Re: Stripped headset thread - time for a new bike?

To have done such repair doesn;t mean is a good thing to do, weld material is not a good canditate to cut threads onto.
Let alone finding someone that can actually cut a thread onto the forks

Re: MTB toe clips - difference/advantages?

That won;t give any advantage when pedalling ,and the "protection" will be minimal, if any.
Better off with some nice flat pedals, more freedom and more traction too.

Re: Is this (disc brake adapter) going to be OK like this?

Put it this way: most Mtb forks for XC are not rated for 200/203mm rotors, that says all!

Re: Downtube Shifter

Will any LH friction downtube shifter work with a Shimano Tiagra 4500 front mech? Mostly, yes. The travel on a double-chainset is not that long so almost any Lh friction shifter will do. The problem arises when the shifter is not able to hold the tension. That is the reason why old Shimano thumbshi...

Re: Planet X brakes Pinch bolt

I've lost one of these pinch bolts. Basically it's an Allen bolt that pinches the cable through an aluminium holder, like this photo bottom left. Of course Planet X no longer supports the product, so no joy there. Any ideas where I can source this or something similar? I know this design was made u...

Re: Going Italian - B/B repair?

I’ve got a couple of frames with jiggered b/b BSA threads in which I’m running the square taper threadless b/bs - these seem to work fine, the first one tried to come undone but has settled down. You do need the two Shimano tools to nip it up tight and thread locker presumably helps. I’m getting in...

Re: Going Italian - B/B repair?

FWIW as an engineering approach having two RH threads in the BB shell is a bit crap really. It is. The Italian threaded bottom bracket on my steel Pinarello once came unscrewed as I was happily cycling along. If was that crap, there would be milions of italian cyclists lost up in the mountains :lol...

Re: Derailleur Hanger alignment tool ?

Old Thread Resurrection Whilst pottering in the garage today, I came across my 'collection' of old fixed sprockets, and it struck me that an alignment gauge (nb not a tool for bending the dropout) can be built using a track hub. I've found a 'fairly hooked' 1/8 fixed sprocket to which I'll attach s...

Re: Stripped headset thread - time for a new bike?

Much cheaper, more elegant solution: buy a pair of threadless cro-mo 1 inch chrome forks. Available online from £50-100. The above solution welding/threading is going to be significantly more expensive. Why bother when you can have a brand new pair of shiny chrome forks. Decent Ahead stems from a t...

Just a frame might be worth considering.

Re: Anyone Using Alligator (aka Fish Bone) Cable Housing?

They call it "Alligator" cable housing. It snaps together. It's expensive. It's 50% lighter than standard housing. It can't be used on internally routed frames, because it won't fit in the tubes. Similar stuff (called TRLREQ ) can be got from China, 1900mm of these metal pieces for about ...

Re: BB30

Not all shells are aluminium. As you know, moulded shells are increasingly common. Not all cranksets are equally well machined. One-piece carbon shells for BB30 are (thankfully) very rare, more common for "press-fit" nylon cups (whether using 24 or 30mm ID bearings). And the discrepancy i...
