Slave Posted June 23, 2009 Author Posted June 23, 2009 Roders, my man, some okes are just hard core. You go up that hill faster than my car can go dude. Respect. If you have the profile Andy, it would be interesting to have Ox compare it to his WWRR. (I am having a ball pulling the piddle with him. Thing is he is doing the same to me.) Longer cranks is an experiment I am going to try. Maybe leave here early and go for a real long one with a few nasty hills to see how we get along. Only thing is, it's very cold with a capital F and windy.
Roders Posted June 23, 2009 Posted June 23, 2009 Slave, don't forget initially things probably wont feel right, the muscle's need to go through a bit of an adaption stage, so give it time, don't turf them after the first ride.
Slave Posted June 23, 2009 Author Posted June 23, 2009 Aye captain. Will persevere with longer cranks for more than one ride. Gotta give it a fair go, but no way ever will I go to a 39 chain ring. May as well start wearing pink blouses then, give up cycling and take up needlework.
GreyOwl3.0 Posted June 23, 2009 Posted June 23, 2009 Slave, as I have said before you didnt use the 39tooth long enough to see the big benefit of it. And, to be fair as someone else mentioned, a 39 is really not needed for any of the Alberton south rides. A 42 will more than suffice.Now, I am not sure of the exact measurements or the means...but I do know that the difference between a 39 and a 42 is significant. As you know, for each revolution of the crank the bike is moved forward a set distance. I remember racing as a schoolboy with restricted gearing and cheating by using a 53tooth chainring instead of a 52. (but you had to use 18mm Conti tires to get away with it!)...the difference between the 53 and the 52 was not huge, but big enough to give you a big advantage over other guys. If you take the same gear at the back (ie 17) and work out the exact distance travelled by the bike per revolution with both the 39 and the 42 and you will suddenly realise why your gearing felt strange! Waffle waffle... However, the whole crank conundrum...trust me dude...the 175mm will make a huge difference. My science is based on the teachings of LeMond, Indurain and Ullrich...
Andyr249 Posted June 23, 2009 Posted June 23, 2009 Sorry so small but was limited to 100KB. But you can get a good idea of the profile.
GreyOwl3.0 Posted June 23, 2009 Posted June 23, 2009 Geez Andy...that hill looks much bigger in real life!!!
Trubie Posted June 23, 2009 Posted June 23, 2009 AndyHow long is that last climb & what is gradient in comparison to the first one?
Slave Posted June 23, 2009 Author Posted June 23, 2009 That WWRR still looks more scary than this. You sure I won't need that crash cart and 180 cranks?
Roders Posted June 23, 2009 Posted June 23, 2009 Slave, once you master the longer cranks, with the 39 ring at front & 21 or 23 gear at the back you will spin that big climb in the reserve with ease, the magical number up there to aim for is 13 km/hr.Fitting a 39 ring at the front has got nothing to do with being girlie or woosie, its about getting up a climb as fast as possible without too much effort as there is always another climb coming to take that bit more out of the legs!!
Slave Posted June 23, 2009 Author Posted June 23, 2009 It's all good Roders. Just having some fun. Going to stick eith 175'sfor a bit and see how it goes. Off to go and try the new setup. Will report back tomorrow, if I can still walk.
Andyr249 Posted June 23, 2009 Posted June 23, 2009 First climb is 2.5km at 8%.The last one I got as 2.4km and 6.6%.But that is starting it when the gradient really kicks up. If taken from the very bottom with the slight uphill it is about 4.5km with avg gradient of 5.5%.
Andyr249 Posted June 23, 2009 Posted June 23, 2009 That WWRR still looks more scary than this. You sure I won't need that crash cart and 180 cranks? Slave, you will need the 180 cranks, a 39 and 28 on the back with a 6kg bike. Even that might not be enough! The climbs in WWRR are not as bad as SBR. Save the crash cart for SBR.Andyr2492009-06-23 08:04:18

If taken from the very bottom with the slight uphill it is about 4.5km with avg gradient of 5.5%. Either way it feels much worse than what these stats portray. And it hurts.
Andyr249 Posted June 23, 2009 Posted June 23, 2009 I think it was just near the end of the ride which made it seem worse. And that you could see more or the scenery which gave you a reference point. That first climb was in the grass and you couldn't see much, except the next turn.
