R+IconR+ V.4 Road, Cross, Gravel Expanded

The R+ V4 from Why

Never look at any dirt road the same way

The R+ extends the limits of what other drop bar bikes can do. The Why engineers optimized this bike for use with 700x40c tires, but gifted it with clearance for 700×50 or 27.5×2.1” wheels. The R+ is extremely versatile: it’s at home on gravel roads and long pavement rides where comfort is paramount. However, don’t let that deter you, speed demons. This bike can hold its own on the cyclocross race track and rides like a jaguar for those of you that want to slap some slick road tires on for super-fast fun. With Version 4, we added a Universal Derailleur Hanger (UDH) and our own carbon fork from our sister company Revel Bikes. Paired with the option to run an internally routed dropper post on this two-wheeled beast, and you’ll be blown away by where the R+ takes you.

R+ geometry

The R+ has a few unique geometry features. Mainly, the bottom bracket drop and the reach. The BB drop affects how a bike corners and, combined with chainstay length, affects it’s stability. On the R+ the BB drop is just slightly more than other similar bikes out there, giving it a more stable, comfortable feel, yet making cornering feel more precise when initiated by the rider. The reach is slightly longer than similar bikes, which eliminates some toe-overlap (hitting the toe on the front tire in tight corners) and also optimizes handling by stealing some tactics from the mountain bike world- wider bars and shorter stems.

Because Titanium is Magic

We make our bikes form the best materials possible for the terrain we ride. For now, that means titanium, but we’re not stopping there stay posted. We use the highest quality Grade 9 3/2.5 titanium for our frames’ tubing, and 6/4 titanium for the head tube, bottom bracket shell, and machined bits all over the frame. The wonder material has so many excellent ride quality attributes: 43% lighter than steel, higher strength-weight ratio than aluminum, significantly more resistant to crash-damage than carbon, and the best vibration damping properties of all three listed here. We think you’ll agree that we achieved our goal of creating titanium frames with a modern twist by engineering guided internal cable routing, stealth dropper post routing, integrated headsets, and threaded bottom brackets. For riders who want a high-end, comfortable, fast bike built to last a lifetime, we believe a properly made titanium frame is the best option.

The Why Bikes


At Why, we believe in our products. If you are not fully satisfied with your purchase for any reason, you can return your Why for a full refund within 30 days of purchase.  Of course, we ask that you respect this policy (no purposely buying a bike for a long term “rental” allowed!)

Further, we offer a lifetime warranty to the original buyer on all Why frames. This is a straightforward warranty policy- basically if you use your bike for what it was intended, and the frame ever fails due to a manufacturing defect, we will replace it for you for free. 

And, to top all of that, we offer a lifetime crash replacement policy. If you crash your bike and damage it, or if you drive into your garage while forgetting there was a fresh new Why on the roof of your car, we will work with you to offer you a replacement frame at a very low cost.
