Re: Yet another reason to avoid carbon frames

"... that there is some kind of assumption that the weight saved by using CF is in some way significant. Sorry, it ain't..." Yes it is. Sub 9 stone. Extreme copd, lung age mid-90s. 17lb carbon with lowered triple, 10 -20% quicker (Or same speed for less effort). Thats he crux of it for me...

Re: Crank lengths !

The formula in the original post is gobbledigook. :evil: E.g. My inside leg is 36" or 91.44cm. Multiple by 1.25 gives 114.57cm. Add '65' (I assume mm) gives 116.85cm. So my crank length should be 1.16m then, or longer than my actual legs..... Didnt even get an level in maths then :lol: 91.44 x...

Re: Crank lengths !

Thanks every one for responding to my question There's some great advice been given and interesting experiences as well. I just assumed , and it appears wrongly ' that the longer the crank the bigger the lever. Just to experiment last night I ordered a 170mm Crank Set which I will fit to my Trek Mad...

I would have thought that a bigger problem would be to get a frame that fits such a short person :D

:lol: Oh come on 5' 10 " isn't that short :wink:

Crank lengths !

Browsing through Youtube videos about crank length I found one that recommends a formula to use to determine the correct length and i would be interested in learning of forum members view on it. You use your inside length measurement ie 81.28mm x by 1.25 + 65 which gives me a measurement of 166.6 mm...

Re: Front Derailleur positioning

If the big ring's on the wrong way round, is there a large peg sticking out of the 'ring which is catching the chain and pulling it as shown upthread? The peg is designed to stop the chain falling off between the chairing and crank arm. Also note some front mechs don't like a 10 tooth difference be...

Re: Front Derailleur positioning

The big ring is on inside out. Look at the middle ring, which is on correctly. It has a slope or ramp facing inwards, that helps the chain climb up from the smaller ring. The big ring has the same feature but you have put it facing out where it can't do its job. Thanks pea every days a school day :...

Re: Front Derailleur positioning

Hi, I just went thru a similar problem a new 11s Athena? Campy triple mech with a Sugino chainset 48/36/24, The inner cage plate would contact the middle ring, when the front mech was positioned so the outer cage plate, cleared the outer ring by a few mm, per the Campy install document. I had to ra...

Re: Front Derailleur positioning

I think my tourer currently has the mech well above the recommended 3mm clearance on the big ring. More like 10mm. It finished up there after adjusting it to get it to change nicely on the smaller two rings. It doesn't chuck the chain off so I'm not worried. Perhaps you end up with it like this if ...

Re: Front Derailleur positioning

Hi everyone just removed chain set ( whoever invented the Stronglight system which only needs a Allen key to remove it gets my vote) and then the BB. The BB is 113mm and looking at the Spa web site they recommend 110mm. So now another question given I have got a 110.5 BB could I get away with fitti...

Re: Front Derailleur positioning

Did you change the middle chainring when you changed the outer? If not, my guess is that you now have a 'sub-optimal' step (tooth count difference) between mid and outer CWs for that FD. You may need to increase the size of the mid chainwheel. If you swapped to a new chainset, has that change alter...
