Re: Deep Rim/Short Spokes vs. Shallow Rim/Long Spokes

i'd be at least as concerned about tyre choice. just wouldn't fancy a quick lossy puncture when ripping downhill at 50+mph. but does that mean new tyres? or something newish with a few hundred miles on them to scrub off the outer surfaces. FWIW i'd go with shallow rims for the wind cheating effects ...

Re: Titanium seatpost that is all titanium

I have a Chinese one that I think is all Ti. The clamp most certainly is very very tough, so not a cheaply alloy. Bolts were Ti and crap. Thanks, do you have a name for it or a link? Try xacd.com . I have a titanium frame from them, purchased in 2005. Still in good nick. They do titanium seat posts...

Re: Crank Length - formula?

170 mm cranks cannot be right for riders 155 cm tall AND for riders 195 cm tall One wonders whether the majority of us are using cranks of the wrong length why not? Why do you need absolute efficiency 100% of the time in every single aspect? Crank length is so tiny in terms of importance even at th...

Re: Crank Length - formula?

why would a crank be 6 and 5/8ths inches in the first place? seems an odd amount. old english crank, with cotter pins etc. Came on my first 'racing' bike so got demoted to the training bike in time. cheers i just wonder why someone would choose *that* length and not, say, six and a half etc. looks ...

Re: 30 teeth sprocket for 8 speed Campag cassettes

i'm still running two bikes with campagnolo 8 set ups. the commuter one uses DT levers so if the hub or rear mech dies then i'll be okay using a shimano wheel or similar. the other runs '96 ergos and has a frame with no bosses for DT levers. going to be expensive methinks when the rear hub or ergo o...

Re: Handlebar tape (and gels ?)

i appreciate all that chief (and i ride on manchester's finest roads so have encountered the odd imperfection or two) but if the hands are resting more lightly on the bars then they don't get shaken about so much. just a thought.

Re: Handlebar tape (and gels ?)

i never really understand the comfort element of bar tape as my hands rest lightly on the 'bars so pretty much anything will do. looking for extra shock absorption makes me think that the bars are in the wrong place, maybe too low.

i look for grip on bar tape. especially on the drops.

Re: Fixed gear chain wear

It may or may not be relevant but the one and only time I bought a Wipperman I found it rusted in no time and I went back to my default SRAM in disgust. I have a theory, with no proof so it is just a theory, that one of the hazards chains face is thorough removal of oil / grease with a solvent, fol...

Re: Fixed gear chain wear

dura ace fixed chain rings are 1/8th no? is it a track one? i did the exact same sort of thing many years ago. fitted a wippermann chain expecting some sort of endurance outcome with the thing but it melted within a month / 400 miles of mixed weather. have never bought another. over many years ridin...

different types of threadlock

i never have had cause to use this in about 40 years worth of playing with bicycles. the tiny centring screw in my front brake caliper keeps backing out so i want to keep it adjusted in. has a 2 or 3mm allen key fitting in the end. now i know there are different types of threadlock but which to use ...
