But I have found myself occasionally losing count and finding the chain at a greater angle than I would normally like without any obvious Ill effects (except maybe not immediately apparent wear and tear).
    I think chains are an engineering miracle. Obviously they stretch and I've just changed my SRAM on the ADV after 1400 miles but at £20 - who cares?, but more than once as I have been standing on the pedals inching up a 25% climb, forty miles from home I have prayed "chain, chain please don't let me down now!

Around 35 years ago, sadly before accurate speed measuring equipment was available, I achieved something similar on the A52 Ashbourne - Derby road riding one metre behind an Irish fish van (which looked more like a removal van) with a very bad gearbox. It was great until the road went upwards and I lost the tow and got hit by the turbulence you would expect from 3 metres behind something of that size going over 50mph. Not recommended

    In short, stick to 52 x 13 or 48 x 12 and spin your legs, (which will help your downhill fellrunning technique), and save your pennies
    Being 100 years old I have stopped chasing fish vans and just want to get up climbs. The smallest gear on my road bike (say 19 lb) is 34/29 and on the ADVenture bike is 32/32 (but 24 lb). The ADV feels clunky and is heavier and I don't really like riding it (I really bought it as my winter bike) but I have concluded that the lower gearing means that even with the extra weight and clunky tyres it should provide an easier ride up steep hills. Pity really because it just doesn't cut quite the same dash as the Italian! (I know I should do a timed comparison but my remaining time on this earth is short!).

    I knew it wouldn't be long before this thread became a new tributary of the grand tidal estuary of factual cycling chat that is 'todays bike ride'.

    As i've been skimming i've noticed someone saying its ok to strain the chain on a 105. Personally, i'd throw the lot in the bin and go SRAM as i've been woefully disappointed with how 105 shifts; especially on the rings. I could scarcely believe my senses when the weather warmed up and i got back on the Colnago which is fitted with DA7800, it was like going from a Trabant to a 5 Series.

    Any news on the TdeY after Mr Verity's surprise departure?

    Crossing the aligator and piranha infested river Orinoco (aka Austwick Beck) on today's 15 miler from home. Note my nobby saddle bag, now at long last carrying a spare inner tube (now that I knew which one to buy )

    Great photo. I'd be on the hoods going through water though but having said that I've not got your biceps!
    Visibility good except in Hill Fog

    I didn't suggest it was OK to strain the chain, just that I'd been told it was but didn't believe it. My 105 is far far superior to the Ultegra I had on an earlier road bike but that's to be expected about a quarter of a century later!
