I would recommend this only because its this or fashion one for yourself. It does its job - 400 miles on it hasn't moved. That said its a bit Mechano, basic and poorly thought out as a solution. Not for the weight conscious but does its job.

Used for getting mudguards to clear disc brake
Got these with the idea of using them to mount a tubus rack that had issues clearing the rear disk brake (on a fuji sportif to be precise). It didn't work out for the rack but it worked fine for mudguards suffering the same mounting issues
If you are going to use these to extend a rack it will give you a bit less than an inch of extra length on the bottom mounting point of the rack. Probably not a whole lot distance but it might prevent heel strikes on your panniers if your cadence tends to graze them.
The piece is quite solid (about 2mm thick) and adheres to your tubus frame with two bolts (with the third hole mounting to the bike frame). It doesn't look as though it is likely to jeopardise the structural integrity of a pannier rack. However if you are working with a non tubus rack (ie one that doesn't have two mounting holes an inch apart at the bottom of the rack ) it probably will jeopardise the integrity.

These moved my Tubus rack higher, out of the way of a fatter tyre than recommended.
Fantastic quality parts and fixings.

If you want comfort against heel strike
As others have said, you don't get a lot of movement for your money but you do get some and I was paranoid about the problem having size 12 and a half and up to 49 euro feet so fitted it without trying the rack without the extension. He presto no heel strike!
The rack itself comes with all the fixings so you don't need to buy this for them. Don't be a silly fool like me and use the long bolts which then go into the space occupied by the gears so you can't change into the low numbers!

A cheaper alternative to the L-shaped bracket
i bought this to fit a Tubus Fly rack to a racing bike without lugs.
These bolt on the bottom of the rack and you use a longer (MTB) rear quick release to secure them.
I actually only used one bolt so that the bracket ran horizontally as my drop-outs have shoulders meaning they are recessed from above.
With a bit of fiddling and mongering these fit and hold the rack on perfectly well even with some heavy one-sided pannier loads communting on rubbish London roads.
The downside is that the bolts in the back are rubbish, I ended up using my own as they just didn't tighten properly.

It does what is should do.
It does what is should do i.e. fits a rack to a disk braked bike.

Needing a touch more heel clearance this product gave myself just the right amount not to catch the rain covers when riding in the rain. The instructions are easy to follow plus riding on rough tracks and cross country the item has performed A O.K.

Helped a bit
Bought this to move my Tubus Logo rack up and back and while it does the job, it only really moves it 15mm at 45 degrees at the most. This was enough for me to avoid clipping my heel on fully loaded Ortlieb panniers though.

Does the job
Did exactly what I needed it to - let a Cosmo rack clear the disc caliper on a Trek 4300 disc (2011 model, size 21" / XL). Time will tell for durability, but seems well made. Photos say the rest.

I occasionally use a rear rack on my hard-tail mountain bike to carry camping gear so that I can camp in remote parts of Scotland and climb Munros and Corbetts. The frame came drilled for a rack and for disc brakes, but had V-brakes fitted originally.
After a few years I had disc brakes fitted to my (lovely) titanium frame, but I discovered that the Tubus Fly rack no longer fitted.
Dismay: I had no wish to carry all that stuff on my back.
Joy: the Tubus Rear Rack Extension cost just over £5, arrived promptly, did not challenge my limited skills with nuts and bolts, and works well giving good clearance for the tyres. So more Munros and Corbetts...

This doesn’t move the rack as much as you might hope, and as you have to attach it with a nut and bolt you might then have an issue with these getting in the way. But, the kit seems solid and good quality, so if it does work for you, I think it would be great.

I got this to go with my Tubus Vega rack but I was happy to find that I didn't need it as the rack came with all the bolts and spacers needed.
I think you'd only need this is you had disc brakes or mud guards fixed in the way.
Quality wise, it looks great, but is quite pricey for what it is.

Absolute must for Tubus racks
This kit is a must if you buy a Tubus rack. Save time and order one when you order the rack.

Tubus Extension kit
This little kit does the job perfectly, converrting frames without mountings to carry racks. It takes a small amount of fettling to get right, but can give an old faithful racebike new life as a tourer/ commuter- smashing!

Assisted me in fitting the rack to my bike with disc brakes. Some modification was required but it was an easy install.

Essential rack part sold as extra
If you bought a Tubus rack, you'll probably need this Tubus rack extension kit too, regardless of whether your rack actually fits. My very expensive Tubus Cosmo rack came with a fitting kit that had no nuts to the bolts. To get the nuts, you have to buy the extra-cost fitting kit, see? It looks like some cost accountant studied the parts of the rack and decided to split out the fitting kit as an extra profit centre. It is shameful for Tubus not to supply a proper fitting kit with their racks, to make you pay extra. However, once you have bought the fitting kit, you have enough nuts and bolts to fit the rack, and a very nice quality of stainless bolts and nyloc nuts they are too, complete with stainless washers and quality plastic spacers. But such a shame necessary parts are extra.
If you actually need the extension kit to raise or move backwards or level your Tubus rack, you might be disappointed. The extension piece, while stainless and nicely finished, is disappointingly short and fits in only one position, with just about zero wiggle room because the struts of the rack brace the extension bracket between them. As a result my rack is fitted with a slightly forward tilt. However, the bracket, once bolted down between bike and rack, has not the slightest sway in it. The whole affair is competently designed and mounts rock-solid.
If the fitting kit had been supplied with the rack, as it should have been, I would not have complained. But to be made to pay extra for necessary parts is shameful, and strictly as an extension kit this one falls a bit short of necessity.
Especially if you have a 29-er or other fat-tyred bike, you might want to consider buying a standard drilled mild steel straight bracket at your hardware store instead and getting a little more rise on your rack.
I can't recommend paying extra for a packet of necessary nuts not supplied with the main rack!

Bought this with my Cosmo Rear Rack. Needed to have some extra clearance to mount my struts for rear mudguard.Worked a treat and did not change the original design configuration much , if at all.

I've got a pannier rack on my road bike that I'd like to fit to my MTB. However, the MTB has discs and the rack won't fit to the dropouts as the caliper is in the way. Would this be suitable to enable the rack to fit?
