Delta Cycle Bike Bicycle Stem Raiser Extender Head Up Handlebar Raiser

This stem raiser is built solid! It was easy to put on, simply mounts on top of the existing stem. You will need a 5mm allen-wrench (hex key) to tighten down the screws, plus whatever tools necessary to remove your existing handlebar. No spacers or any additional items needed. It raised the handlebar about 3" which was just right to relieve the strain on the back from having to bend over quite so far with the original stem. If you like the idea of being able to sit up a little bit straighter in order to relieve the back strain while riding your bike, I highly recommend it!

Just what the Doctor ordered! I'm not a "hard mountain rider", but I LOVE the way a mountain bike handles and feels on the streets, paths, and light trails. My only complaint (and it was a major one), was the extreme lean angle required to ride. A lot of weight and force applied to my arms and hands, made riding something less than enjoyable, and quite fatiguing. My search ended when I found this Stem Raiser on Amazon.Installation was a BREEZE, and it looks GREAT! The ONLY tool required to complete the transformation, is an Allen Wrench. Total installation time = LESS than 10 minutes!At first, I thought I might need something with a little more height, but much to my surprise, this was PERFECT! The additional height was enough to make riding a pleasure, and was well within the slack range of all existing brake and gear cabling.A MUST for fellow sufferers.I posted some pics in the pics section of the review.

The Cannondale bicycle factory whacked off my steerer tube leaving me with no cure for handlebars way below saddle level. I stewed and suffered with this for several years. My local bike shop finally suggested this Delta riser. I thought seriously about it and then dismissed the idea as being too much of an eyesore on my immaculate bike. I began to revisit the idea when I saw a photo online of the commuter bike Sheldon Brown (of Harris Cyclery fame) was using at the time of his death. The photo seemed to show a Dela riser on Sheldon's titanium commuter.I ordered one from Amazon. The Delta unit is overbuilt, in my opinion. The metal is thicker than the metal on my Richie stems. The machine work and gloss finish are both impressive. I had not expected such a carefully made product. However, it was too tight to fit down onto my aluminum Cannondale steerer. I used a tiny drum sander on a Dremel tool to open up the Delta enough to fit. No problem. I slipped on my Richie stem and measured the thickness of spacers I would need. I used a pair of carbon fiber spacers. On the bottom spacer I used the same Dremel drum sander to create a bevel which precisely fit the bevel on the Delta unit. The Delta is glossy and the spacers are glossy. You would have to be awfully picky to say the total visual effect is not good. I'm pleased that I went this route.

I'd never been able to comfortably use the drops on my road bike (2001 Cannondale R3000 Si) and after a back injury I could barely reach the tops of the bars even with a short and tall stem. While it may seem sacrilegious to racers or other weight-focused folks to add this hunk of metal to a super-light bike, I'm very happy to actually be able to ride this bike again without pain and can now actually use the drops to get back down to where the tops of the bars used to be. I haven't noticed any flexing in the riser, even when out of the saddle and cranking up a steep climb.When installing the riser, I did need to replace the star-nut in my carbon steer tube with a Specialized expansion plug since the bike previously had an aluminum steer-tube cap that filled the top of the steer tube where the stem clamps on, preventing the stem from crushing the carbon steer-tube. My local bike-shop pointed this out for me and helped me get the right expansion plug -- an easy fix.

I put this on my wife's road bike and she immediately appreciated the more upright position, even though I put her bars on the lower half of the extension. Thus far it's only been on the trainer but no problems. Two notes:1. The front brake has to be extended and this involves a new brake cable, a longer piece of housing, and rewrapping the bars. None of this is major but most people don't have the supplies in their house to perform the change. While at it, I may extend the rear brake too just in case she want's to go up farther.2. She was using a top cap mounting bolt for her phone. The top cap on this riser is a piece of plastic that threads in to the top of the riser and doesn't have any type of tension on it. The bolt is inserted before the top cap. As such, she can't use the phone mount in the previous location and I've had to change to a bar mount. Not a deal killer but something to think about.

Even though I was concerned that its 17.5 inch frame was a bit too small for me, I could not resist the price of a used 2011 Trek 7300 that was selling on Craigslist. So, I bought the bike. But alas, I had to raise the seat so high that I found myself leaning too far forward to reach the handlebars. This shifted my center of gravity forward so that my hands (rather than the bike's saddle) were taking too much of my weight. My hands hurt pretty badly during each ride. The simple solution was to raise the handlebars as well as the seat, except that the Trek manual advised that special tools and experience were needed to accomplish this. They provided no information other than instructing the bike owner to see (and pay) a Trek bicycle mechanic to do the job. Well, the Delta Stem Raiser seemed a far more practical and affordable solution to my problem. Installation was very easy (but I do have to note that the stem raiser turned out to be slightly shorter than the original stem on this Trek model...so I did have to add a 5mm spacer to hold the headset together properly). But now I can sit up in the saddle and ride the bike in comfort.
