Rated 4.6 out of 5 by 32 reviewers.
Rated 5 out of 5 by Typical XT quality Quality, reliable front mech. Shifts well and requires little attention. 03 October 2014
Rated 4 out of 5 by Great derailleur Very light for the price and good quality. The only thing is it the cable comes from the top it won't be aligned with the frame. That look odd a bit but it work great. 21 September 2014
Rated 5 out of 5 by Отличный переключатель. Без лишних эмоций. При покупке велосипеда сразу поменял переключатель на XT. Ни разу не пожалел. Работает исправно. Если у кого что-то там лопнуло или треснуло скажу, что и стальные рамы ломаются. Тут все зависит от наездника. Такие дела. 28 August 2014
Rated 2 out of 5 by не понравилась рамка Катаю круглый год, к механической части переключателя претензий нет. Не понравилась сама рамка! Как тут уже писали буквы XT не нарисованы а впрессованы на самой рамке из-за чего, на мой взгляд, рамка теряет жёсткость. После нескольких экстремальных моментов с последующим попаданием цепи между звездой и рамкой обнаружил прогиб рамки как раз в месте букв, самое слабое место. Через некоторое время стала гнуться в нижней узкой части, ну и после пары правок лопнула в месте изгиба и отвалилась окончательно. Проехать успел на нём 3500 км. в том числе по зиме, механическая часть работает исправно, всё двигается как надо, не люфтит. 14 August 2014
Rated 5 out of 5 by Прекрасная работа После перехода с алтуса на ХТ не могу нарадоваться. Переключения точные и четкие при любых условиях, хоть дождь, хоть грязь. На сильном морозе немного отзывчивость падает, но думаю, что и топовые модели замерзают. 30 June 2014
Rated 5 out of 5 by GREAT PRODUCT great bit of kit what you expect from shimano and the service and delivery from crc is top notch would recommend 25 June 2014
Rated 5 out of 5 by Good end reliable works flawlessly, good price for the quality, I replaced with it the crumbling Shimano Deore 14 June 2014
Rated 5 out of 5 by Cheap and working well I don't know where is the top but this stuff is working very well even on dirt. 27 April 2014

Answer: 
The diameters refer to the seat tube diameter that the clamp will fit. They are all 34.9mm as standard, but supplied with varying shims to suit the different size seat tubes as required.
E/DM suggest the E-type/ Direct-Mount style of derailleur, which is held on by the bottom bracket cup or mounts directly to lugs on the frame. They are usually listed separately to the standard clamp on style

Answer: 
As the Vitus Gravir Frame Specifications says, Front Derailleur Band Size: 34.9mm. So everyone fits your frame! There comes also varying shims for other options, but you dont need those.

Answer: 
As User-Camppis has stated, the 34.9mm band size is what is required; making any option usable.

However it would be best to select the 34.9mm option so there is no need for any of the shims and the fitting will be tighter.

Answer: 
This is the Top Swing (Low Clamp) version as pictured and coded; the M771 (linked below) is the Conventional (High Clamp) style.
Both mechs are dual pull so you can route the cable in from above or below as dictated by your frame.

Answer: 
This derailleur is compatible with your bike as long as it matches the seat tube sizes available. The design is different because the clamp and derailleur body are closer to each other.
