STAFF QUOTE
"This bike is a super playful long-travel ripper with 29ers that are ready to take on anything you can throw at them." - Henry, Bike Mechanic
FROM THE MANUFACTURER
Transition's Sentinel is designed for inspiring confidence and achieving the technical skills you've been waiting for.
It’s forgiving do-it-all attitude truly blurs the lines between planted bottomless sender and playful poppy trail pony. Whether you’re chasing EWS dreams or just a weekend afternoon escape, it will bring out the best in you. So easy to get acquainted with you’ll find yourself sending lines, jumps and maneuvers you always felt were beyond your ability. Where before you went around, now you go over. Where you pushed up, now you pedal. Where you rolled, now you boost.
FEATURES
Lifetime Warranty
At Transition Bikes we take pride in the quality of our products and are stoked to offer a lifetime warranty for the original owner and our stellar crash replacement program. We got your back so you don't have to worry about your bike.
Carbon Construction
Full carbon frame made from premium Japanese Toray fiber with a tailored blend of 24T and 30T materials to create the right balance of frame stiffness, strength, and impact toughness. Our unique latex coated EPS molding process allows for sharper frame lines and tighter edge radius control with maximum strength to weight ratio and less wasted material.
Technology
Collet main pivot technology improves rear end stiffness and keeps your pivot hardware tight. Additional bearing shields prevent main pivot bearing contamination when washing your bike or riding in wet conditions.
Badass Bearings
We exclusively use EnduroMAX suspension pivot specific bearings in standard sizes that are readily available worldwide. Dual bearings are used at the dropout pivots for frame stiffness and additional c-clips lock the rocker bearings in place under torsional loads.
Accessory Mount
Our underside top-tube accessory mount allows you to carry a spare tube or other goodies safely on your frame in case you are looking to ditch the backpack.
Seatpost Insertion
Dropper posts keep getting longer so we combine short seat tube lengths with mega seatpost insertion to help get your saddle completely out of the way.
Clearance
Ample clearance for mud and tires up to 2.6" width.
Friendly Cable Routing
To simplify maintenance and keep your bike noise free, the rear derailleur cable is routed through guide tubes in the front triangle and chainstay.
Threaded BB
A standard 73mm threaded bottom bracket shell makes crankset maintenance hassle-free and prevents unwanted press-fit BB related noises.
In Headset
Our ZS44/ZS56 press in headset gives you the freedom to use angle adjust headsets if you feel the need to make your bike a touch slacker or a touch steeper.
Angleset headset does not come with framesets or complete bikes.
Bottle Compatibility
We keep your water bottle clean inside the front triangle so you can keep hydrated without worrying about mud making it to your mouth.
GEOMETRY& SIZING
Speed Balanced Geometry
SBG ensures the bike maintains low speed agility, front wheel traction, and proper rider weight balance while actually increasing confidence in steep terrain and at high speeds. With SBG, a slacker head tube angle is combined with a all new reduced offset fork standard, preventing the front wheel from being too far in front of the rider. This improves front to rear weight distribution on the bike, which is often out of balance on long and slack bikes. One of SBG's greatest benefits is that it creates a confident steering feel that adapts to wheel speed. More stability when going fast, more agility on technical slow speed maneuvering as well as improved traction, control and confidence for any skill level of rider.
