Cockpit
The cockpit places your hands: handlebar, stem or one-piece cockpit, headset and bar tape. Choose it first on your current position, then on the cable routing.
The cockpit places your hands: handlebar, stem or one-piece cockpit, headset and bar tape. Choose it first on your current position, then on the cable routing.
The cockpit sets two measurements: the distance between the fork steerer and your hands, and their height. For the first, add the stem length and the handlebar reach: a 100 mm stem and an 80 mm reach put your hands about 180 mm from the steerer. A handlebar with a 73 mm reach on the same stem brings them 7 mm closer, without changing anything else. Measure your setup before ordering, and compare each handlebar on these measurements rather than on its width alone.
A separate handlebar and stem adjust independently. An angled stem can be flipped: at 100 mm with a 73° head angle, a flipped 84° stem raises the handlebar by about 20 mm and brings it about 6 mm closer. An integrated cockpit hides the housing and removes a joint, but width and length are moulded in: only the height can still be adjusted, with spacers.
With hidden cables, the housing enters the frame through the top of the headset. So the headset decides which cockpit fits, hence the adapters for each headset brand. Ritchey's Switch system routes the cables beside the bearings, and its spacers open at the front: raising the handlebar by 5 mm means neither cutting a hose nor bleeding a brake.
On the road, a 3 mm bar tape keeps the feel of the handlebar under your palm. On gravel, where the vibration lasts for hours, 3.6 mm bar tapes damp more, in 2,300 mm rolls to wrap wide, flared handlebars.
Not always. An angled stem can be flipped, raising the bar by about 20 mm for a 100 mm length, and spacers under the stem raise it further as long as the fork steerer is long enough.
An integrated cockpit hides the cables and is a single piece, but its width and length can no longer change. A separate handlebar and stem can each be adjusted and replaced on their own: the right choice until your position is settled.
Measure the stem from the centre of the steerer to the centre of the handlebar, then look up the reach and width of the handlebar in its manufacturer's specifications. Compare widths at the same measuring point: at the hoods, at the start of the bend or centre to centre, depending on the brand.
