Re: Dawes Ranger 22"

Maillard hubs should have clearly visible date marks on them.

[edit; 'not being used much' is clearly the understatement of the century; that bike looks like it has never been used much to me; the rims barely look scuffed from the brake blocks..... :shock: ]

Re: Gearing question for recumbents.

....And any tendency to approach those gears would be betrayed by stiffer rear mech lever and more transmission noise anyway... Not so. Most modern derailleur systems will quite happily select the big-big combination and on a recumbent it will probably run OK anyway. I don't plan to use big-big on ...

Re: Brompton cycles choices

there are various options for bags but the Brompton B bag is probably the one that is closest to what you need. This has straps/handles as well wheels built in, so the package can be wheeled about with the bike inside. However even when folded the bag is a bit large for carrying on the bike, so migh...

Re: Gearing question for recumbents.

I am not convinced by Tigerbiten's large to large being necessary. I would never run that combination. If you cannot run the big-big combo and shift into it by mistake then something breaks ........ :cry: And you're most likely to make that mistake when you're cold, wet and tired, exactly when you ...

Re: Does tyre pressure make so much difference

FWIW I have found any Marathon rear tyre to get incredibly draggy if it is run below about 50psi. They are usually sufficiently stiff that you don't feel that the tyre is that soft until you measure the pressure. With some of these tyres you have a choice between fast and a bit jiggly, or comfy and ...

Re: Shimano FC-T551 chainset spares

lots here

of which some are 10s and should work OK for you, eg to fit FC-M670 should work OK I think.

Re: Front and rear derailleurs for my retirement present (to myself)

FD-R3030 is designed to work with the matching FC-R3030 which has an 11T gap betwixt middle and big rings. It will probably work OK on a 10T gap. It comes with a set of plastic shims to make it fit a variety of seat tube sizes. Fundamentally there are two readily available sets of FDs that might wor...

Re: Velo Orange Grand Cru Seatpost.

it is for the benefit of the frame. The bending moment in the seat pin near the collar is the same, so it is pretty much just as likely to fatigue (if there is a given amount sticking out the top) regardless of whether there is a good amount of insertion with a long one or not. I have seen several f...

Re: adjustable pin spanners

in use, there is virtually zero force trying to open or close the tool. Thus there is precious little advantage to having a locking adjustment.

I had a similar scissor action tool and I had to grind the jaws to a new shape to make them fit some parts.

Re: Front and rear derailleurs for my retirement present (to myself)

I think a (complete?) list of 9s XT rear mechs (in order of introduction) runs thusly; RD-M750 (H,T) RD-M760 (L, T) RD-M751 (H,T) RD-M761 (H,T) RD-M770 (L, T, nb) RD-M771 (H,T, nb) RD-M772 (H,S, nb, 36T) where H = high normal L = low normal T = two sprung pivots S = single sprung pivot ('shadow' typ...

Re: Healthy drinking bottle.

one of my chums uses a Klean Kanteen bottle; this is all-stainless steel and whilst it doesn't entirely solve the 'lets eat road dirt' problem, it does address one of the other common issues with bottles, which is that they tend to develop their own, uh, 'biosphere' inside and are not always easy to...

Re: Front and rear derailleurs for my retirement present (to myself)

RD-M771 will be fine. Same cable pull in all shimano 9s rear mechs! The difference between 771 and 772 is the 771 is a twin-pivot design and the 772 is a single-pivot design. IIRC the 772 has a slightly larger capacity. You should be able to track down a NOS 9s XT front mech if you keep looking, and...

Re: Dynamo system choices

they stopped making the S6 and S12 models some years ago, and have more recently stopped making the more basic Dymotec 6 model. It is still in stock at some retailers; I provided a link to it upthread.

Re: Front and rear derailleurs for my retirement present (to myself)

provided you have a barrel adjuster in the cable run somewhere, (eg on the ergo bosses) I would recommend RD-M772 XT rear mech. It is 9s compatible so you can run it in index mode from 9s shifters if you so desire; it will accept a 36T bottom sprocket, and will work very well provided the biggest sp...
