An oversized, race-built F43 chassis paired with our CMX-tuned closed cartridge damper — built for elite control, razor-sharp handling, and unreal front-end confidence. This is the strongest, most durable, highest performance fork available.
You need to ride it to believe it. It’s that good.
BIKE FITMENT:
E RIDE PRO SR
Note: This fork also fits the E Ride Pro SS 3.0, it will feel quite a bit Stiffer on the SS 3.0 due to having heavier spring rates for a heavier weight bike. Please compare Spring rates to the E Ride Pro SS 3.0 CMX Offering
SPRING RATE CHART:
Sirris offers two weight ranges when selecting your CMX Tune F43 fork for E-Ride Pro SR. (Listed weight ranges are rider weight without riding gear on. 15 pounds of riding gear is calculated into the weight ranges)
140 lbs - 180 lbs (Medium = 4.0/4.0 springs) 180 lbs - 220 lbs (Heavy = 4.4/4.0 springs) Fork spring rates listed above are left side/right side.

My skepticism of online random ordering was ended quickly
My skepticism Of online random online ordering was ended quickly. The guys were very quick to reply to my questions and my orders were shipped next day and I had my things in 3 days cross country and delivery was made on an holiday no less.
Customer service is amazing. I originally gave them a 1 star and after working with Lance, he hooked me up with what we needed. Thank you! 5 star support.
This shop has been my number one spot for bike parts. The prices are fair, and the shipping is quick! I have yet to have a bad experience with this store, and I'm looking forward to more and more bike parts. Thank you, TB Electric team!
TB electric has been my go to online store since buying a 79Bike. Their easily navigable site provides immediate ability to check fitment on any emoto. The ship fast, great communication, and are 10-20% cheaper than any other site. Plus their videos and TalariaBoys YouTube channel are immensely helpful. 10/10 would recommend. Upgrades incoming! Thanks guys!
