- Di2 problems
It’s still under warranty so hopefully shouldn’t cost me anything. It is frustrating though as it’s the first time I’ve had something wrong with any of my bikes that I’ve not been able to diagnose and fix myself.
… and I miss my bike 🙁 I wonder when visiting hours start tomorrow?Posted 4 years agomikewsmithSubscriberMr Blobby wrote:
Well it’s been hooked up to the diagnostic computer and had its software upgraded and now it’s all magically working again. The chap at the shop was at a loss to explain why it wasn’t working in the first place. Bit of a concern!

the 11 speed Di2 with the USB port will only allow firmware upgrades.
it will not allow access to the diagnostics package. this requires the SM-PCE1 kit.
we’ve had a number of customer with firmware problems the past few months. Its normally sorted with a firmware update.
Be aware that some shops will not know how to do this properly, which may have caused the ongoing issue. Unless the mechanic has been trained by Madison / Shimano it may be hit and miss if they actually know what they are doing. I have seen instances where mechanics have “skipped” parts of the full procedure.
We’ve also had several customers with faulty STI shifters, either from a hard crash (requiring purchase of new shifters)
or just an electrical fault has developed into one of the micro-switches. Madison have always sorted this under warranty quickly.Posted 4 years ago
Thanks eshershore. I am tempted to get hold of the diagnostic interface thingy as it’s been the first time I’ve had a problem with any bike that I’ve not been able to fix myself and it’s pretty frustrating.
I’ve really liked having Di2 as when it works the shifting is brilliant, but this is tarnishing the experience somewhat. I now feel like I’m just waiting for it to fail completely, probably while out on a long ride.
My money’s still on either a dodgy micro switch in the shifter, some sort of stickiness in the rear mech or as an outside bet, a loose connector. Back to the shop this week 🙁Posted 4 years agoesher shoreMember
the SM-PCE1 is actually available for consumers to buy, despite what some bike shops have been telling riders
if you have bought a Di2 equipped road bike, and want to be able to maintain your bike at home (and have a PC) I would ask the dealer to sell you the Shimano kit at a reasonable price so the shop makes a small profit
(I guess this would be around £150 bearing in mind trade price, VAT and shipping to dealer and the dealer’s admin time to order the item)
the full diagnostics access is brilliant, the best example was the 2012 Paralympics (spelling?) where we had a lady who asked us to switch the rear mech shifting function to the left shifter as she found it hard to use her right hand on a constant basis. I won’t say who she was, but it was awesome to see her on TV and the results she got 😉
the 1/2/3/constant shift function is also clever to suit riders needs.Posted 4 years agoTurnerfan1Member
I had a similiar issue with a friend’s bike.Check all connectors.Pull them out and press them back in.My friends bike had a loose connector at the brake lever.It did move again which was fixed with a bit of electrical tape! I believe the hand movement on the bars had somehow moved it back out of the lever.There is a junction box near the bb which may involve removing cranks to get too.I would try connectors at Mechs and levers first.Posted 4 years ago
