"The K-Edge Pro Road Braze-On Double Chain Catcher is a must-have defence against nasty chain drops. Why let an expensive frame get damaged for the sake of a few $s more!
The Catcher is very smart looking, SUPER-LIGHT, and easy to fit. It gives plenty of adjustment variables and unlike those single bolt catchers the K-Edge Pro Chain Catcher employs leverage with a two-anchor design.
I note some of you had issues with rounding the hex screw. I took care to follow the instructions carefully and had no problem at all installing this item on my Cannondale Supersix Evo Di2.
I've been spinning it now for some time and NO PROBLEMS with plenty of PEACE OF MIND.
My frame set is stealth black with red logos and the red K-Edge Pro Road Braze-On Double Chain Catcher complemented my colour scheme perfectly.
A great product HIGHLY RECOMMENDED, honestly."

"This DA FD replaced my Ultegra Di2 10 speed when I was upgrading my drivetrain. The Ultegra was great but this is just that bit better.
It is, of course, lighter. It has the Dura Ace look. Fitted to the braze-on anchor the unit is amazingly rock solid.
Unlike this FD, the Ultegra Di2 cable point surprisingly sits at such a position as it will cup and hold water. This could potentially cause electrical faults in the Di2 system. The Ultegra Di2 version will not have an issue as long as the cable is firmly sealed. The Dura Ace FD goes one better, it has its cable point where it cannot cup water, thus avoiding the potential water issue.
There are also subtle improvements in speed adjustment and auto-trimming in this Dura Ace FD compared to the Ultegra equivalent. That improvement, however, is not significant.

There are also subtle improvements in speed adjustment and auto-trimming in this Dura Ace FD compared to the Ultegra equivalent. That improvement, however, is not significant.
From the 2nd generation Di2 system onward Di2 components are interchangeable and do 'talk' to each other flawlessly. This is something even the Pro's do in professional tours.
The 'brains' of the Di2 system is the Rear Derailleur, as long as the firmware in the RD is updated and configured correctly you can mix and match levers and FDs and even RDs. Thus you will see an Ultegra medium cage RD and a Dura Ace FD on Pro-Peloton bikes in the recent 2014 Giro. In fact you can use your Ultegra Di2 10-speed FD and 10-speed levers with an 11-speed system. The key will be your RD's configuration. Of course, your cassette and chainset and chain will have to match your 10 or 11-speed set up.

Choose the correct pads for your wheels and enjoy fantastic braking power increases both in the wet and the dry.

They are super-flexi and simple to feed through your frame [if you are using internal routing].
Other reviews tell you some plusses but you would not believe how robust these cables are. They can be almost crushed and still operate. They can be snared in component clamps and flattened to 0.2 mm and still work. In drenching downpours or in searing sunlight these cables just work.
In short, they are almost indestructible.

"No one should complain about this cassette. The price is phenomenal.
Very little separates the Dura Ace cassettes from the Ultegra, though there are differences. However, at the price of the Ultegra cassette why would you not buy it!
I have been running these cassettes for some time now and they are fantastic. A great buy."

It is 'rock solid' holding the GoPro safely and without any movement.
But that is the problem, you may wish to reduce camera shake on your recordings and a rock solid mount will increase the shake from road vibration. Shake can be reduced by bolting on a vibration-reducing mount onto this mount if shake is too great.

"I was worried about swapping out my Ritchie Pro Stem for the ARX Alloy Stem. The Ritchie Stem has a full wrap-around form and I was worried about the ARX equalling strength of the full-wrap form of the Ritchie. I was also somewhat concerned about the Ritchie faceplate design over against the ARX's.
My fears were ill-founded. The ARX is super-light, so strong and confidence-inspiring. A plus was the reversible form to suit a very aggressive or more upright position. The ARX Stem is also very stylish complementing my bike superbly. And the price from Wiggle for the 120 mm ARX Stem was superb.
If you want a light, strong, stylish and affordable alloy stem the ARX will fit the bill.
Thank you Wiggle and 3T."

Sizing of SIDI compared to Mavic Shoes
Hi,
In Mavic Zxellium Road Shoes I take a 43.1/3 which oddly translates in the chart to a UK9. I say oddly because I commonly wear a UK8 [depending on the brand].
If I were to purchase a SIDI equivalent that appears to translate into an EU 45, a size I have never worn. If this is accurate SIDI's shoes must be small made?
One does not wish to send shoes back and forth with associated extra cost.
Since I wear the Mavic 43 1/3 what size would you advise I should buy in a SISI shoe?
And would I need to bear the return postage cost if the shoe size was wrong?
Thanks for any guidance you can give.

Why is the washer not flat at the back as advertised?
I bought the chain catcher and found out that the washer has got a curve on it therefore not suitable with my band clamp (as I have a braze-on derailleur) that has a flat front. The picture showed on your website that it has a flat back and that's the reason I bought it. I know that the radius washer would suit some frame, but how hard is it to include both washers? What's even more silly is that the Pro chain catcher with the radius washer is not compatible with K-Edge's own band clamp as it's flat front. What do I do now?? Spend more money to get a compatible band clamp, or put the chain catcher into the bin? Hmmm... hard decision

Tiagra swap to Ultegra

Top 100 Contributor
This will be fine as your 10-speed shimano hub will work with the 10-speed shimano cassette.
You will be increasing the largest sprocket so you will have to double-check your chain length.
Note, it is not best practice to use a worn chain on a new cassette. The wear on the chain will shorten the life of your new cassette.
Also, give your hub a clean down and a wipe with anti-seize paste.
Enjoy.

Just rode a few hundred yards on my new bike which have the stock pads from the Ultegra BR-6800's and the braking in the wet is appalling!
Top 100 Contributor
Yes, and these pads will transform your braking on your alloy rims.
Be sure to choose the correct option for your rims, either alloy or carbon surface.
Never use the same pads on alloy and carbon rims as minute fragments of alloy in the pads you used on your alloy rims will potentially destroy your carbon rims.
These pads are superb and worth investing in.

This DOES work. I have just done it. One thing is vital; all components must have the latest firmware update and must be configured to 'talk' as a system. This is something your local bike shop can do for you. My LBS did it free of charge.
Generally speaking, all the electronic components are compatible between the Ultegra 6770 and the Dura-Ace 9070 systems [except the Sprint Shifters]. This means that all of the road bike Ultegra/Duar-Ace dual control brake levers/shifts, time trial shifters, and climbing shifters can be used with either Ultegra 6770 or Dura-Ace 9070 front and rear derailleurs. Any of the Ultegra/Dura-Ace controllers (A Junctions) can be used with either system. All components use the same cables and connectors.
Thus, an Ultegra 6770 10-speed system can be converted to 11-speeds by replacing the RD-6770 with the Ultegra RD-6870 or Dura-Ace RD-9070 11-speed Rear Derailleur. None of the other electronic hardware components need to be upgraded. However, an 11-speed compatible rear wheel, sprocket hub body, sprockets, and chain will be required. Firmware will need to be upgraded.
Hope this helps.

Super narrow lightweight Ultegra 6701 10-speed directional chain for optimum cassette and chainset interaction and maximum power transfer (recommended for use with double systems only).
Would this fit a 53/39 and a 12-30 on the back?
Top 100 Contributor
I'm running the 'compact' on the front and the 30 ring on the back and I had to remove 4 links from the chain. If you are running a Medium RD that, coupled with your big front ring, may demand a couple of extra links. It should be okay. But at Wiggle's price just bag a a couple of these, they are that good!
