MRP and Ibis have designed two custom
single ring chain guides for the Mojo HD
and Mojo SL. They are called the G3 SL
and the Lopes SL. Both mount directly
to the frame via the bottom bracket and
the main pivot shaft. This fixes the guide
in place so it won’t rotate. The pivot
shaft on the HD is already drilled and
threaded to accept either guide. For the
Mojo SL, we make a special main pivot
shaft that facilitates mounting of either
chain guide.
If you’re converting your triple crankset
to be compatible with either guide,
we recommend a non–ramped replace-
ment chainring (34 and 36 tooth rings
are available in our webstore.) To do
this conversion you should start with a
triple crank and remove the inner and
outer rings. Double cranks do not have
the right chainline to make the guides
work.
The G3 SL is designed for a 32t–36t
single chainring and features bash pro-
tection as well as chain retention.
The Lopes SL will accommodate chain-
rings from 32t–38t. (34 and 36 tooth
rings are available in our webstore.)
Dual Ring Guides
The Ibis/MRP 2x dual ring guide works
on the Ibis Mojo HD and Mojo SL (and
is not compatible with the Mojo SL-R).
It’s available in our online store: http://
store.ibiscycles.com/product166
This guide will work with:
• SRAM 2x10 cranks with a 26/39 or
28/42 ring combo, using a SRAM
dedicated 2x10 front derailleur.
• Shimano 2x10 XTR/XT cranks with
a 28/40 ring combo and a Shimano
2x10 front derailleur.
• Shimano 2x10 XT cranks with a
26/38 ring combo and a SRAM 2x10
34-38 front derailleur. (SRAM X.0
2x10 38/36t High Direct Mount Dual
Pull Front Derailleur).
NOTE: MTB triple cranks down convert-
ed to a 2x10 (in the middle and granny
positions) won't work with the 2x guide.
This also includes the XTR 26/38 combo
(which is built on 3x spacing).
To mount the guide, use the 1mm (extra
thin) BB spacer provided with the guide
between the BB shell and the guide,
then a 2.5mm BB spacer between the
guide and the BB cup. Use the provided

Chain Guides
M8x12 bolt to bolt the guide directly to
the main pivot shaft on the front triangle.
Use blue Loctite on this bolt.
On a Mojo SL, replace the stock main
pivot shaft with a "Mojo SL-MRP Chain-
guide Adapter" pivot shaft available
from our store:
http://store.ibiscycles.com/product120.
Then attach the guide to the main pivot
shaft with the included M8x12 bolt.
Spacing on the HD and SL is identical.
Single Ring Guides
For you 1X10 lovers, we’ve found that
Shimano’s Shadow Plus and SRAM’s
Type II rear derailleur virtually elimi-
nates the need for the lower half of
your chain guide, while making your
bike nearly silent. Both derailleurs
provide heavier chain tension plus a
friction stabilizer to dampen the cage
and thus chain movement (chain slap),
which dramatically reduces derailing
of chains. Combine either rear derail-
leur with an e*thirteen XCX-ST D-Type
or an MRP 1X upper guide and you
should have very few chain issues.
