IB14: Guru Pushes Photon HL to 650 Grams, Adds Disc Brake Version – Plus Updated Titanium Frames & More!
Already one of the lightest road bike frames out there, Guru’s Photon HL sheds another 20g by reworking just a single tube, and that’s with the addition of a tapered head tube!
Until now, they could claim the HL as a sub 670g frame. Now? Sub 650g, and that’s with paint and hardware. We even put one on the scale to confirm. To shed the grams, they completely re-engineered how they make the seat tube. Before, they would make the seat tube then glue in the insert to hold the seatpost. The insert served two purposes, to create the appropriate inside diameter and to reinforce the seat tube so the seatpost wouldn’t stress it too much or damage it. Now, the insert is rolled into the post as part of the construction process. For a deep look into their amazing carbon manufacturing process, check our factory tour here.
They also introduced the Photon R Disc, bringing disc brakes to their top model, and created an entry level Photon v.4. The Praemio R titanium bikes were also updated with stiffer, lighter and more adaptable rear triangles (with a disc brake option, too!). Even the triathlon bikes get a new baby sister…
