Re: Park Tools chain wear tool - changes in newer version?

Or do you mean this one...? https://www.parktool.com/product/chain-checker-cc-4?category=New%20Products I've not seen that one before...Sort of the same but different..... The new one looks like the old Shimano TL-CN40 & TL-CN41 type where roller wear is eliminated from the measurement because ...

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. (As I noted in a previous post , as well as 42-584 Schwalbe have marked the tyres as 26 x 1.6 which if you follo...

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...

Or they then lend it to someone else and expect you to go chasing after the third party to get it back. :x

Re: Quick Link (removal) tool - experiences / recs ?

BTW some folk have re-used supposedly non-resuable links (eg for chain cleaning) and I have not heard of any breakages arising, although they didn't come apart easily. I wonder if the instruction that some manufacturers provide, saying you shouldn’t re-use their quick links, is there solely to stop...

Re: Bike Stand

I have a pet hate to see people putting a bike upside down; the bars, saddle and brake levers always get scratched. Yuck. I'm with you on this one but, OTOH, I find inverting a bike does have its uses. For example, if you have mudguards then inverting the bike does give you the best view to inspect...

Re: Bike Friendly Degreaser

I deeply regret using white spirit to clean an old Witcomb frame. The Reynolds 531 and Witcomb decals began to lift off. :(
