Where can I put them?\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003eThese clamps are designed to go on any tube of the proper size, as long as the tube is straight or nearly straight where the clamp is. In order to get the clamping strength required, the fit needs to be good. If the tube being clamped to is curving, it's not really possible to make a clamp that will fit accurately enough. It would require some even fancier machining, and it would have to be custom made for each curve shape. So, you need to stick to straight, round tubes. Fortunately, that includes most bikes. The clamps are 1\/2 inch (12.7mm) wide, so it's easy to work around obstacles like seat rails and cable stops.\u003c\/p\u003e\n\u003cp\u003e4. Where are the mounting holes relative to the tube?\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003eFor the straightest side to side chainline in the low gears, it's necessary on most bikes and trikes to allow the power side idler to go as close inboard as possible. In order to provide enough thread engagement with the idler bolt, the mounting holes are off the tube centerline. The hole closest to the centerline varies with the size, but it's usually approximately just inside the tube profile. The mounts can be flipped up or down, so the idler centerline can be above or below the tube centerline. For two of the most popular tube sizes, we do make an adjustable mount where the idler bolt can go on centerline as well as quite a ways above or below the tube. In order to do this, the closest the idler can come to the tube is pushed out about 3\/8 inch (10mm). This is usually more than is desirable on a deraileur chainline, but it can work. This mount is primarily designed for geared hub and tandem timing chain tensioning.\u003c\/p\u003e\n\u003ch2\u003eADDITIONAL INFO\u003c\/h2\u003e\n\u003cdiv class=\"tabberlive\"\u003e\n\u003cdiv class=\"tabbertab \" title=\"\"\u003e\n\u003cul\u003e\n\u003cli\u003eMounts are machined from 6061-T6 aluminum and black anodized.

Clean the area of the frame where the clamps will go. Loosen the 5mm clamp arch bolts and remove the arch. Position the main clamp on the frame, then reinstall the arch and m5 bolts.

Chaintube Holder","description":"\u003cp\u003eThe Floating Chaintube Holder solves a lot of problems that come alongside the joys of chaintube ownership. Have chaintube noise problems? Have chaintube drag problems? Have chaintube mounting problems? Well, the diabolically simple and sturdy Floating Chaintube Holder laughs in the face of problems like these. Add in one of our special low noise, extra slippery, virtually indestructible plastic T-Cycle chaintubes and you'll never worry about your chain again!\u003c\/p\u003e\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cp\u003e1. What exactly is this thing?\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003eIt's a way to hold a chaintube in place on a chain, in a way that lets the chaintube float up, down, and sideways with the chain while staying in position front to back. The idea is that the chaintube only rides lightly on the chain, covering the chain where it needs to be covered, and keeping the chain from going crazy without dragging on it in normal operations.\u003c\/p\u003e\n\u003cp\u003e2. OK, I get it, but how does it work?\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003eAs it turns out, the heart of the mount is diabolically simple—it's a section of bicycle chain, turned sideways. Really. After looking high and low for all sorts of industrial materials to accomplish this action, we came back to bike chain. It worked the best of all, but it needed something to make it prettier and keep it from touching things it shouldn't. So we hid it away and protected it from rubbing on anything with a nylon packcloth sleeve. What makes it all work is the laser cut stainless L brackets attached to each end. One attaches to your bike, and the other attaches to the chaintube. Both ends attach with a pair of zipties for easy, secure, and versatile installation.\u003c\/p\u003e\n\u003cp\u003e3. Tell me more about mounting. For instance, where do I put it?\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003eThe first consideration is where the chaintube needs to be. Generally, that's where the chain goes close to your fork, or the crossarm of your trike, or some other part of your frame. Where the mount goes depends on what is within the reach of the flexible chain assembly. It has a reach of 4.5 inches (11.4cm), so there are probably lots of places it will work. The chaintube can be attached anywhere along it's length (front, back, middle, etc.). If the place on the frame where you are attaching the mount is at a very different angle than the chain, the L brackets are designed to be adjusted by bending to get the matching angle. There are notches in the stainless L brackets to catch the zipties so everything stays secure. We put foam cushioning tape on the frame side L bracket to protect your paint.\u003c\/p\u003e\n\u003cp\u003e4. Can I use any chain tube, like the tube I already have?\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003eYes. We recommend using a low noise, soft, slippery plastic. The material we use is quiet, slippery, and very abrasion resistant. Flaring the ends helps with noise quite a bit.\u003c\/p\u003e\n\u003cp\u003e5. It seems crazy that such a simple thing could be the solution to my noisy chaintubes!