Offered in Small or Large, this is the thickness of the grip in hand.  The Small and Large are the same length and have the same wing size.  The only difference is the thickness of the grip in hand.  Riders with smaller hands are best to choose the Small size.  Riders with large hands are an ideal fit to the Large size. Ultimately, choice of size is a rider personal preference.

Standard: 2 full length grips

Why bar ends?
Bar ends offer the rider additional hand positions.  Bar ends also allow greater leverage when pulling on the handlebars.  Ergon offers its bar ends in various length to suit the demands of all riders.

Happy hands that rest on the GP5 BioKork's.

very comfortable and easy on the wrists

Biokork or not; the wider platform provides a more comfortable base and more riding comfort for the longer rides. The forward horn handle gives more riding positions that help with hands, wrists, shoulders, back and crotch positions facilitating more comfort. Not only yes but, hell yes!

Makes riding more comfortable

The size and quality of the grips are perfect and I enjoy the hand position options they offer.

Best grip I've used on a bike to date.

These things are just wonderful! Three well thought out hand positions, made out of sturdy and comfortable material. Completely transformed the ride feel, and on top of that they look cool too!

Comfortable Grip, Uncomfortable & Brittle & Expensive-to-Replace Bar Ends

I've used Ergon GP grips on 2 of my mountain bikes, these GP5s on a Trek 1120 bikepacking bike for a year. I've been working to really dial in the bike recently, and so doing some intensive riding. I'm finding that my hands are still going numb with these grips after a couple dozen miles. Tweaking the angle of the grip slightly to keep my wrist as straight as possible helps but doesn't entirely eliminate numbness. But all in all, happy with the grips themselves.

The bar ends are another matter, tho. I've always loved bar ends; they are a great aid for climbing and should offer additional hand positions. However, these bar ends have never been confortable, nor really functional. They are just angled wrong with no way to correct it in 3D. They twist in a single plane at the end of the bars, which for my bike does me little good. So my wrists are at odd angles on the bars, absorbing too much shock.

Worse, my bike toppled over while doing some tweaks in my kitchen, and one of these bar ends simply broke. Which tells me that they are not up to the demands of touring AT ALL. Worse still is the difficulty replacing these. Ergon defers to local dealers. My local dealer (REI) doesn't have parts. Parts online, including at Ergon itself, are typically sold out at the moment, and are sold individually. So the net effect is that you're buying a whole new set of grips as the least-cost option to fix a part that should never have broken so easily.

I plan to step back to a GP2 end which hopefully won't break so easily. And future purchases may not include a bar end at all.
