So I’m looking to add a chain guide to my 2019 CruX because I’ve dropped the chain both to the inside and outside multiple times while racing (and just riding along). It is the completely stock Rival 1 setup so I’m not entirely sure why I’ve had these issues. It seems to occur when rapidly moving up…

I’ve been very happy with the braze-on version of this: [image] GnarWolf Chainguide with Seat Tube Clamp Mount If you are a 1X CX, gravel, or road rider and can't afford to drop a chain, the Wolf Tooth GnarWolf® seat-tube clamp chainguide is for you. Designed specifically around 1x wide/…

I’d look at your setup, a 1x rival with a narrow-wide chainring shouldn’t be dropping chains. Maybe the chain is too long, the rear mech out of alignment, or the BB wonky?

@splash has a good point, my mtb (albeit one with 140mm and fat tyres) has never dropped her chain and that is over much rougher and/or worse conditioned surfaces. If you do end up using one the Kinesis one looks good, tbh though all of the top only ones look pretty similar so pick the one that cat…

[image] neva6: 2019 CruX That seems odd. Check a few things: Rear derailleur bolt where it connects to the bike. Is there slop laterally away from the bike frame? It should be tight against the bike. Is the rear cage bent? Are the jockey wheels bent/messed up? Chain, is the chain master lin…

I find that after a seasons use, I’ll start dropping chains a lot. It’s because the chain and chain ring get worn out and everything gets a bit sloppy, thus the chain falls off easier. I’ll often put a new chain and ring on mid cx season so that I can trust them in the big winter races. Chain guid…

Thanks for all the insight. @splash @firemunki I agree. I can’t remember a time I dropped my chain on my 1x mtn bike in 5 years. I will look carefully over the bike to see if there are any issues that you highlighted @jfranci3 . I only have about 1000 miles total on the bike and that is across 2 ch…

I find chain guides more of a hinderance than a help. The last time i dropped a chain in a race, i spent longer than i shouldve had to, wrestling it back past the chain guide to get it back on the chainring. It wouldve been a much easier and quicker fix if there was no chain guide. Best of both wo…

I wouldn’t put one on my cx bike, it’s just an extra thing the mud/grass/leaves will clog up. I want as much clearance around the moving parts in my bike as possible. Other people may ride in different conditions though, where that isn’t a concern.

I wouldn’t use a guide. It’s another spot for mud and debris to accumulate. Plus if you drop your chain with that guard on there, getting the chain back on during the race is going to be a PITA. As others have said, examine the setup on your derailleur and chain length, and get a second opinion from…

I mean what came on the bike from the shop as purchased. I haven’t counted the exact links but it looks to be about right.

I’ve been very happy with the braze-on version of this:

I’m sure the clamp version is just as good.
