A few changes/additions that I have made from stock RC Pro L that may be of interest.
Tried the Tofino saddle (more of a sit in feel) but preferred a Belcarra R1.0.
XTR FC-M9125-1 175mm crankset (to maintain 55mm chain-line with 2 x 3mm spacers on non-drive side and 1 x 3mm on drive side), 32t SM-CRM95, XTR SM-BB94-41A. Slight weight (around 80gms) increase but more reliable overall. BB easy to fit dry and no creaking.
XTR CN-M9100 chain. Best price to longevity ratio.
Shimano XTR PD-M9100 pedals. No issues at all.
RockShox SID Fender 35mm C1+/2021 V3. Needs longer bolts (12mm M3) than was supplied.
RockShox Charger Race Day 2 Damper Upgrade 3-Position Remote Lockout SID from My 2021+ (C1+) 35 mm. An overall improvement and lighter (around 100gms). The RL3 custom Charger was not locking out properly which is a known weakness for some units.
Replaced Fox Nude 5 EVOL with
Rockshox NUDE 5 RL3. No real difference in character but the remote cable is a little easier to fit on the RS.
Rockshox remote TwistLoc Ultimate 3P (I prefer it to the Twinlock) The included textured grips are excellent and easy to fit with some denatured alcohol. 4mm cable housing Jagwire 0.8mm s/s cable and barrel adjusters. 4.0mm housing fitted because
Rockshox shock/fork damper/barrel adjusters fits directly.
Shimano SL-MT800-IL seat post dropper lever. 7mm pull is fine for the new Bikeyoke Devine SL (100mm). Jagwire Pro Dropper cable (3.0mm housing).
Elitewheels 29er Pro36 carbon wheelset with their in-house Pro hubs. 300gm weight reduction and 36/60t ratchets. Excellent quality and have not needed any truing.
Maxis 29X2.40WT EXO/TR Forecaster tires. Excellent all season tire.
Replaced worn RT-MT800 discs with RT-CL900. Do seem quieter.
Shimano Optislick polymer coating on inner wire started to fray and restrict movement now replaced with Jagwire 3mm Flex SL housing and 1.1mm s/s cable. Thinner housing is easier to route and I just threaded it through the headset without disassembly.
Syncros L tool bottle and Taylor 1.0 LH. Great way to carry essential tools in included pouch.
Elite water bottle in S/S. Has a cover over the spout to keep it clean (Bought at
Decathlon).
