"I've been using the Form SPD shim kit since its inception for riders witha leg length discrepancy using a 2 bolt cleat system. It's durable, reliable and flexible to use. The new V2.0 model is an improvement again and so far I've been very happy with it. Well done on engineering a great product guys!"

"Your suggestion to stack two 3mm shims was perfect! I rode 2 big rides last week and I no longer feel any discomfort to my right lower back (the side with 7mm shorter leg). This is amazing! Thank you so much!"

I recently bought a MTB shim from FORM and trust me to have a shoe that was an odd shape! I contacted FORM, hoping to be able to get a refund. Ronan couldn't have been more helpful. E-mail comms were really quick and the customer service was exemplary. FORM paid for me to send my shoe to them, they then worked on customising the shim and then paid to send the shoe back. I now have the shoe back and the shim is working really well. Customer service is really important to me and I can say this far beyond anything I've received ever. I can't recommend FORM highly enough. Thank you Ronan!

"Once I established that one femur was 10mm shorter than the other my search for a solution started. It ended when I found Form and yours should too. I shimmed the shorter leg to 5mm at Ronan’s suggestion and this completely resolved my unbalanced riding position and removed knee and saddle discomfort, still smiling about it every time I ride. Fit Form today, they work and they continue to support you. Years on and Ronan is super helpful."

"Form has helped bike fit solutions take a huge leap forward. Great innovations leave you thinking "how did we manage without it?" and this is what Ronan Descy at Form has done multiple times."

"So far the extender plates have been fantastic, actually transformative. With the new cleat position I immediately saw a 10 - 15 watt increase in my zone 2 power, and am much more stable on the bike to the point where the cleat wedges and shims I purchased previously are no longer necessary. All in all, a fantastic product—thanks for making it possible!"
