Not familiar wiht the Giant Rincon but these fit my Specialized Rockhopper.

I couldn't fit them over the rubber grips, I had to take off the grips and cut off the end and then attach the bar ends.

should fit the Giant without any probs, no you cannot fit hem over the grips, you will need to move your grips, levers etc inward slightly aprox 20mm

They have to be mounted onto the actual handlebars, sans grips i.e. you will have to move the grips inwards or shorten them.

You'd be better off cutting off the relevant length of bar grip so that the grip on the bar studs could engage with the metal on the handle bars, makes for a much cleanerr look as well.

they fit any mtb handlbar, well at least the older ones, and your '08 model should be OK. No, move the rubber grips in a bit, and fit bar ends over the bare aluminium bit

They fit on any standard diameter handlebar, but you'll need to either trim the grips or shove them about half an inch (a centimeter or so) along the bar before clamping the bar end onto the end of the handlebars by tightening the bolt with an allen key (don't overtighten!).

Not sure about your Giant Rincon...

But no, I didn't tighten these over the rubber grips - I moved the grip inwards, and clamped the bar-ends onto the handlebar end directly over the bare metal bar. Inside diameter of the circular clamp is approx 23mm on mine, when fitted. They would also fit slightly larger I think, up to about 26mm OD handlebar...

I would imagine these would fit almost all handle bars, I fitted mine to a Giant Anthem X4. You don't fit these over the grips, you would need to move the grips inwards (by first moving brake and gear mech...loosen using an allen key). You then tighten the bar ends with an allen key - simpulls!

They should fit your bike but I had to move the rubber grips on my Giant CRS3.0 2008 along the handlebars (and the gear and brake leavers too) to make room for the studs.

74 mm protruding from bars, or 107mm overall.

this will depend upon your positioning of the stud, it can be fitted to any "height" you like

Beacuse the bar studs are adjustable the height of the final fit is down to you and your persoanl requirements. Best to try out a few different heights to see which is best for you.

depends what you want, i set mine about horizontal, so Zero.
I recommend horizontal or close to it, pointing up is dangerous I think

G'day,
Once fitted there is about 72mm of bar-end for gripping on to. The total length from backside of clamp to bar tip is about 105mm. :-)

74mm prodruding from bar or 107mm overall. Sub 60grams each in weight.

75mm , not sure of weight

sorry, did not weigh mine, but then they are just simple aluminium bar ends, expect ok weight, but tough.
Length, approx 10 cm

Didn't weigh mine, sorry. Length wise, they are approx 105mm from bar tip to the back of the clamp end - ie. total overall length.

Once fitted, there is about 72mm of bar end for effective gripping.

from the centre of the bar to the tip of the bar end they are 94mm (don't forget they bend slightly inwards). From the top of the handle bar to the tip of the bar end they are 71mm - sorry, I can't weigh them

no too lose, bad design
