No, I take it back! But some more info here  Stu. Edited by - sforshaw on 25 Feb 2010 17:29:55 |

I think I need the triple lever. The double lever has some clever indexing that has two positions for the big ring and one for the little ring. I don't think it would work with three rings. It's an ST-7801 lever and the new one is an ST-7803 specially for the triple ring front. At least I hop I'm right otherwise I've wasted £200!! |

Just seen this! For my tuppence worth (after the event, it seems - so here goes!), I still rate the older 9-speed kit extremely highly for these purposes. Shimano (et al) appear to have neglected potential demand for decent low gearing on the 10+speed kit - I really don't know why. I run an Ultegra front triple crankset with mountainbike (XT) rear mech and cassette for the monster Fred Whitton ride (steepest road in Britain pops-up 90 miles in!). Note - if you are going to 9-speed kit from 10-speed, please remember that the front cage design is necessarily different - i.e. you'll need a new front mech (although these are pretty cheap). The rear mechs are completely happy running anything from 7-10 speed as far as I recall. Alex - one thing to look out for (one *hell* of a lot cheaper than new STI levers) is a set of time-trial 'bar-end' shifters. These won't be as convenient for you as the STIs -this kind of thing here here quote: |

Thanks Myles, As you say, I've started down the path of converting to triple. Just realised I can still put a bigger cog cassette in if needed. I just wont be able to use the biggest front with the biggest rear but that's not something I'd ever use anyway. I'll make the conversion to triple and ride it like that for a while and see how it feels. At my level of fitness, the granny ring will be used in the UK as well so not necessarily for just a one off trip. Alex |

Well I was VERY glad I did the conversion to the triple, and truth be told, I was out of gears 1/3 of the way up and could have done with one or two even lower gears, but I got to the top without walking. I did have to stop a few times on the way up which was frustrating but it really is just mile after mile of climbing with heat and some vicious winds to deal with too. The Tom Simpson memorial was very moving for anybody who's seen the photos and film clips of his collapse. As is tradition, I left my water bottle there. I think I'm getting the bug. I'm now wondering when I can add Alpe d'Huez and Tourmalet to the list.... See here for my Garmin data from the ride up and around Ventoux Edited by - Alex Wong on 1 Aug 2010 02:37:56 |
| Simon-R I ought to get out more Location: In and around Oxfordshire | Posted - 1 August 2010 8:44
Congratulations on your achievement, i watched to documentary on Tom Simpson this week and it was an amazing story Simon-R |

Very well done Alex Oh the envy .... 6 weeks ago A group of us rode in Spain with a friend who had started in Portugal and doing around 100 miles/day finished on Alpe d'Huez - just the 50 miles I did in Spain was enough to wet my appetite to do more continental riding! I'm so jealous of what you've achieved! Now, must try and source a Campag triple ... Stu. Joint Area Representative MAD Sevens (Merseyside And District) www.superse7ens.co.uk..........the rebuild  |

Congratulations I did Tourmalet witha group of friends the other year when the TDF was there. I cheated, and went up on an MTB shod with slicks - loads of low gears!  Only dead fish go with the flow....! |

Well done, I'm very impressed you cycled all the way to the top!quote: I'm afraid I've got a hybrid with those gears just for use in England Edited by - DJ. on 1 Aug 2010 23:23:42 |

Well done Alex Hell, I run 28 / 34 as bottom gear in the South East; goodness only knows how much lower I would have to go for proper mountain roads. |

Thanks chaps. It's definitely one thing ticked off my TTDBID list. Halfway up Mt Ventoux, wishing I was a couple of stone lighter and alot fitter! Edited by - Alex Wong on 2 Aug 2010 00:33:23 |
