Detailed Description

Our ultimate distance saddle features breakthrough suspension. Ideal for cyclists riding more than 6 hours per week and are accustomed to a firm saddle. Custom built. Ti Alloy rails. 298 grams. Women's Model Available. Firm padding. 146 mm width. Reg: $179.95 Our ultimate saddle features breakthrough "tunable suspension." Below the sleek leather and firm padding is our state of the art "tunable suspension." This simple to tune, light weight suspension uses proven elastomer spring technology, allowing the rider to tune the suspension to his or her own personal ride preference.

When bumps are encountered by a traditional frame saddle, the foam compresses, the base flexes and the rails flex. The limitation of this dated design is "one size fits all." Actualy the "one size fits all" is for a 220 lb person. The greater your actual weight varies from this 220 lbs, the less the saddle can optimally absorb bump energy. For lighter riders - especially women - the traditional saddle frame is too stiff. Koobi solves the limitations of a "one size fits all" frame and base by placing an interchangeable elastomer spring between the base and the rail. Softer or firmer elastomers can be installed to soften or firm up your ride.

On a glass smooth road, what you feel is the firmness and shape of the saddle. As roughness is encountered, the elastomer suspension absorbs the bumps energy, reducing fatique to your sit bones, lower back, shoulders and neck. Width of 146 mm (5 3/4").

Each saddle comes with 3 of 4 sets of elastomer springs: extra soft (white), soft (yellow), medium (red), and firm (blue) offering up to 4/10 inch of travel.

Fantastic Saddle!!
Bob Ford (Pennsylvania) 6/2/2010 7:25 PM
I purchased the PRS Alpha at the recommendation of a friend. I was immediately impressed by the great customer service as I ordered the saddle, with the rep taking lots of time to help me identify the best saddle for me and the right elastomers to use. From the outset, I have been very pleased with the saddle and it's great support and comfort. Today I just returned from my first 50+ mile ride of the season, and I'm overjoyed at how well the PRS Alpha worked for me!! No more sore rear end... the PRS Alpha is far and away the best saddle I've ever had... I have used many saddles from many different manufacturers, and none approach the all-day comfort of the PRS Alpha. In two words: highly recommended!

Koobi PRS Review
Alan (New Zealand) 1/27/2010 1:26 PM
After 5 years of training and competing in Ironman Triathlons I have finally ended my quest to find a decent saddle! I have been through 7 different, (very expensive) saddles and hated all of them. I've tried Sella's, Fizik's, SDG's and Vision's and none of them worked for me. I've always got off the bike after a long (6 hour plus) ride with sore sit bones or chaffed bits and had to shift constantly during the ride to get some comfort. In desperation I bought a second hand Koobi PRS and went straight out on a 5 hour ride. The best compliment I can think of is that I actually didn't think about the saddle the whole ride. It's amazing. Thankyou guys - my backside loves you all!!!

No more vibrations
George (Kentucky) 12/18/2009 2:56 PM
I've been riding for over 20 years. My current aluminum bike was almost impossible to ride anywhere due to the vibrations I felt on the roads. I was going to sell the bike cause it had so much vibration. I decided to try the PRS seat before I sold the bike. All of the vibrations are gone that I felt. I can ride without the vibrations, no sore tush and the seat looks so cool. My neighbor is a Schwinn mechanic and tried it and couldn't beleave it. If I ever sell this bike I'll sell it without the seat!! Do your body a favor and ride in comfort.

3rd PRS Alpha on the way!
Anonymous (Unknown) 8/25/2008 1:06 PM
I've been extremely happy with the PRS Alpha saddle design. Whether I'm riding in a time trial, a century, weeknight club ride, cruiser run on the prairie path - the PRS Alpha does it all comfortably. The shape of the saddle and the cutout fit my anatomy perfectly, and offer a comfortable ride every time. I've tried the Bontrager InForm RL, Fizik Arione Wingflex, Selle Italia SLR Gelflow - all of which have ended up on eBay in search of the perfect saddle. The search is over. Thanks to Phil for his premier customer service too, three cheers! Mark Linton - Naperville, IL

A 5 STAR WINNER
Anonymous (Unknown) 8/24/2008 12:20 PM
I am a 67 yr old avid cyclist averaging about 4000 miles/yr. Once a week I like riding a 60-80 mile day in addition to 20's to 40's during the week. A comfortable saddle is a must. I have used this saddle for about 400 miles during which time I fine tuned its tilt to meet my needs. With the understanding that saddle preference is highly individualistic I very much recommend the PRS Alpha. It is a firm shock absorbing saddle which translates into non-chaffing comfort when your butt muscles are "trained". This saddle is still very comfortable even after a long day, day after day. Nice job Koobi.
