Usually, I time circular saw trials with my homemade timing rig made of a straightedge with start and stop microswitches embedded along one side and wired to a hacked stopwatch. Unfortunately, in this test, I had enough saws that would not guide true against a straightedge so the rig couldn’t be utilized. A few saws pulled away from the guide and missed the second switch. Others ran in toward the guide and ground to a halt.

Spring has sprung. The temperature is rising. And tops are dropping, as convertibles start to emerge from winter hibernation. Take this Fiat 124 Spider Urbana Edition, for instance.

Pro Tip: Get into the habit of loosening your chain at the end of the day. Cold weather can cause it to tighten as it cools and damage parts.

Do you have any ideas on what the root of the problem may be? I never experienced any vehicle with this problem that couldn’t be fixed in all the years I worked as a mechanic, and I did an extensive amount of brake work.

We could learn so much by just trying to adapt the Bermuda bus system. But we are a brilliant people, with a unique culture, so we will do it our own slow and backward way.

Jason’s new 1991 Carrera C2 is a classic slammed custom. Jason went through the effort of replacing the front headlights, fogs, and amber corner lamps with OEM Bosch originals. The rear tail lights were refinished, painted, and cleared, paired with new gaskets, and installed to clean up the tail end of the car. The pitted and weathered windshield was replaced with OEM glass. After the restoration came modification, and first on the list was a set of AH Exclusive H&R coilovers. This allowed him to plant the the body of the car just over the pavement while retaining the the drive-ability and handling you expect out of a 911. After dropping the car, Jason added 5-spoke twist design wheels which are synonymous with Porsche.

Roundabouts are becoming increasingly more popular in Canada but I do agree that as a Canadian driving here for more than 20 years I know there are too many North Americans who can just rent a car and have no idea of how to drive on the left but are given the keys with zero education of Cayman driving rules and off they go. Wrong.

The drop section of the black aluminum handlebar has a mild flare, the stem is forged aluminum. The slotted saddle has a short nose and wide rear, similar to the Specialized Power saddle.

I see from James Huang’s review that even if it could be programmed, the different chain size and teeth profile mean this wouldnt work anyway. Seems like a lot of money for something which isnt compatible for anything else…

The new V6 and 8 speed transmission where avaliable on 2017. 2015 and 2016 Colorado have the 6 speed, that people like you dont like.

Coolest detail: Triple down tube. We’ve seen twin down tubes before—Colnago’s BiTitan frames in the 1990s, and more recent examples from Factor—but this is the first triple down tube we’ve ever seen. In place of a single 32mm down tube, there are three 16mm tubes. “I was curious to see if the frame rode any differently,” he said. “[There] is about a 33 percent greater contact area between down and head tube this way.” O’Donnell reports that the bike rides quite well after extensive testing, which included sprints, gravel rides, and “meandering my way home after dinner and drinks.”
