B R A K I N G

On long and steep downhill roads, simultaneously use rear and front brakes to avoid heating up of the brakes.

Excessive heating of the hub with the back pedal brake may result in loss of lubricant and braking too hard. This will lead to a trip to the repair shop.

Read the applicable user manual for each bicycle equipped with i-BRAKE or band brakes.

However, do not use water under pressure (such as pressure washers or water jets) for cleaning to prevent malfunctions due to water penetration.

» During the winter season, you should clean your bicycle in shorter intervals so that winter road salt cannot cause any damage.

» Do not use agressive cleaners.

» Clean dirty chains before oiling.

Let cleaner set for only a few minutes and rinse with water. Do not oil chain until completely dry.

SRAM i-Motion — это серия планетарных втулок, ориентированных на городские, спортивные, туристические велосипеды и разрабатываемых и производимых корпорацией SRAM. Под брендом i-Motion производятся планетарные втулки, манетки и динамо-втулки, а также трещоточные, односкоростные втулки, дерайлерные, гибридные втулки, гидравлические дисковые тормоза. Серия продуктов i-Motion разрабатывается и производится немецкой корпорацией SRAMs Schweinfurt R&D, раньше называвшейся Sachs.

Планетарная втулка Sram i-Motion 3.

Планетарная втулка Sram i-Motion 3 для велосипеда.

Sram i-Motion 3 — 3-скоростная планетарная втулка, имеющая передаточные отношения, как у трёхскоростной втулки Shimano Nexus, 36% интервал между передачами и общее передаточное отношение 186%. Купить Sram i-Motion 3 можно приблизительно за 100 долларов.

Планетарная втулка Sram i-Motion 9.

Sram i-Motion 9 — 9-скоростная планетарная втулка с ростом передач на 14%, 17%, 17% … 17%, 14% и общим передаточным отношением 340%.

Диапазон передач:

Соотношение хода	7,1	6,2	5,3	4,5	3,8	3,3	2,8	2,4	2,1
Передаточное отношение в дюймах	94,8	82,8	70,7	60,2	51,4	43,8	37,4	31,9	27,9
Метры хода	7,6	6,6	5,7	4,8	4,1	3,5	3,0	2,7	2,2

Этот диапазон передач рассчитан на велосипедистов, которые не могут похвастаться хорошей физической формой, имеет приемлемое расстояние между передачами.

Стопорные шайбы для наклонных дропаутов.

Версия с ножным тормозом весит 2400 грамм, тогда как версии без встроенных тормозов весят до 2000 грамм. Стоимость Sram i-Motion 9 составляет около 300-х долларов. Если вы хотите купить Sram i-Motion 9, то вам стоит поспешить, так как эта втулка снята с производства в 2012 году и заменена втулкой SRAM G8.

Планетарная втулка Sram i-Motion 9 для велосипеда.

Трещоточная версия можем комбинироваться с двойной ведущей звездой, например, ведущая звезда 48/38 и задняя звездочка на 22 зуба. Допускается использование ведущей звёзды, имеющей не менее 32 зубов. Существует ограничение на соотношение зубьев ведущей звезды к задней — оно не должно превышать 1,73. Втулка комплектуется удобным поворотным переключателем. По своим техническим характеристикам на рынке конкурирует с 8-скоростными планетарными втулками Shimano.

Планетарная втулка Sram или Shimano?

Какой же сделать выбор втулки — Sram или Shimano (альфине или срам)? Вот сравнение SRAM i-MOTION 9 с Shimano Alfine 8, в котором i-MOTION 9 победила со счётом 5:4:

1. Передачи.
   Если вам нужна бесшумная втулка с лёгким переключением передач, то выбирайте Shimano Alfine. Если вам нужно больше передач с одинаковыми шагами между передачами, лёгкая установка и снятие втулки, то выбирайте SRAM i-MOTION 9.
2. Переключение.
   Обе втулки можно переключать под нагрузкой. Под высокой нагрузкой и на подъёмах из-за конструкции «бесшумного сцепления» с цилиндрическими роликами вместо классических собачек Alfine переключается немного легче и плавней. (Alfine зарабатывает 2 очка).
3. Манетки.
   С помощью манеток Shimano STI за раз можно переключить только на одну передачу, а поворотным переключателем Grip Shift за раз можно переключить всё требуемые передачи. Индикатор передач SRAM больше, передачи на нём лучше читаются (i-MOTION 9 зарабатывает 1 очко).
4. Диапазон передач.
   У i-MOTION 9 на одну передачу больше. На одну высокую или низкую передачу больше, чем у втулки Shimano. (i-MOTION 9 зарабатывает 1 очко).
5. Шаги передач.
   У i-MOTION 9 меньше размер шагов между передачами. Шаги приблизительно одинаковые. На втулке Alfine иногда чувствуется, что текущая передача «маленькая», а следующая высокая уже «больше», чем требуется. (i-MOTION 9 выигрывает 1 очко).
6. Тормоза.
   Обе втулки можно использовать как дисковыми, так и с ободными тормозами (Alfine и i-MOTION 9 зарабатывают по 1 очку).
7. Вес.
   Вес Alfine 1590 грамм. Вес i-MOTION-9 1980 грамм (Alfine зарабатывает 1 очко)
8. Установка и снятие колеса.
   У Sram используется установка в «один клик», как и у Rohloff. Для установки и снятия колеса с планетарной втулкой Shimano требуется некоторое время! (i-MOTION 9 зарабатывает 1 очко).

Манетки i-Motion 9.

i-Motion 9 использует поворотный переключатель, который крепится вокруг руля и конструктивно объединён с тормозным рычагом.

Многие предпочитают триггерный переключатель, который для i-Motion к сожалению не выпускается. Но он и не нужен, так как поворотный переключатель в отличии от триггерного одним поворотом руки переключается не на одну, а на все требуемые передачи.

Инструкция по установке переключателя:

1. 
   Насадите переключатель (1) на руль.
2. 
   Насадите грипсы (2) на руль.
3. 
   Выровняйте переключатель по отношению к грипсам и установите его как вам удобно. Затяните стяжной болт(3). Используйте 3 миллиметровый ключ и вращающий момент 3,5 — 4 Нм (31 — 35 фунтов).

• Для установки грипс никогда не пользуйтесь смазкой или растворителем. Грипсы не позволяют руке соскользнуть с руля и должны прочно держаться на руле.
• Убедитесь, что переключателю и тормозному рычагу ничего не мешает. Иначе придётся их переустановить.
• Никогда не ездите без грипс, так как вы не сможете надёжно удерживать поворотный переключатель. Это чревато ранениями.

Удивительно, но сейчас доступны манетки только с поворотным захватом и интегрированным тормозным рычагом.
