That's a good point, I may change it if a new plastic hinge is a bit beefier but for now the stock one is way to wimpy. As for cost I'm not sure, it took me about 1hour to make it and would probably change a few things on the next one...I wont be going in business any time soon, it's really just for fun.The only downside would be in a crash or in the unlikely event of something getting tangled up in there is that it won't break. the hanger is designed to act like a derailleur hanger and break a $4 part before destroying the $50 part.
The shrink wrap is not a bad idea, although its probably unnecessary . Only problem is that you would have to either cut it or break the chain when the tube starts wearing and you need to rotate it to prolong the life. If you remember to rotate it and flip it every once in a while you can get a ton of life. I have been running the same one for a year now and am just now considering putting a new one on.Heat shrink wrap idea is clever and easy - I will probably poach the idea and apply it to mine.
I damaged the original part, it ripped off (had 3 zip ties btw). It's more for fun that I made that part, the next one I'm changing a few things... but already have a bunch of emails to buy one :lolI'm not selling them, if some one want to make a buisness of it, go ahead). As for the heat shrink it's really not that hard to remove and I have a quick link on my chain anyway... my guide, well after one ride is worn almost through... but to be fair, conditions where brutal and it's not the only part I trashed...Heat shrink wrap idea is clever and easy - I will probably poach the idea and apply it to mine.
The custom hinge I will pass on lol
Question for ya - In your write up you state that you damaged the brand new guide during the test of metal........isnt it a bit risky putting a brand new part on a bike for a race seriously though, was the part you damaged during the test the original piece, or the modified one?
