Chain Guide Help

Postby harleydh on Mon 6/Jun/11 9:03pm

Hey all I have an Giant stp I use for jumping Dh & a bit of general bush bashing with my kids but I want to upgrade a few things starting with the drive train etc.. Can i run a chain guide & still keep dual chain rings up front?? I guess it sounds dumb but I'm not overly clued up with these things .. Also what would be a good set up to get for it I want to stop the chain jumping off slipping etc but also like to 2 front gears


Cheers

you can buy dual ring specific guides such as the;

MRP - Long Range Patrol (Or LRP)
E*Thirteen - Dual Ring Security (Or DRS)
Blackspire - Stinger dual ring guide

any of the above will retain your chain and allow you to still use 2 rings

I also recommend the Blackspire Stinger. You can get them pretty cheap off Chain Reaction and they come in pretty colours .

Stinger works well, support your lbs and get it there. They don't cost much like $50-60 from memory

Stingers are good. Also look at the Gamut dual guide (p30 I think) as it's seriously light albeit a bit pricier. Speshy use them on their enduros from factory.

Have a think about whether you really need 2 front chainrings. I used to run various dual guides, but have moved to single front chain ring - lighter, never drops the chain and by careful selection of front chain ring size and rear cluster, I don't need any more gears.

Plenty of advice by others above about the options if you do decide to run dual though.

Thanks fellas went with the stinger {BB mount} bit of a mish working out fitment as getting the spacers right to keep the chain line right was a bit technical think I got it though. Seems to be sweet now had to adjust the front shifter as it moved the drive side of the crank out about 3.5mm .. Let me know if that sound wrong or anything as I said Im not complete confident on bike mechanics as I fix tractors for a living ;)

Did you remove one 2.5mm BB spacer when you installed the guide?
The guide is meant to replace it.
There may not be enough spindle for the non-drive side crank to hang onto properly.
Would be stink for it to snap off :huh:

Ummm there was only one 2.5 spacer {on the drive side} then 5/6 small shims on the non drive side. Instructions said to use one 2,5mm spacer between the stinger guide bracket & the BB cup ,I then took out 3.5mm of shims from the non drive so the centre shaft came through the drive side 3.5mm further{thats the width of the stinger bracket} My crank seems to be a little odd to other pics of seen the non drive side does not have a allen head bolt holding the crank arm on like the drive side does,it looks like the centre tube is a pressed fit then the drive end has a star pattern spline.

Christ I hope this makes sence...

if there was only 1x 2.5mm spacer on the drive side you should have taken that out and replaced it with the guide, sounds like you have a "RaceFace" brand external type crankset, they're fine
