Re: Why We Cycle - Film on Dutch cycling culture.

If you have Amazon Prime then it is a free film at the moment.

Correction: These are on the Freshtripe web site where it says they fit both downtube and bar end shifters made by Dia-Compe and Shimano.

Re: DIY touring shifters; stem/bar centre mounts

In my bits box I've got these mountings for down tube shifters.

No branding on them but I think they are Velo Orange. Can't remember how much I paid for them but I know I wouldn't have paid Paul Component/Rivendell prices :) .

Re: Google maps

More usefully, every council I've ever looked for has an online version which you can usually find with a simple "<council name> prow map" search. Thanks for the tip. My local Hertfordshire Council has a "Rights of way - definitive map" page which leads to a version of Google Ma...

Re: Wellgo LU-974 pedals - which is front?

It's such a vestigial pedal flip that I can't see it being that much use, especially with that reflector in the way. There is a bolt-on MKS Spin-2 Pedal Flip which might be more effective for any folk that like this sort of thing.

Did you ever try the CJ "Cluster Method" that he recommended to you? Works for me, once the penny dropped how easy it was.

Re: Fixie: Why?

For: Near total silence when on slick tyres. An other worldly experience when out in the countryside. Against: 1. Having to brake more on steep hills. 2. A couple of incidences when squeezed into the gutter by overtaking HGVs who thought they have passed me. I feared that a pedal strike on the curb ...

Re: Bluemels Mudguards fixing puzzle

Ah, that makes sense - a bolt head with "wings" to engage with the cut outs each side of the circular bit of the hole so that the bolt wouldn't turn. Just a pity they weren't supplied with the mudguards!

Bluemels Mudguards fixing puzzle

I've been fitting a pair of Bluemels mudguards that I bought 8 years ago (26", 53mm). All the SKS/Bluemels mudguards I have fitted in the past have two holes at either end of the fixed bridges to take the stay and eyelet bolt: IConventional.jpg These Bluemels mudguards have just one oddly shape...

Re: 650B (584) Tyres and Rims list resource

I have DT Swiss 465 D 650b disc brake rims 32h with inner rim width 19mm. Tyres are Schwalbe Marathon Performance GreenGuard wire bead tyre 42-584 (650x40B) which I measured as 39mm wide.

Re: What type and length of rivets?

So many ways to skin a cat! In the past I've used pop rivets with a backing washer and then used the snapped-off rivet shaft to knock out the steel head trapped in the rivet. Once that steel head is clear you can drill/file/hammer the excess rivet material to a low profile.

Re: What are those really narrow washers called?

The V-brake washers I found were a bit tight in the seatpost hole. Rather than scrape powdercoat off as I tightened the screw I enlarged the hole in an M5 washer using a grinding stone bit in a Dremel type tool. Third attempt sucessful. Not wanting to apply too much force on them the first two washe...

Re: What are those really narrow washers called?

I was after an M6 washer. Following Brucey's suggestion I have found a couple of suitable washers in a bag of spare V-brake convex/concave washers.
So, immediate problem solved but I'm still left with the niggling thought that these washers must have a generic name.

What are those really narrow washers called?

You've seen them. Usually under seatpost screws and stem screws where the washer outer diameter is the same diameter as the socket head cap screw. They aren't covered by the Form A - Form G range. I thought one of these washers under my seatpost screw might be good practice. I can use the brutal tec...
