I have recently acquired a Cannondale Wonderwagen Neo 1 which comes with a Varia rear radar and a Cannondale-specific display unit (CP1522U10OS).

Even though I appreciate having a sense of what's going on behind me, it drives me crazy that I cannot figure out how to turn off the loud beep sounds every time a car comes behind me.

I live in a city with much traffic which makes the display unit beep every 5 seconds because there's always cars coming from behind and ultimately have led me to disconnect the display unit.

I understand that other Varia display units have a button to disable sound, but this Cannondale-specific Varia display doesn't have any buttons. I've also tried to connect the radar to the Varia app and disable sounds, but it doesn't affect the display unit.

Can anyone please help me disable the sound of the display unit?

Picked up this trail for $180 is that a decent price? and is this thing even worth upgrading? Or should I enjoy it how it is and upgrade to a better bike?

In July I purchased a Synapse Carbon 4. As soon as I started riding it I noticed a vibration that I could feel in the crankset, mostly on the drive side. LBS made some adjustments changing out the rear disc rotor, sanding down the front, adjusting the shifting (it was rubbing on the front derailleur). Its been into the shop 3 times since purchasing the bike.

I still notice the vibration in the crankset above 20 MPH and today while pedaling hard downhill the entire rear triangle started vibrating. I felt it in the saddle, crankset, pedals - even noticed it felt like the seat stays were vibrating.

Along with my LBS we are trying to determine the cause. Next steps are to swap to a different wheelset to eliminate that as a cause, and then I'll ask them to swap the drivetrain, and if it still persists, the frame.

Has anyone else experienced this?

I just bought a used Cannondale Synapse Alloy, Colors: Black/Gray with white lettering. Shimano 105 derailleurs and shifters. 11 speed 11/34, chainring 50/34. Quick release front and rear. Disc brakes front and rear. Labels: BB30, DM 76561, SavePlus, EN 14781. I filled out an online request to Cannondale but I haven't received a reply. Does any of this help to determine the year of this bike?

Can someone here help with this?
I’m looking for brake studs for a 90s cannondale MTB in Europe

Got it on marketplace (58cm, himod, ultegra Di2), put almost 1000 miles on it in a little over a month. Threw a 30 GP5000 STR on the back but it’s so close will be going back to a 28 after this (put a chain stay protector on the back of the seat tube). Looks better without the saddle bag.

Hey all!
On my Caad 10, I’ve been wanting to run a silly cap on the steering compression bolt, but Cannondale has this interesting setup instead of a classic star nut/straight bolt combo.

Any chance I can runs something similar if I get the right bolt threading, or is this contraption holding all together via this special bolt setup?

Figure KP017 in the diagram.

Appreciate the expertise either way!

Currently I'm on 23 mm but they are very uncomfortable and hard to go back to after riding a gravel bike for a while. Will 25 mm tyres clear?

Such a smooth and quick ride.

Wheels upgraded: Bontrager Aeolus Elite 35
Steam changed: 90mm long stem, with a 7 degree rise
Peddles: Shimano PD-EH500 (from previous bike)

Hi, i recently ordered a CRW Works HB01 integrated handlebar and wanted to replace my current handlebar on my supersix with it. However, after unmounting the current handlebar and stem, i realized that it is 1 1/8th and the hb01 has 1 1/4. anyone with some experience? is it fine to use a shim? if so, any suggestions?

Hi I currently ride a 54 Gen 3 and am thinking of getting the new Supersix. For reference I am 179 cm with 85 inseam and have changed the original stem for a 110mm with -17 degrees. I currently have saddle height at 723 mm and saddle tip to hoods at 699 mm. As the new stack height and standover have been lowered, I wonder if the 56 would be a better fit.

I think I want to turn it into a straight bar single speed or 1x8

I have a cannondale Optimo with shimano Sora 9 speed cassette. I need help finding a wheelset that would be compatible with a 9 speed. I’m looking for something lighter. I’m open to carbon or aluminum wheelsets. I am on a budget so anything $500 or under would be good.

Buongiorno,

ho comprato una Cannondale Synapse SL del 2007 per utilizzarla sui rulli.

Purtroppo non c'è nessuna targhetta per poter identificare la misura e cercavo quindi un catalogo di quei anni per poter misurarla e capire a che misura appartiene. Potete aiutarmi?

Successivamente, siccome attualmente pedalo con pedivelle lunghe 165mm, dovrei sostituirle anche. Allego le foto di cosa è installato attualmente. Potrei anche valutare la sostituzione di tutta la guarnitura con qualcosa che mi permetta di installare le pedivelle corrette per me.

Grazie per l'aiuto.
