Re: Coloured Mudguards

the rear mudguard looks like it was fitted under considerable strain; over time the mudguard will deform or crack if it is fitted under strain. Maybe that was it?

Re: Newbie with a Vintage mtb

it still doesn't look very much like a Ti frame to me; several of the tubes are very heavily manipulated (eg the chainstays), the way the seatstays are made is unlike ti frames that I have seen, the way the cable stops are done is again unlike other Ti frames, the way the seatstays join onto the rea...

Re: Newbie with a Vintage mtb

interesting bike, that. Rear brake looks like an Odyssey Pitbull MkI rollercam brake. IIRC such brakes were flavour of the month in ~1987 to ~1989. I don't recognise the fork but it looks like one from about that time too. Frame looks more like TIG welded steel to me; I can't be sure from the pics b...

Re the elephant bike. This is still available new (at some fantastic cost, I think about three times what an elephant bike costs) from pashley as the pashley pronto. It is basically a robust design, however do remember that the elephant bike is basically a used bike with a freshly painted frame; I w...

yes. If you use the wrong lube in some things you will shorten the service life considerably.

Re: Should I convert to a Rohloff hub - costs vs benefits ?

it is a commercial grade oil that is made in industrial quantities, and doesn't cost that much when bought in (proper) bulk.

Re: 20" aluminium mudguards

probably you didn't have the axle in the back of the dropouts before either; that can make a good mudguard fit virtually impossible.

Re: Thread size on Sturmey Archer Toggle?

IIRC it is a 'fairly special' thread, not easily found. If you buy a spare control rod (which you will probably need anyway at some point) you will get a another one.

BTW your mudguard fitment is made considerably worse whenever you decide to slide the wheel into the back of the dropouts.

Re: HPV grasshopper rear wheel offset ?

on a lot of trikes the rear wheel is less dished than 'it should be' which is actually a not too bad compromise; the wheel sees high lateral loads and the adverse effects of excessive wheel dish are worse than normal. Anytime the wheel is not in the centre the loading is uneven and the machine wants...

Re: Long tail cargo (possibly e-bike), or regular bike for commuting with 1 child in hilly town

local to me Bakfiets are popular https://www.urkai.com/wp-content/uploads/2016/03/Bakfiets-NL-black-canopy.jpg to the extent that there is a Bakfiets parking problem every afternoon outside some schools. However these machines might be easy to handle (much easier than a longbike with a load on, less...

Re: 20" aluminium mudguards

re silence; I really don't like riding with a rack on my most-used bike. The transmission on that bike is virtually silent (IGH with nice chain and no tensioner of course) which means that I can very often hear the rack; it resonates with normal vibrations from the road, and I can hear the wind swoo...

Re: Cassette options (if any) for 6-speed system

I used to crush the spacers in UG cassettes just by pedalling hard in top gear. Basically the top sprocket would (for me) never stop moving entirely; it'd move, I'd think it was tight (and it was) but then the plastic spacers would slowly creep under the applied load, and (often months later) the to...

re belt drive on Rohloff: For the last few years Rohloff have been fitting their new style driver which makes life easier for the average user; it allows easy replacement of the chain drive sprocket which is now fitted with a spline. This replaces a unique (multi-start) screw thread arrangement for ...
