Hi martha,

Great photo, thanks, makes your question very clear!

As you guessed, you do not have the X-Low extension mount. It's very similar to the Low mounts you have, but not identical.

The X-Low should be available through any Cervelo retailer.

Nice extensions on the top in your photo. What kind are they? They look like they could be quite comfortable!

Cheers,

Here's a pretty detailed review of the hack you'll need to do. http://dinosarti.com/...k-out-of-my-di2-9070

The 9070 parts are super easy to find as Shimano is shifting everything to the new e-tube system. It's the older 7900 stuff that is basically discontinued now. You can buy the extra set of TT shifters and the cateye buttons now and have the hack completely done in advance. Then when your bike shows up, all you'll need to do is plug them in and mount them to your bike. Good luck.

My first couple of P5 rides outside this past weekend, and it was epic. 50km in the pouring rain to a 10km trail run race, then 50km back home. 8 degrees Celsius made it cold, miserable...and perfect to HTFU.

Now, on to the P5 part of the post. My aero bars are not staying put in the Aduro bars. My LBS torqued the collet nuts, and after a short ride outside a week ago, I torqued them some more, using an adjustable wrench and rag to protect the cosmetics. They are tight enough that I am afraid of breaking something by over tightening them, but they are not staying put.

After my ride on the weekend the aero bar extensions have ended up rotated slightly in the Aduro bars. I cannot easily rotate them back, so I'll loosen the collet nuts and realign them, but I believe that they will simply move again with any sort of hard effort while pedaling.

So - any tricks or ideas to keep these from moving?

I had thought about putting a couple of small dabs of tubular glue on the extensions before inserting them, but it is messy stuff and it could make for problems when trying to remove the bars if necessary for service or transport.

Suggestions welcomed...thanks.

I have the nuts cranked as tight as I am willing to, fearing that any more will strip the threads or crack the nuts or threaded bar end.

What to do? The bars keep slipping, and right now I am pretty much unwilling to race on this bike as it's dangerous. I'm constantly having to adjust the bars while riding, and if I'm not careful, a little bit of rotational force to realign them moves my bike sideways (think of pulling on the handlebars - of course you'll change direction!)

Am I the only one with this problem?

The Adura Bars have an integrated 90mm stem and 25mm fore and 25mm aft adjustment for the arm pads. The 51cm Three should ship with a 70mm stem for a 51cm. Please keep in mind that 'specs may change without notice,' meaning; if we had a shortage of 70s, we might ship with a different length.

Hi Nick,

You can use as many washers as you like as long as you still get 6 full turns of the nut engaged.

But be sure the cover will still fit. The brake is designed to fit very close to the frame, and if you add spacers it may move the brake into interfering with the cover.

It's easy to check, just hold the cover in place over the brake and look inside.

Cheers,
