'Splitter', or an 'Adjuster'

[Richard A Thackeray]

I've been meaning to ask about this for a while, as I can't recall noticing one on other hydraulic disc'd bikes
(then again, I've not really looked for one)
Can't remember my Trek MTB having one - but that's a while ago

Is this just to extend the hose. or a means of adjusting to, maybe, change the lever characteristics?
I'd reckon extend, as it seems a bit silly otherwise (as there's not a rear one)

Looks like a Hydraulic union to me .

No, it is a frame rattler. Actually, you are also right.

Just seems odd, why not simply use an appropriate length of hose?

Without seeing the lever end and routing hard to say .

Usual routing, under bar-tape, then appearing by stem

Then, externally down the fork-leg, to the brake piston

Am guessing space at the levers was a premium . Not seen many disc drop bar bikes .

 

[I like Skol]

My Shimano hydraulic shifters (RS505) have the same arrangement. I always just assumed it was so the bars didn't need to be unwrapped/re-wrapped any time the hose needed detaching or replacing for any reason.

There's plenty of them about, from every manufacturer/'badge-engineered' marque (ie; Ribble & Planet X)

Which I could perhaps understand, but the rear is a single line, with no 'coupling'
