di2

Hi All I am starting to get pretty annoyed with my bike. I am getting failures of components far too frequently in my opinion. I've had my bike (an Enigma) about 2.5 years ago and I have done just over 12,000 miles on it. I am a heavy guy and have been between about 210 and 250lb during this...

Apologies for the dumb question but just picked up my new bike with di2 and reading through the manual. It states, "don't remove the rear wheel without turning the lever switch off" Can anyone confirm this is only for mtb versions as I can't see a lever switch on the road version TIA

My brother in law bought a lovely Merida reacto 7000-E late last year on sale for around £2200. Unfortunately it was stolen the other day and looks likely the insurance will pay what he paid for it. Only problem is it's no longer on sale and this years model is £3200! Has anyone spotted any...

Looking for my N+1 and am now considering going for Ultegra Di2 as opposed to mechanical Ultegra. What are the pros and cons of going for Di2 over the mechanical version?

hi I currently have a 11-32 cassette and I've have noticed these guys with much smaller rear cassettes and they take off at the ligths. What cassette can I put on my ultegra di2 group set to pick up speed as quick as these guys. Do I have to adjust the stop screws.

I am swapping my pro-compact 11-28 for a compact with an 11-32 cassette. Cassette is on order as are Rotor chainrings, however am I right in thinking that the short and medium cage 6870 Di2 mechs themselves are identical apart from the cage length itself?

Does anyone do the updates. i have gust read you can use the charger to update the firmware through your PC. Was going to have a little play, Has anyone done it? And was it successful.

I've a 9070 DuraAce Di2 setup on my bestest bike. It's been fine for 18 months but has now developed a very strange and difficult to diagnose intermittent problem. I'm putting this out there to see if anyone has had the same problem and, if it gets fixed, as a record of WTF caused it. Here's as...

Hi all ... I'm struggling to make up my mind on the group set for my new bike that i will be ordering soon ,it would be interesting to hear from any other owners who have either group sets fitted currently , been watching reviews on both & still unable to make my mind up on what system to go...

Apologies if this has been asked previously but I've looked everywhere for this online and can't find it anywhere and I have nothing in my documentation on this I've recently taken ownership of a Specialized Roubaix Pro with Di2 (a prize from Zwift and Specialized...) and I can't find anywhere...

Ok this question is a little late as we are well into winter but i was on my turbo the other day in the garage (not allowed inside :() when i looked across and saw my other road bike equipped with di2 ultergra this got me thinking should i remove the seat which has the battery in and bring...

I noticed last night that the left hand main lever on my Ultegra lever is sticking - it shifts OK but doesn't return to the normal position afterwards, I was having to manually push it back. I seem to remember that I had the same thing happen last winter, but got the lever changed as it was...

Bought after an RTC wrecked last carbon bike. Not been fit enough to take full advantage and now my neck and back prefer a more upright posture. Ridden approx 200 dry miles. Like new. Medium frame. £2000

Anyone tried it? It's shimano's (new?) automatic gearing for a hubdrive - As I understand it very similar to an automatic car gear box, it measures how hard you're peddling and shifts up and down gears appropriately. I'm considering an electric tandem with the OtherHalf who isn't a strong...

Hi guys A mate of mine has ultegra di2 with a 11-28 cassette, he wants to change the cassette to 32t he has a short cage derailleur so will need to go medium or long Can the rear derailleur just be swapped out or will it need pairing in some way or even plugged into the laptop, I'm hoping...

i have two bikes The lightweight carbon bike with sram red/force and carbon rims, disc brakes Or the Custom Ti with sram rival with a 1x11 drive train, handbuilt hsons and disc brakes Now i have the chance after my hols of getting ultegra di2, but i'm struggling to decide which bike i should...

I have recently constructed (with the help of a friend) a road bike with Shimano Di2 Dual Control shifter set (ST -R785, 2 X 11). However having set up the disc brakes, the free stroke distance of the dual control levers is quite some distance before they bite..in fact the bite occurs just...

Hi I just installed a d-fly sensor on to my di2 ultregra set-up so i can see which gear i'm in and battery levels on my garmin head unit. I noticed whilst doing this i have to double click to shift the gears past the third largest gear on the why up the cassette and twice at the third smallest...

Okay, I expect this to be a minority concern but; how often do Di2 owners actually plug the damn thing in? I've had mine 900 miles/5 months (it was an ex-demo unit and took about 15 minutes to charge/top-up when I received it) and have resolutely refused to plug it in since, if only to confound...

Hi, I have the ultregra 11-speed di2 set-up on my bike. I am looking at adding a wireless ant+ (Ewwo1 unit) unit into the system so i can see battery levels and gear selection on my garmin head unit. I'm confident i can install this myself and looking at installing in the bottom bracket as i...

Hi, I turned up for a sportive at the weekend got a mile down the road and hit the first hill so I hit the left hand lever to change down to the small ring on the front and nothing happened. The battery was charged and the rear mechanism worked perfectly. I did the whole event without a small...

Thinking of changing to Ultegra Di2 after the summer and will most likely be do the install myself. One thing that bugs me about the di2 set up is the Junction box under the stem. Iv seen many pictures on various social media posts where they have managed to hide the charging/JB somewhere else...

Hi All Im having problems syncing my Garmin Edge 1000 to Di2... It seems like a straight fwd process; switch garmin on, go to setup; select sensors then Di2, operate gears (as per the instructions) and hey presto.... nothing. Has anybody had the same / similar problems and what did you do to...

Hi guys, I have for sale a Giant Propel Advanced SL ridden by John Degenkolb himself at the end of 2015. Now, you might wonder what I’m doing with this beauty, the fact is I won it in a competition a few weeks ago. The problem now is that because it’s Degenkolb’s actual bike I couldn’t choose...

With my annual bonus due I have spent weeks browsing new bikes. I have even flirted with quality second hand. However having never actually a brand new bike I am leaning towards going new. Ideally I want disc AND Di2. However in my c£2.5k budget it's impossible. Unless you know otherwise...

Having got reet back into road cycling this year, I'd been pondering a few circa £3k plastic bikes. I appreciate that like most of us, I'm a weaker link than the bike, but if you can, you will. First up and on the radar for a while was either a Canyon Ultimate CF SL 9.0 Di2, except the colours...
