Does not fit modern mountain bikes with seat posts
358623
Not designed to fit modern mountain bikes. Tried to installed this on a front-suspension Trek mountain bike and the metal bracket that is supposed to line up with the two metal rods on the underside of the seat do not line up. It is off by a little, and while I could have tightened it down real hard and probably gotten it to stay on, I was concerned that it would pop out at the worse possible time. So I returned it.

Note, that mountain bike have seat "posts" and as such they do not have a cylinder that can fit into the hole at the bottom of the seat. Instead they have to be attached via the bracket, which unfortunately doesn't fit.

The seat is very soft and likely works well for cruises, city bikes and other kinds of leisure bikes but did not work for me.

If your bike has fenders, beware.  The clamp that holds the bike post is too big to fit between the post and fender . . . and will not clamp on a smaller post; like the seat post.  Otherwise, the product is hefty enough for my repair and cleaning purposes.

I bought this basket for the front of my Trek 520. It's a nice basket, but doesn't fit in my narrow handlebars. Deducting two star for this - I wish Wald made a front basket that fit all adult-size dropbars.

If you're a short person with narrow (38cm) drop bars, this won't fit on your bike. Your height means that it will be vertically positioned inside the handlebars, but the basket is too wide to fit there -- it interferes with the brakes. If you are taller, or use wider handlebars (even 39cm would probably work), you'll be fine.

Doesn't stretch enough to fit over the seat of a size Large men's Kona 29'er. One size does NOT fit all mountain bikes. Description is misleading.

Well built but didn't fit my bike ... Keeping this until I find the right application

I like the medium wedge bag and have used one for years on my primary road bike. I don't know when the change was made, but, the current version has a different design for the seat mount. The old mount clamps to the wide section of the saddle rails toward the back. The newer version clamps to the narrow section of the saddle rails where they are parallel. My saddle would need to be moved all the way to the rear to leave enough clearance for the quick attach mount. Unfortunately, this new seat rail clamp makes the bag useless on any of my four bikes.

I really wanted to love this review, but the unfortunate reality is that two road bikes do not fit on this rack if one of them has a trunk rack attached. It's a well built rack with lots of great features, but the handle bars of the second bike get hung up on the trunk rack and there is no way to work around it because the placement of the straps is not adjustable. If you are only hauling one bike, this rack likely makes a lot of sense. Unfortunately, I have to return mine.

Great product but doesn't fit 11 speed bikes as advertised.

doesn't fit Specialized brand hybrid bought from local bike shop.  Not enough room to unbolt, add, then rebolt unless I add a spacer, and that might throw off the rest of the rig.

This item seems well made but doesn't fit either of my Trek bikes and for the price it is not worth returning.  :(

very nice seat comfortable and easy to take it of the rack but be aware not for all bicycle. You must have some skills to make it work especially if you plan to use it with a mountain bikes!!!. Amazon shipping is fast.

This is a very well built seat cover.  However, it does not fit the full size seats on mountain bikes.

I attached pics of this seat cover when I was trying to fit it to my mountain bike.  Not sure why they advertise it as universal.  It is not.

However, this does not take away from the quality of the seat.  It's a well built seat cover.

Of course, with Amazon's excellent return policy, I was able to return it at no cost to me.

Edit: Seller has offered a refund for the product no questions asked since the post did not work for my bike - this is amazing customer service. I will not return the post and have instead used it on my road bike, where it is working amazing. This post still will not work with slack seat tube angles, but you purchase is safe with the seller.

Post is good quality, however one big flaw depending on the type of bike you have - this post will not work with bikes with slack seat tube angles. On bikes with highly angled seat posts, the double screw adjustment does not move far enough and even at the max adjustment the seat will still point upwards. This post will not work on any of my bikes which are all all mountain hard tails - a Kona Honzo and Canfield Nimble 9.

I didn't want to leave a 3 star review because I am certain this post will work well for XC type bikes, but I want to make sure others know this post won't work on certain bikes.

the adapter is well made.  it didn't work out for us.  between the seat post moving rearward and the seat surface moving upwards, my wife couldn't reach the pedals anymore.  it was almost 5 inches of leg-length increase.  if you use your bike with the post almost all of the way lowered than this is not the right option for you.  measure twice, buy once.

I have a 27.2 seat post, and I bought a cannondale frame designed for a 31.6 post. Easy and clever solution at a very reasonable cost. The best and most important part of the deal: It worked perfectly.

My mistake for assuming that the width was common and that this would fit a mountain bike wheel.
Keep in mind this is only 11mm wide.

I have a Giant TCR Advanced 2 full carbon bike that i purchased this item for. It has good reviews for being bright and reliable. While it is bright and eye catching, it comes only with a tubular mount for round shaped seat stems. the seat post on my giant, as many other higher end road and tri bikes the seat post is oval or triangular for aerodynamics. there is almost no way to mount it and i am going to have to rig something up so i can make use of my spent $!
