Will it fit?

DO NOT GUESS! TAKE MEASUREMENTS CAREFULLY - INSTALLED PARTS CAN NOT BE SOLD AS NEW

 Know these 3 things to determine fitment.

1.  FRAME LENGTH - most important!

        METHOD A - Tension Point Attainment - Simple!

                1)  Loosen eccentric, remove the chain, so it will rotate through the complete adjustment range. 

                2)  Measuring between the 2 bottom bracket axles. Are you able to attain one of these numbers? 706mm, 726mm, 729mm, 739mm.
 
                If YES, proceed to Step 2 OR further verify the frame length via Method B below.

                If NO, stop here as there is no belt system that will fit, there is no need to call asking if it will fit a 704mm, 724mm, or 737mm maximum dimension. The answer is still NO, a Gates belt system will NOT work.

        METHOD B - Adjustment Range - Best Way!
       
Write down these 2 dimensions (your frame length range).

                1)  Measure from bottom bracket center to bottom bracket center in millimeters 
                with the eccentric in the loosest possible chain position.

       
        2)  Measure from bottom bracket center to bottom bracket center in millimeters
                with the eccentric in the tightest possible chain position.
      
                 3) Do one of these FRAME LENGTH numbers,
706mm, 726mm, 729mm, or 739mm, fall between the 2 numbers within your adjustment range? 

               
If YES, proceed to Step 2.

                If NO, stop here as there is no belt system that will fit, there is no need to call asking if it will fit a 704mm, 724mm, or 737mm maximum dimension. The answer is still NO, a Gates belt system will NOT work.            

2.  CHAINRING BOLT DISTANCE  
        Measure from one chainring bolt directly to the next. Is it near 2.5" or near 3"

3.  NUMBER OF CHAINRING BOLTS  
        Count them. Do you have 4 or 5 on each spider?

4.  FIND THE CORRESPONDING GATES SYSTEM BY APPLYING THE INFORMATION ATTAINED TO THE CHART BELOW.

            Find FRAME LENGTH in the 1st column, match to your chainring bolt spacing and the number of bolts in the 2nd column.

Order the appropriate system using the assigned Kit Numbers, i.e., 706-5-SST+.

2-4mm longer is ideal!

5.  INSTALL KIT
        The install kit is required for all 5 bolt systems to insure proper and safe sprocket to spider engagement allowing for adjustable optimal alignment while insuring tight chainring bolts. $50 - 10 bolts, 20 locking spacers, and Torx tool, included.

6.  GATES TENSION TOOL
        Highly recommended, insures proper Gates tension spec. $50 with a complete system. Phone apps proved to be unreliable, not repeatable, hence the tension tool.

7.  SPARE BELT
        Most opt to have a spare on hand like chains, cables, and tubes. They weigh virtually nothing, should always be carried when on a tour or when at an out of town event. $90 with a complete system.

8.  FITMENT
        The system WILL fit when measuring instructions are followed, unless an unknown clearance issue surfaces. We have never seen one but.....

9.  ORDER
         Bottom surfing is alive and well. We guarantee the lowest price and price match, if a concern. Most value the research, experience, tandem promotion, and sharing of knowledge, and refrain from information mining, to only purchase elsewhere. As my daughter's would say, 'please don't be one of those people'! Thank you for purchasing from us.
