Re: Giant VS Specialized

to use a daft analogy it is a bit like saying "I like eating, and I'm trying to choose between McD's and Burger King".

There's more different types of food than that.

Re: Raleigh equinox

The pic in the original Shimano brochure looks like my hubs....8 speed width but with weird vestigal uniglide threads rather than the flat area needed for an 11 tooth cog. ... That (1991) pic shows a 7s system, (105SC didn't go 8s until 1993, so the RX100 groupset -arguably the tiagra of its day- w...

Re: Campagnolo Record single-pivot brakes – set-up questions

1. At some point they changed from using 5.5mm housing to smaller stuff. If the adjusters are drilled for 5.5mm housing you ought to use ferrules with 5.0mm housing. 2. You can buy the correct campag inserts, so use those. If for some reason you want to use modern brake blocks, space them away from ...

Re: Coloured Mudguards

Are you saying that the rear mudguard has gone out of shape longitude, twisty, canted, as well as radially because of missing it out? . yes, exactly that, although the mudguards was probably also strained before you changed things, just not as much and not for as long. Many plastics do not have an ...

Re: 20" aluminium mudguards

I think the rear mudguard went out of shape because it was fitted whilst strained into a weird shape. A useful axiom for mudguard fitment is that if any one fastening is undone and the mudguard moves appreciably, the mudguard must be being strained out of shape. If the mudguard curvature is correct ...

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...

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...
