Seat Problem

I weigh 280 lbs and ride a Diamondback Wildwood bike. I have two problems with an after market softer gel seat I put on my bike.

1) The seat can only be adjusted up and down with the seat stem, but can not tilt upward or downward. When I ride I feel like I am sliding forward and have to adjust how I am sitting because it feels like I slowly slide forward on the seat. Is it how my seat is tilted, or do I need to adjust something else on the bike, like raise my handlebars or something?

2) Also I have the quick release adjuster to lock in how high my seat is. I set it so that it's a the perfect height for me, but my seat very slowly seems to slide down and about a mile into my ride the seat is at a height where it's too low to ride comfortable. Would my seat slowly go down because of my 280 lbs, or would it be my quick release lock on my bike where the seat stem is?

Thanks...

You may need to tighten the quick release a bit. It should take firm pressure to close the clamp.

Can you post a picture of the seat clamp? I have never seen one that could not be adjusted. As for the seat dropping, I agree you need to put a bit more pressure on it. Or you could visit a bike shop and get a clamp that sets with an allen head bolt. I never trust the qr seat stem clamps.

Seat Problem

I have this issue sometimes, I will adjust the height and forget I have to tighten the clamp ridiculously tight. Get a rag and wipe the post of any grease you won't wipe it clean but that's ok. I've considered blue thread locking the bolt at the seat, it comes loose sometimes.

The specs for the 2013 Diamondback Wildwood Classic says it has a Alloy micro adjust 27.2mm seatpost. The Citi verson of the Wildwood says Alloy Suspension 28.6mm.

Does yours have a suspension seatpost? Still as amrmatt said, I've never seen a seatpost that doesn't have some tilt adjustment.

I just looked at photos for the 2013s and they have tilt adjustment.

Almost every single seat post has a tilt feature. The only bikes I have seen without tilt adjustments for the saddle are super cheap little tiny kid's bikes.

Your saddle *does* have the ability to tilt, you just aren't sure how to tilt it. Take picture and we will teach you how to adjust the tilt of the saddle.

Other piece of advice? Junk those awful wide gel saddles. Super uncomfortable for long rides. I'm 350 pounds and all my saddles are narrow road bike style saddles.

You sit on the sit bones not your flesh. So no matter how big you are, you want just the sit bones hitting the saddle otherwise you are in for pain.

So true, I finally got rid of my big butt saddles, anything over 2 miles became a chaffing nightmare.

My husband, a Clyde, is not a fan of quick release seat post clamps. He has switched his out for seat post clamps that tighten with an Allen wrench.

Here are some examples of saddle clamps; odds are you have one of these general types:



On this one you adjust the tilt by loosening the bolt at the bottom of the clamp. The same bolt also adjusts how far forward or back the saddle goes.

When I googled for Diamondback Wildwood there are several different bikes but they all seemed to have that type of post, with the bolt at the bottom. For example:



Yet another type is this one:

This type of clamp adjusts tilt and forward/back with two bolts, one on each side, that you can turn with a wrench.

There are other types as welll, but these are common on less expensive posts.

Seat Problem

I'd love to get a thud buster but I can't push myself to pay $100+ for a seatpost.
