Maximum Chainring Clearance: max chainring clearance

i feel kinda stupid to ask this question, so please donīt chair me if you do think so.

on the LHT page, surly site, it says, maximum chainring clearance: 38/52/56t

whatīs the difference? i mean, is 38 bigger than 22, or what? and whatīs the guideline to determine the, i donīt know how to call it, dimension of the chainring?

The largest granny and the big ring the frame can accomodate without interferring with its chain stay and keeping a good chainline are 38 & 56.

Too long for the XD on that frameset. 107-110 is what Surly recommended, the 116 would be what you'd use on an MTB frame. Get a UN72/73 or a phil.

oops, they donīt sell sugino XD around here, iīve called to shops around the country and none of them carry them, then they recommend that i get XT. would there be some problem that i use ultegra front derailleur with XT chainring?

they also donīt like tapered BB, saying that the crank is more prone to get loose after time, is that true?

Sounds like your LBS simply want to sell you some expensive components. Stick with tapered BB/crankset combo.... it won't even be an issue.

yeah, iīm getting the same felling too, iīll just order the XD online and get that UN-72/3 from another shop, in case heīs astonished with my "stupidity" and "recommending"(almost to the degree of forcing) me something "better" again.

Just make sure you torque the crankset, and it won't come loose. light coat of grease on the taper, coat of grease on the threads. I think the taper BB is at 30 ft lbs, but I may be wrong, always have to look it up. Only BB I've ever had come loose was an Octalink, and it wasn't torqued correctly. Caught it in time, and it's never been a problem since.
