Engagement party location in the New Haven / Fairfield county CT area. I'm planning an engagement party for my daughter in late May or early June. We expect to invite approximately 50 people. I'd appreciate some suggestions for venues, or any feedback you can provide. Thank you in advance for your help.
Chain size is specified by pitch and width. The pitch is the distance between rollers (1/2 on all modern bicycle chain). The width is the internal width where the sprocket teeth fit in. Bicycle chain comes in four basic widths: 1  3/16 (.1875, 4.76 mm), used until the middle of the 20th century on many bicycles; this was inch-pitch chain.
The photo you show is of a bike with a threadless headset; the fork's steerer tube will be a smooth, unthreaded tube and the headset is tensioned with a bolt from the top and the clamping action of the stem. Steerer tube diameter. Also two main options, 1 (25.4mm) and 1 1/8 (28.6mm, also known as 1.125 or 9/8). Nearly all threadless headsets use 1 1/8 steerers. You can verify that the frame you have is for that size by measuring the inside of the head tube, it should be 34mm. If you already have a headset installed, you can verify that the inner diameter of that is 28.6mm.
