Tracer VP 1x9 Guide Options

The new VPP 2 system has the lower link sitting more vertical than the old models. This can be a bit of an issue with mounting a guide up but both will work fine, E-13 and Intense have always gone together until last year and now MRP is what you see a lot on there web site. I belive that its more of an issue involving MS racing ..... I have set up both guides and you do have to rotate them back around the 11 oclock to 10:30 potion. This will help clear the plastic taco from the lower link. I would go E-13 but I am bias. One thing to do with the E-13 lg1 plus is to run the back plate in the wide setting this will help clear the swing link with out having to affect chain line. What is nice about the XTR cranks is that the grany ring tabs are not as thick as other cranks so you will not have to grind them off.

If you go to the Tazer photo thread you can see my bike with the LG1 plus, The bike is the first one in the thread and you can see how it sits it will be the same as how it would sit on your tracer since both frames are very similar in build minus geo

So I'm currently building up a new VP, and planned to run a single 36t with my XTR crankset. I would prefer to use the ISCG tabs and don't want a full bashring...that leaves me with 2 options that I could find. MRP G2 mini / E13 LG1+.
Based on the Intense website saying MRP is better suited for VP's I went with that. I tried every possible option with spacers, but could not get it to work without rubbing on the bottom link, or creating a terrible chainline.:madman:

Has anybody ran the LG1+ or figured out how to mount the G2 with the taco and lower pulley? Or should I just wait for the new LS1+ next month?

Thanks

Good luck with that one. It's like trying to solve Fermat's Enigma.

(On my non-ISCG Tracer VP) I tried the SRS+ with little luck in the 'wide' setting: threw the chain line way out of whack and I couldn't get it rotated far enough to actually put any tension on the chain other than in the biggest 3 cassette cogs-but again, the chain was coming off the chainring at a crazy hard angle. I choose the SRS+ as the lower plastic body wasn't as large as the LG1+ and I figured it may help it in clearing the low chainstay.

I ended up using an MRP 1.X guide seated against the BB and a Black Spire Stinger sandwiched between the 1.X and the BB. I had to modify the Stinger swingarm to allow for a smaller profile bolt head to sit flush and not hit the lower linkage. Not super ideal, but it worked and the chainline wasn't AS jacked up.
With MRP and E.13 coming out with seat tube mounted versions later this year, using that set up along with a Stinger will bring the chainring back in line as you won't be using 2 BB spacers (width of both the 1.X and Stinger)-so to speak.

Sounds like a cluster f#ck, but it actually worked extremely well and didn't look bad after it was all lined up. I was able to get more than enough tension with the Stinger underneith and the 1.X up top kept the chain from coming off when back pedalling. And it was a lot quieter than the SRS+. I added a half an inch of Frame Wrap around the lower 1.X body to keep chain slap noise down to nothing.

You can run the above set up with an SRS+ bashguard if you remove the outer plate of the 1.X guide. I used the bolt that holds the two peices together and again wrapped it in Frame Wrap to keep noise down and to lessen the gap between the inner 1.X body and the bashguard to keep the chain from slipping down and getting jammed.

I have to say that the Tracer VP and chainguides is a sorry story. I beat my head against the wall for months trying to get something to work, but that lower linkage is just too wide and the chainstay drops way too low.

All in all the frankenmodded crap I put togther above wasn't terribly expensive: $75, a trip to the hardward store to buy a bolt, and about 10 minutes with a Dremmel hitting the bolt slot on the Stinger.

However, given how jacked up Intense designed the lower part of that bike, you may be better off nixing the ISCG mount versions and going with a straight up BB mount Stinger if you decide to try this. I would imagine that you may run into an issue of not being able to rotate the Stinger far enough to get any tension. But that's just speculation.
