Happy (Bike) Friday everybody! What a loaded @bikefriday All Packa build by @rookey_cyclery ! šŸ” I am sure our humble Cafam levers are keen to be hanging on this versatile bike built with Nitto, Paul and White Industries components.

Our minimalist looking Cafam-S short pull levers and Gordo silicone foam grips look pretty on this fancy lugged Riv Roaduno, which being single speed is somewhat minimalist, too.

Thanks @blackmtncycles for putting our Front Derailleur Fiddler on the field. ā€œSome folks get excited when the latest wireless robot shifing, keep those batteries charged, e-lec-tronic drivetrain drops. Me? I think this is bloody genius. Gevenalle CX f/d IRD f/d Fiddler allows a front derailleur designed for 45mm max chainline to be used on a crank with a 50mm chainline White Industries *gasp* square taper cranks with 38/24 rings.ā€

Before the internet was cool, we developed the TL5 with John ā€˜Sweet Spot’ Castellano and Dave Ijams. (This looks like a preproduction version) It had a novel trailing link design to combat the nose over feel when you braked with normal telescoping forks (Anti-Dive). The linkage met bumps more directly than normal forks, so it would not exhibit stiction like the less stiff forks of the day. The axle would move back then swing up. Suspension and damping were handled by two different diameters of elastomers. The structure was CrMo and aluminum and weighed about 4 lbs, heavy in those days. Funny how no one would bat an eye on the weight now for a shock fork. Manufacturing was done by Hodaka in Taiwan. Clip from Marin Mountain Bike Museum

These fun BMX-tired mini velos were on our feed a lot in 2025. And VO has a lot to do with originating and opening eyes to what is special about this new breed of bike. This hot build features our brake levers and the made in Japan Growtac brakes. Get @reshare_app • @allezlabikeshop The wait is finally over!!! We have finally finished Jameson’s @atwbuilds and @velo_orange Raffelflauge Neutrino!!! While we didn’t win the raffle after spending a whole paycheck on it, we are very thankful Jameson, a very loyal @velo_orange and @allezlabikeshop customer did. He came in with a really good idea of what he wanted and after a few test rides on @kylebkelley ā€˜s neutrino we had it all locked in. Hope y’all love it as much as we do!!! And everyone wish Jameson a very happy #allezLAnewbikeday !!!

@atlas.bicycle - Riding bikes should take the rider to all kinds of places, and one of those places is the Fun Zone! This @somafab Wolverine had been built and ridden as a drop bar bike for many years and miles, but the rider was looking for a change. Enter an IRD MCX monstercross carbon fork and a flat bar and this thing rides like a completely different bike (almost like a 90’s mountain bike). Adding to the change, a @chriskingbuzz headset and @wolf_tooth_comp chainring bring the bike home and give the feeling of a bike that is just as happy tooling through the neighborhood as charging in Marin Co. Every bike deserves a glow up every now and then. #atlassallover #iwishyouanicetrip #irdmcxmaxfork #irdlobocrank #interlocracingdesign

Just a thing of beauty! 🄰 Get @reshare_app • @sourdoughbicycleco This beauty is heading back up to Portland to @prepear2dye . I got to try something on this one that I’d been wanting to do with the wishbone. Super happy with the results. These things take a village to build and I couldn’t do it without help from @bikefabsupply @paragonmachine @6composites and @colorworkspalette