\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003eI know, right?! There are some other things you don't want to overlook, like the type of material the chaintube is made out of, and keeping the tube as short as you reasonably can, but yes, this is often the key missing piece to finally making your chaintubes quiet.\u003c\/p\u003e\n\u003ch2\u003eINSTALLATION INSTRUCTIONS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAs you approach figuring out how best to mount this, the first thing to think about is where the chaintube really needs to be. Where does the chain rub, or want to rub? Usually, that's where the chain goes close to your fork, or the crossarm of your trike, or some other part of your frame. We recommend keeping chaintubes short, between 4 and 12 inches (10 to 30cm).\u003c\/li\u003e\n\u003cli\u003eWhere the mount goes depends on what is within the reach of the mount. It has a reach of 4.5 inches (11.4cm), so there are probably lots of places it will work. Pick one that leaves a bit of range even at the maximum extent of where the chain normally needs to go. The chaintube itself can be attached anywhere along it's length (front, back, middle, etc.).\u003c\/li\u003e\n\u003cli\u003eIf the place on the frame where you are attaching the mount is at a very different angle than the chain, the L brackets are designed to be adjusted by bending to get the matching angle. The floating action works best if the chain inside the nylon sleeve on the mount is relaxed and perpendicular to the drivetrain chain.\u003c\/li\u003e\n\u003cli\u003eThere are notches in the stainless L brackets to catch the zipties. Usually, it's easiest to wrap the zipties around the tube and tighten them only enough so there is a good amount of slack. You can then slide them over the L brackets, get everything approximately positioned, and tighten them loosely. once everything is basically in place, you can fine tune things before tightening things fully and trimming off the excess. We put foam cushioning tape on the frame side L bracket to protect your paint and give extra grip.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eADDITIONAL INFO\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eChaintubes have a reputation for being noisy, draggy, and prone to filling with chain crud. While this can be true, it doesn't have to be. We think that it's possible to have a chaintube that is very quiet, almost friction free, and unlikely to get gunked up. Here's how to do it:\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003e1. Let the chaintube float with the chain. You want the chaintube to cover the chain, not tell it where to go.\u003c\/li\u003e\n\u003cli\u003e2. Use the right chaintube material. We use a special low noise, extra slippery plastic.\u003c\/li\u003e\n\u003cli\u003e3. Keep the chaintube as short as possible. The longer the tube, the more it will gunk up and the more the chain can vibrate inside. Shorter is better, down to about 75mm (3in).\u003c\/li\u003e\n\u003cli\u003e4. Flare the ends. The entry end is most important, of course, but the exit end makes a big difference too. We flare both ends with a special process that thickens the ends and shapes them for smooth chain flow.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003eIf you do not have chaintube already we can supply lengths up to 4 feet (120cm) long in 4 inch (10cm) increments. We can optionally flare both ends with our special heat process.\u003c\/li\u003e\n\u003cli\u003eSince the inside of the mount is a section of bicycle chain, it is possible to shorten or extend it if you need to. We buy recycled chain from Resource Revival, so the particular brand and type of chain inside may vary.\u003c\/li\u003e\n\u003cli\u003eTrikes like the Catrike may require one or two floating chaintube holders, depending on the position of your boom and the sizes of your chainrings. Basically, it depends on the proximity of the chain to the crossarm and how much the chain is likely to bounce up and down.\u003c\/li\u003e\n\u003cli\u003eThe stainless steel L brackets are attached to the section of chain with stainless steel pop rivets. They are very securely attached, but it is theoretically possible to remove them if you wanted to put in another piece of chain.\u003c\/li\u003e\n\u003cli\u003eThis mount was designed to be very versatile and it's possible to attach it to nearly any bike or trike, recumbent or upright.\u003c\/li\u003e\n\u003cli\u003eIf you have an Xtracycle, for instance, it is a great way to control the bottom chain and keep it from flopping on the ground or rubbing your kickstand.\u003c\/li\u003e\n\u003c\/ul\u003e\u003chr\u003e\u003cp\u003eTypical lead time is 10–14 business days.\u003c\/p\u003e","brand":"T-Cycle","offers":[{"title":"Zipties","offer_id":49314243084532,"sku":"CHM136.1","price":23.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/2634\/2644\/files\/CHM136_02.jpg?v=1788458562"},{"product_id":"t-cycle-chain-tensioner-for-rectangular-tubing","title":"T-Cycle Chain Tensioner for Rectangular Tubing","description":"\u003ch5\u003e\u003cem\u003e\u003cstrong\u003e***\u003ca href=\"\/products\/t-cycle-chain-tensioner-for-circular-tubing\"\u003eIf your bike has circular tubing, click here\u003c\/a\u003e***\u003c\/strong\u003e\u003c\/em\u003e\u003c\/h5\u003e\n\u003cp\u003eThe Universal Boom Adjust Chain Tensioner allows you to move your boom without hassling with the chain.
