[FONT=Lucida Grande]переводить лень. Если коротко: лапка от Deore LX 10-speed RD-T670-SGS подошла к 105-му переклюку.
А для того, чтобы переклюк смог прожевать звезду 40, болт B-tension был поставлен задом наперед, тк не хватало длины. Фотка по ссылке!

Seems like there’s a lot of interest in 10- vs. 11-speed as well as road vs. mountain group compatibility. I just completed a mix/match combination I think your readers would like to hear about. I have a Giant AnyRoad CoMax with Shimano 105 11-speed group. The bike has a compact 50-34 crank and 11-32 cassette with 32mm tires from the factory. After taking a group trail ride with mixed cross and mountain bikes, I soon discovered the climbing/traction limitations of the factory tires/gearing in a mountain bike environment. I wanted to be able to swap between wheelsets with 32mm cross tires to as big a tire as I could fit in the frame with even lower gearing. The 11-32 cassette is the lowest geared road 11-speed cassette available, and I didn’t want to change to a mountain bike crankset. The solution, it seemed, was to use the XTR 11-40 11-speed cassette. I purchased a used Giant mountain bike 10-speed wheelset and mounted a Panaracer Firecross 45mm tire on the front and a Bruce Gordon Rock-n-Road 43mm tire on the rear.[/FONT]
[FONT=Lucida Grande]Since the XTR 11-speed cassette has the same hub width as a 10-speed cassette, it mounted to this new wheelset without modification. With a 50t chain ring and 40t cog, the stock 105 medium-cage rear derailleur wasn’t up to the task of taking up that much chain, and the long-cage mountain-bike derailleurs have a different pull ratio and are therefore incompatible. Also, there isn’t a “B” screw long enough to keep the upper jockey wheel from rubbing that 40t cog.[/FONT]
[FONT=Lucida Grande]What I needed was a long-cage 11-speed road derailleur. After examining the exploded views of the Shimano road and mountain-bike rear derailleurs I found, it appeared, the long cage from a direct mount Deore LX 10-speed RD-T670-SGS mountain-bike derailleur would interchange with the 105 medium-cage. I purchased a used Deore RD-T670-SGS, removed the cage/P-tension spring, removed the 105 cage/P-tension spring, and, sure enough, the mounting/pivot pins are identical. I installed the Deore long cage/P-tension spring on the 105 and now have a long cage 105 11-speed rear derailleur.[/FONT]
[FONT=Lucida Grande]Prior to my rear derailleur “hack” I would switch chains when I would switch between wheelsets. Also, I reversed the “B” screw, had it adjusted all the way out, and had to install a spacer between the screw and derailleur hanger to prevent jockey wheel rub.[/FONT]
[FONT=Lucida Grande]The Long Cage 105 derailleur “hack” solved two problems:
1.) I no longer have to switch chains when switching wheelsets; the long cage easily handles the longer chain.
2.) The upper jockey wheel on the Deore cage is offset slightly away from the cassette compared to the 105 cage. This allows an almost normal “B” screw adjustment even with that big 40t cog.[/FONT]
[FONT=Lucida Grande]The time it takes to swap cages/P-tension springs is about 30 seconds (not including chain) and for me was under $30. I haven’t priced just the cage from Shimano but these Deore derailleurs can be found used for cheap. I can cross chain 50-40 or 34-11 with no issues and it shifts flawlessly. Best of all, since it’s factory Shimano parts, it doesn’t look like a hack; it looks factory.[/FONT]
