Short, but 150m over 1.4km is an 11% average, and parts were worse!<br /><br />http://goo.gl/maps/JgP9JἈντισθένηςhttps://www.blogger.com/profile/06199983680204710885noreply@blogger.comtag:blogger.com,1999:blog-8528686231765021097.post-26749080235820250562013-04-01T23:59:42.376+09:002013-04-01T23:59:42.376+09:00I checked the pic...glad the bell is gone.

I might have to loo...Thanks for the recommendation. I might have to look into it, I imagine changing the cassette wouldn't be too hard. I threw out the box for the derailleur, so I am a bit scared I may screw it up. The compact ended up being the heaviest Campo (2011 model I think) and the rest of my gear is Centaur. I had to change the derailleur as well for the compact.<br /><br />I had a look on Google maps, are you going to go around the mountain to the west? Based on that route, it was just under 24 kms for 1200 m gain. Not too treacherous. Any idea on the slope? The highest I have done is a 1600 m climb (Mt Tsurugi in Shikoku) which was over 35 kms. It took me about four hours, but it was quite a pleasant grade. I did another ride at the end of last year, this time it was a 700 m climb over 9 kms and it was HELL. Some parts were over 25% grade and I was doing about 4 km/h with the front coming up on down-pedal, but I didn't push. Tsurugi was just endless S-bends at about 5-10% for almost the whole way.<br /><br />When you thinking about going?

Also, a smaller chainring is impossible: 34 is likely the smallest you can do, as it probably has a 110 bcd (spacing of the bolt circle). Cheapest bet is a new cassette at about $50 US. Get one with the biggest inner cog your derailleur will take, which is often 28, but sometimes 32. Check online or in a shop. A widely spaced cassette will sometimes leave you in a spot where one gear is too hard, but the next too easy. The best bet is what I did and have it widely spaced at the bottom, but narrow through the middle and top: 11/12/13/14/15/16/18/20/24/28.<br /><br />Good luck!Ἀντισθένηςhttps://www.blogger.com/profile/06199983680204710885noreply@blogger.comtag:blogger.com,1999:blog-8528686231765021097.post-39703699555584420262013-04-01T11:58:28.541+09:002013-04-01T11:58:28.541+09:00What's the elevation for the irohazaka?
Sorr...What's the elevation for the irohazaka? <br /><br />Sorry, I don't change things myself, although I would like to. The gear inches calculation thing is a little overwhelming, but I am rubbish at maths.<br /><br />I got my crank changed from the standard 53/39 to a 34/50 from memory. A smaller rear cassette would be ideal, but my setup is very old now and it was even a bit of a pain in the arse to do the compact crank. Anything over 5% I am grinding, so it would be nice to have one more gear to reduce the strain on the legs and knees.<br /><br />I am really just a complete newbie, I bought my bike second hand from a friend with a knee injury and it just turned out that it is a really awesome bike.

You may be surprised where working harder makes you go slower.Ἀντισθένηςhttps://www.blogger.com/profile/06199983680204710885noreply@blogger.comtag:blogger.com,1999:blog-8528686231765021097.post-9432481977080978062013-03-31T21:47:56.695+09:002013-03-31T21:47:56.695+09:00You keep your hands off it!

Kind of got the wrong bike, but have been fixing it very slowly over the years: should have got this, if it had been available then: http://allcitycycles.com/bikes/mr_pink<br /><br />I like steel, but I also like modern components (integrated brake/shifters, 10speed cassettes...) so I am not a real 'reto-grouch', though see the merit of some of their ideas (shellacked-cotton tape, leather saddles, steel frames...).<br /><br />This is the most recent picture (notice the shit Japanese architecture!), but the asinine bell and frame bag are gone!: http://1.bp.blogspot.com/-g01x9-i_f_Y/UM2UIdZGTrI/AAAAAAAAAM0/uuTNCDOemFQ/s640/20121216182209.jpg<br /><br />Have to get a picture when the new crank is on, and she's 'loaded for bear'.Ἀντισθένηςhttps://www.blogger.com/profile/06199983680204710885noreply@blogger.comtag:blogger.com,1999:blog-8528686231765021097.post-88371639948929825142013-03-31T21:46:24.400+09:002013-03-31T21:46:24.400+09:00"I am a spinner, not a cranker."
I have..."I am a spinner, not a cranker."<br /><br />I have no idea what this really means, so until you tell me otherwise I shall assume it is something <i>filthy</i>.<br /><br />And because the rest of those numbers mean nothing to me, I'll tell you a lifeguard story about efficiency. Every stroke you make while swimming provides propulsion but also creates drag, so ideally you want to take fewer, more powerful strokes. The pool I worked in was, randomly, 33m long. Swimming crawl I'd normally need about 20 strokes per length, while a former youth international on the staff needed low-teens.<br /><br />One regular client delighted us all by needing over fifty. His secret nickname was 'Bath Toy', for obvious reasons. It was always amusing watching new staff briefly panic when they first saw him in action, so similar was his swimming style to the desperate flailings of a drowning man.<br /><br />Still, he definitely got a workout from it, so maybe the joke was on us...kamohttps://www.blogger.com/profile/10785763841038321633noreply@blogger.com
