how slow do they get?
two weeks ago i spotted that the rear wheel of my work bike had a visit. hey ho - the first for many a long year. decided to use up a new tube and fix the old one later.
swapped it out, pumped it up and hey presto, back on the road.
the problem with the old tube was less easy to find so inflated it to about 35psi and left it hanging in the shed. two weeks later it has lost pressure but not so much! have never had anything nearly as slow as that....is this a record?

Re: Re-using an old 8-speed Campagnolo wheel
slightly alarming to read that campagnolo 8 speed stuff is regarded as 'ancient.'
i won't tell my summer bike (due out soon hopefully.)

Marchisio i think.Brucey wrote: ↑18 Mar 2024, 10:43am IIRC Miche do sprockets (into the 30's IIRC) to fit campag freehub bodies. Not that it isn't especially difficult or challenging to make your own, but they also do various width spacers, so you can build up miche cassettes to be compatible with almost any modern indexing system.
IIRC ambrosio(?) used to do a replacement cassette where each sprocket used a slightly larger splined fit and the cassette came with spacers and carriers to suit. I mention this because IIRC this system was quite popular BITD,(so there is lots of campag 8s stuff out there), the system supported larger sprockets (which don't tend to wear out) and you could use as many ( or as few) of the special sprockets as you want. Given how useless (for touring) the smallest sprocket in a standard cassette is together with how easy it is to add a sprocket at the other end of the cassette it wasn't exactly surprising to see how many people ran basically standard cassettes but without the smallest sprocket and with an added larger one.
Anyone with a welding set and half an ounce of brain power pretty much has the World at their feet here, I reckon. Whilst it isn't even slightly tricky to weld HG type steel sprockets together so they are strong enough it is tricky to get everything to stay concentric and sufficiently free of distortion. However, if you can manage this, there is nothing to stop you from rebuilding any worn campag fit cassette using shimano sprockets, any size.

Re: "Plus" vs breaker for fairy protection
one thing that i have noticed in the past few years are increasing amounts of screws, drill bits, powered screwdriver fittings, nails etc simply dropped into road side gutters. if walking i often pick up several within a mile. i'm sure that there weren't nearly that many in the past. disposable tools? careless people?

Re: "Plus" vs breaker for fairy protection
that's quite a while for it to be lodged..!UpWrong wrote: ↑11 Mar 2024, 12:15pmYes, the screw put a hole in the rim tape and with the tyre deflated I can believe that iit would quickly have damaged the rim if I hadn't stopped immediately. I wonder if the screw had been there for a few hundred years, sealing the hole it created and only becoming apparent as the tyre gradually lost pressure with subsequent rotations.
As you say, rather different from the usual piece of flint, glass or a thorn.

Re: Fill that hole
very much so. i have reported several potholes in recent weeks and they have been attended to. the problem being that it is usually in the order of "wellying in half a bucket of tarmac" and the hole re-appears sometimes in days especially when there is so much rain.MikeF wrote: ↑3 Mar 2024, 7:40pm Filling potholes is "sticking plaster". It should not be needed in the majority of cases - the road should be resurfaced so that potholes do not occur. In most cases noting the section of road that's failed should be what is reported, and not pinpointing the exact position of potholes. There are several reasons why potholes occur. Many are caused by utilities just back filling a trench and resurfacing the backfill, leaving the road with a mixture of surfacing and base that wears at different rates.

Re: Belts and chains
does your current bike have decent mudguards with a lengthy front mudflap?
do you clean the chain regularly?

Re: SKS Rennkompressor rod washer replacement, how?
i have both a rennkompressor pump (a red one with a leather retaining strap for the handle) and a silca. the latter has a simple, push on chuck and is far easier to use than the SKS - the head of that is far too big and tends to flop out of line with the valve causing sealing issues. the pumping action itself is fine though.

Re: Are there any modern cranksets that aren't goppingly awful?
in pure engineering terms, to take the forces involved, what would be the best shape? something that doesn't taper at all?
does the orientation a square taper 'hole' make any difference? (it did BITD when i broke a chainset side crank as the stoker of a tandem to find the replacement....er.....was differently oriented to the left hand side. bah! )

Re: SRAM axle size?
not yet no. it's on the way to mrs mig in another part of the country so i won't see it for a month or so. then i'm hoping to fettle it into a wheel - should the thing work ! note to self - find a rim to take a 35c tyre in the next few weeks.
i'm hoping that the axle is fairly standard despite the hub being an uncommon one - but you never know!

SRAM axle size?
I have been promised an SRAM I-light front hub to play with for use as a spare next winter. Good stuff.
However it has no fixing nuts on the axle ends. Can't find them size/info anywhere online.
Anyone ever used one?
Thanks
