Hi,
Is it possible to convert my triple chainring to a double by removing the largest ring? Also thought about fitting a bashguard. Its a shimano deore triple as found on the RR8.1 http://www.decathlon.co.uk/81-2012-id_8168918.html.
If its possible, what do I need to buy to do it, and would a DIY job be cheaper than just buying a double?
Cheers

Yes just remove the ring and set the high limit screw to stop the mech moving too far. You'll need either a bash ring or shorter chaining boltsI don't do smileys.

It'll cost less than a tenner and take less than 10 mins if you just buy shorter bolts. What are you hoping to achieve though?
(You can do it for free if you convert your big ring to a bashguard by taking the teeth off with an angle-grinder). But unless a bashguard is your reason all you have done is reduce your gear range for the sake of a few grams0 -
My reason is trying to improve ground clearance. Is this a good enough reason?0

will give you not much better clearance.
what are you riding that get the rings catching?"Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Gain in clearance will be less than an inch from circa 5.5" on a typical bike (about 12.5" BB height) to 6.5" assuming you don't then run a bash which will then claw back upto 1/2".Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0

So why is everyone going to a 22/36t double and bash then, if it makes no difference to clearance? It seems to be the most commonly cited reason. Is it just to be cool? :?0

Oh, I may not do it then. That was my only reason. I never use the big ring.nicklouse wrote:what are you riding that get the rings catching?
Nothing in particular, but for some reason its always on my mind when taking any sort of moderate (rollable) drop / step. Its been this way since I came off on the degla skills section a couple of months ago (caught my chainring on the level 3 rock drop off and hurt myself quite badly).0 -

I run a guide rather than a bash. would not really want to clober it on a rock as it would not hold up to much.
infact i have rarely cought a bash on anything.
Oh and the Hammershmit was just to be cool :P"Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

My local rides involve frequant hoiking of bikes over fallen logs, so a bash gives me peace of mind against bending/breaking a chainwheel tooth off.Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0
