2018 Trek Marlin 5 capacity questions

As the title implies, I have some questions about my bike...

I bought it about 2 weeks ago, and have since put just over 20 miles on it (I know, I know, not much, but baby steps ya know...)

So here's my question, according to Trek's webpage, the weight limit for my bike is 300 lbs including bike, rider & gear....I weigh 275, the bike weighs 32 lbs for a grand total of 307 lbs, not counting clothing & water bottle...so I imagine I'm closer to 312-315 lbs loaded.

Here's the bike description from Trek's page.
"Marlin 5 is a trail-worthy daily rider that's perfectly suited for everyday adventures, on and off the trail. A front suspension fork with 100mm of travel, 21 speeds, and mounts for a rack and fenders make it an ideal choice for new trail riders or anyone looking for a comfortable, stable commuter with the ruggedness of a real mountain bike."

Currently I'm just riding paved paths & streets, and I don't do any crazy jumps or silly fast downhill runs, but I wouldn't mind being able to do some easy/moderate singletrack stuff (after I've build my stamina up a bit)...the LBS said "it should be fine"...but didn't really instill confidence in me LOL!

What do you guys/gals think?

Also, I've got an old Raleigh Tamarack Mountain Tour (1985 I think), that I'm currently building into what I hope to be my daily commuter/pack mule, then the Marlin will be used on trails only.

I think you're perfectly fine. Just pay attention to your wheels - that's generally the weakest spot on bikes for heavier riders.

Thanks for the reply!

Please excuse the novice question, but what specifically should I be watching for? So far the wheels seem straight, no wobbles or anything.

Ride nude?

If anybody asks, just point to the Marlin specs, and tell them you had to save weight.

Anyway, as @TrojanHorse mentioned, you're probably fine. The specs will be general guidelines, and probably a bit conservative.

Maybe a little extra air in the tires, and be careful about what you're running over.

Replace and upgrade any parts that break in the future. Wheels?

Now that made me giggle, especially since the "World Naked Bike Ride" was in Madison last month! LOL!

Yeah, I've got them pumped up to max pressure (50 PSI per the side wall), I'm also tossing around the idea of finding some different tires that allow for higher pressures, because even at 50 PSI there is considerable sidewall squish.

Remember that there is a width/pressure thing with the tires, so narrow, high pressure tires won't help.

Wider tires at the same pressure may help some, or tires the same width, and higher pressures.

Squishing down the tires does affect rolling resistance some, but if you aren't getting pinch flats, you're probably ok.

You don't need knobby tires on the road.

Wobbles is a great thing to watch for. If you're semi-musical, you can "pluck" the spokes and listen to the tone - similar spokes should all sound fairly similar (so spokes that cross over vs under will sound different, drive side will sound different from non-drive side on the rear etc). If there is a noticeable discrepancy, take it to your shop and ask them to check it out.

If you have any spokes that are loose, you have an immediate problem that needs fixing.

Yep, I've been looking at the Maxxis Hookworms, the 29's apparently only come in one width, and are a little wider than my factory Bontrager XR2's (2.5" vs 2.2" front & 2.5" vs 2.0" rear), plus I can run the Maxxis tires @ 65 PSI too, so hopefully win/win.

And, since I'm not ready to tackle the trails yet anyway, I might as well get my miles on some street tires.

If you can find tubeless tires, and the wheels are tubeless ready, or be made tubeless ready, you could actually lower the pressure while lowering the risk of a flat. Most flats are either caused by the tube 7being pinched, or the tire being punctured. A tubeless tire has no tube, and has sealant inside which seals holes. Of course if the sidewall gets slit you are in trouble you'd be in trouble with any type of tires.

I ride on tubeless tires (700 x 28) at 75 psi with the tire max pressure being 90 psi. I'm currently 260 ish.

I had a lot fewer flats once I started over inflating my tires. I also buy the "commuter" style tires and heavy tubes. I overinflate 20% and seems to work OK
