Re: aluminium bars - 3 year life?

I do not see how filling the handlebar with foam would significantly increase its stiffness, especially since most of it would be wasted near the tube’s centre where even metal does little for stiffness. Are you sure we’re not confusing this with foam under the handlebar tape to make Paris–Roubaix ...

Re: aluminium bars - 3 year life?

i'm sure i read somewhere that filling metal tubes with foam type substances increases their resistance to bending. maybe that type of thing would help a cracked bar hold on that bit more? Bianchi? maybe yes. backstedt's roubaix frame of several years ago. on reflection i'm not sure that 'stiffer' ...

Re: Road bike tyres - how long / far before replacement ?

what are the conditions where tyres wear most? running at low pressures? climbing? accelerating? braking? rough roads? cornering? i trained on a big fixed gear one year for practice as a tandem stoker, maybe 55 x 14 or something like that, using a 25c marathon on the back and a continental gp3000 on...

Re: aluminium bars - 3 year life?

i'm not sure that all 10,000kms are the same, nor are any 3 years in the life of a 'bar. despite being fairly robust i think that i'm pretty light on bars as i tend to ride on the tops and climb whilst seated so i'm not thrutching and twisting them so much. most of mine are 20 years or more old and ...

real world difference - front lights

i have a good front wheel generator hub on my commuter bike and it runs a cyo light that, i think, has an output of 60 lux. it's really pretty good at lighting the way on unlit roads. the beam throws a decent distance and seems to be a good shape. i read that there is a similar light that makes 100 ...

Re: SPD cleats removal

i only have one pair of SPD cleats/pedals. no idea which model (although it never dawned on me that they'd be different width pedals for some reason #smackshead.)

what's the meaning of the capital 'M' on the rear tab on each cleat?

Re: The timeless appeal of 7-speed gearing

"Maybe if I weren't too old I'd try a single-speed, fixed gear, or penny farthing" i've never quite understood this. when is this age? and what's so demanding? or is it from that TdF quote about the use of derailleurs from years ago? in reading the thread yesterday i realised that i've nev...

Re: Does anyone still use down tube shifters?

i like the way that you can pick up slightly older bits of kit like DT levers for pennies these days. https://www.ebay.co.uk/itm/Vintage-NOS-80s-Campagnolo-C-Record-8-Sp-DUEL-Friction-Syncro-Shifters/264089651553?_trkparms=aid%3D555017%26algo%3DPL.CASSINI%26ao%3D1%26asc%3D20160706105120%26meid%3Dba5...

roughening rear wheel dropouts

in spring/summer i commute on an old 531 frame that has had the rear triangle manipulated to accept 130OLN rear wheels (currently in the shed awaiting said times - not far off in an optimistic type of way.) now maybe it's slightly off, or maybe chain lube drops onto them, or maybe i'm such a climbin...
