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...

...the screws and seat post would be exposed to rain and water when the bike is parked up. Will this cause any major issues in the long run? And if so, what is the best way to go about solving it?... Almost always, the saddle clamp should be greased in the bolts and the parts holding the rails, thi...

Re: Spoke calculators!

I wouldn't ask, if it wasn't for the hub / rim being so generic! And I can't get my head around spoke calculators! I'm using a Shimano XT 760 32 spoke front hub, matched to a 32 hole Sputnik rim. Can anyone with more experience advise if a spoke length of 297mm seem about right ! (NB. I've been try...

Re: BB30

...You could have problems that are inherent to the frame's BB shell alignment or the crankset alignment and concentricity... Since the frame shells are usually a machined piece of aluminium, and cranks are machine-made with CNC finish, this is goes well after the wrong number/type of spacers used ...

Re: Dropped seat stays - good bad or ugly?!

Cannot compare a a Pro rider that is used to 150psi tubs and a Team car behind, with the Average Joe who pays the premium for every cycling component. And carbon fiber can be moulded and processed a lot more than metal tubing so cannot make a direct comparison. I.e. in a carbon fiber mould there can...

Re: New chainring. How muuuuuch...?...!!!

The whole thread seems more another rant, than something useful? Truth is a bigger picture than just "the price of one chainring". Modern 10 and 11sp groupsets are not tolerant about wear of single parts, so unless you are very precise with keeping things clean and replacing the chain acco...

Re: BB30

As a rule of thuimb, Sram GXP has the Lh crank (most of their cranks have the fixing bolt on the Lh side) that locks onto the crank axle on a dead-end. This means that the distance between the Lh crank and the Lh bearing is fixed and cannot be altered. In the case of a BB30 if you put too many space...
