Looking Good, keep up the hard work and enjoy the ride. I to have an Alur 700 but its fairly standard as it come from the shop. I have done about 200 miles on it so far and its been a good treat. Thankfully no punchers yet. A mix mode of road and cannel gravely routes have been not bad. Id like to ask the key differences with your upgraded Crankset: Shimano 105 5800 to the standard Comp1 Crankset it has on their? Is peddling now been improved ? I am new to all this so please bare with me. I am not as clued up as some of the users here. Thanks J The 5800 crankset improved shifting a lot. The Pro Wheel crank isn't that bad but with the 5800 shifting feels much better and is more silent. Do you still have the ten speed at the back? or have you changed it to 11 speed for the new crankset you have ?

Only part I changed on the group set has been the crankset Shimano tells you shouldn't do this but its working absolutely fine.

The length of the crankset depends on the size of the Alur. On my S sized one it has been 170mm (center to center). You may also change the length to fit your measurements. But if you feel fine with the current setup you can also stay with the same size. The length on the comp1 should be visible on the inner side on one of the cranks. Or simply measure it by your own (From the center of the bottom bracket axle to the center of the pedal axle) I would highly recommend the 5800 version. It is lighter, stiffer and looks better No reason to take the outdated design of the 5700 one. Even the new Tiagra got the new design!

I was told from one of the bike mechanics at decat that putting the new 11 speed 105 crank on a set up which has 10 speed will cause shifting problems. i am not sure how true this is but he made it sound believable. have you had nay problems in shifting using both front and rear gears ?

No problem with shifting. I had to adjust die front derailleur slightly but since then shifting is absolutely smooth.

Just to play devils advocate here, why change a perfectly good lightweight crankset that functions well to one that is pretty much identical in weight?
Why not wait until the chainrings are worn then go for ultegra?

Why not wait until the chainrings are worn then go for ultegra? Aesthetics? Just to have a complete groupset? Can always sell the existing chainset to claw back a few quid. Lovely looking machine.

The Pro Wheel crankset is just fine, but the 105 from Shimano is better

Please excuse my ignorance but isn't the 5800 crankset 11-speed but the shifters are 10-speed? I too am interested in replacing the crankset.
