikes can carry staggering amounts of weight in the form of cargo. Huge amounts of the supplies for Ho Chi Min’s victorious army in Vietnam was transported by bike after all. (Although often pushing rather than riding!). A reasonable quality second hand MTB, or so...

Re: Bestest ever bicycle brakes... ?

a very common problem with V brakes is that the cable run to the brake fouls on something or is strained in one direction; if so this messes with the brake centring in an apparently unpredictable fashion. Yup, had that one too! :roll: And while I’m being splenetic, what about that time when naughty...

Bath Bristol Speeder

To the roadie on the Bath-Bristol path this afternoon travelling at speed in the vicinity of Saltford, shouting at other cyclists to 'Keep Left! Keep Left!' . . . . . . I really hope you had nothing to do with the child I encountered shortly after, in the direction from which you had come, limping, ...

Re: Bestest ever bicycle brakes... ?

When I first discovered v-brakes I thought they were great -so logical and simple! Then I discovered how hard it is to get and keep the b*****rs centred. First there's adjusting the fiddly screws that, like derrailleur limit screws, are an obscure bicycle engineer's joke, being specially designed to...

Re: Are drivers aggressive really?

I come down firmly on the ‘yes’ side in answer to the thread title question. Not because of any sweeping generalisations about the characters of motorists, but for an even more depressing reason. It’s called ‘systemic violence’. The whole motor/road system is based on an assumption that is at root, ...

Weell, while all the issues you mention do exist, I have to say it sounds like you have been extraordinarily unlucky in your experiences of disc brakes!

Re: Bestest ever bicycle brakes... ?

Thanks Brucey, your reply is helpful. I note the calipers I recently fitted, designed specifically for road touring (they say), have uprated piston seals. Boiling of hydraulic fluid would appear to be a concern with long mountain descents, not that I do many of those, but I did fit the Shimano ‘Ice ...

Re: Bestest ever bicycle brakes... ?

I am interested by two of Brucey’s points and would like to know more: 1. Under what conditions do disc brakes fail completely and without warning? (I really want to know this!) 2. Conventional wisdom among mountain bikers and others has always seemed to be that discs are more consistent in the wet ...

Re: Crank lengths !

This discussion comes up a lot in recumbent circles where many of us use short cranks to avoid excessive knee bending. This is because on a ‘bent one can put alarming forces through the knee by bracing against the seat back. At an acute angle the leg muscles do not have good mechanical advantage and...
