One more thing on the qr levers. When they are closed you may want the lever to be pointing either to the back of the bike or up. On the front I like to have mine pointing up the fork at a light ange toward the back. this way there is enough room to grab the lever to open it. If it is too close to the fork I can not get my finger in between to grab it.
On the back wheel I like to have the lever pointing straight back.
The reason for this is I think it looks cleaner & if it is a mountain bike it will help prevent the lever from snagging on anything. At least I heard it could happen.
