Re: Rim thickness - worn out?

…. Duh.... I suspect that rim manufacturers make their living supplying rims for new bikes and "upgrade" wheels. These people actually want to save a few milligrams, they aren't bothered by longevity, they like the appearance of a shiny machined braking surface next to a painted surface. ...

Re: "Gusset" under downtube

…. Colin, are the excellent steel SPA frames made in the far east ? …….. Steel and titanium, both built in the Far East. At the moment, its the obvious place to go, you can't argue with the price or the quality.....or the reputation, which is important for the end customer. For a long time, some Sh...

Re: Shimano hub cones - common/interchangable?

thanks colin. was once looking at buying one of their cones but had the impression they were quite hard to get hold of in the UK. If (from a quick look) I have it right that table just tells you which wheels manufacturing part you need for each hub? So if you want a shimano part/to raid another ful...

Re: Cassette question

The reason most chain wear indicators are not as useful as they should be is described here. Essentially they measure the wrong thing. For this reason I prefer a ruler. Pedant alert; I would agree that (most) chain wear gauges are not as accurate as they could be because the "wear" they m...

Re: Gear changing strategy; how do you use a triple?

Most of my bikes have 46/34/24 triple, I think there's one with 44/32/22, with 12 or 13 to 34 on the back. <snip> However, to-day I was out on a Spa prototype which was geared for a younger man, 48, 38, 28 and 11 to 32 on the back .....and I hardly got onto the big ring at all.<snip> but I want a c...

Re: "Gusset" under downtube

……...A couple of months ago, IIRC, a poster was enquiring as to the provenance of a far Eastern built 725 frame because of its relatively cheap price. Invariably you get what you pay for and I would expect such a frame to have compromises. It is not beyond expectation that the necessity for a short...

Re: Cassette question

………. There is a saying ‘you can’t teach an old cog, new links’ which is very true, you’ll nearly always get some slipping, initially, when you don’t change cassettes and chains together, as the new pairing re mesh....... Wrong. If you change the chain before it has worn the teeth to change the toot...

Re: set back seat post ?

What seatpost are you using now?
Seatposts with a really long setback are generally expensive.

Re: "Gusset" under downtube

I would like to think that these gussets are fitted with prior attention to the guage of the tube at the lower join of the gusset. The butted section of tubes are often of a set length and the tubes are cut to size to suit the bike. This can leave quite short sections of 'thick' tube and it's quite...

Most of my bikes have 46/34/24 triple, I think theres one with 44/32/22, with 12 or 13 to 34 on the back. I spend too much time on the "big" ring (not so big, really) and I'm trying to train myself to use the smaller rings more and to get into a smaller ring in an anticipatory way, changin...

Re: "Gusset" under downtube

Somebody thinks broken frames won't get billed back to the builder in the Far East, I can assure you they do! Even if the failure was down to the designer? ……….. Designer and builder should be on the same side? If I sent a drawing and the builder said they would build them but not warranty them, th...

Re: "Gusset" under downtube

Fork stiffness is what loads the frame, and its there whether you have panniers and disc brake in use or not. Stiffer to handle the loads of the brake and the panniers, so these forks are generally less tapered than (say) 631 blades. Also the brake and low-rider bosses need to be brazed into a bit o...
