Good bike for the price. Best cost vs. Benefit
I ordered my Wilson clash 100 pro from Kunstadt. And received in 4 days. Very efficient.
Fast delivery, exactly what I wanted. The price was cheaper here.
I started skiing last year and jumped into these this season by recommendation from Kundstadt. They are absolutely wonderful to steer, not as rigid as the expert ones, and they give me excellent control, short stopping and turning capabilities, while letting me go as fast as I want. I tried other models renting and so far these are the best. I'm smiling in the picture.
I'd toppled over this morning and, well into my ride, realized I'd knocked my front brake cable out of its housing. I brought it into the Bank and Heron location and met Eric. He mended the brake, then went on to clean my very dirty chain, adjusted my rear brake and gear mechanisms and sold me some chain cleaning fluid - all in good humour and in short order. I flew home on my now very happy bicycle. THANKS, ERIC!
My son 18, who the skis are for has been sleeping with them since they have arrived! Too early to try but they look and feel good! Awesome graphic's, light weight.
Cheers, Brian
I've purchased two bikes from here, and had my bike, skis and tennis racquet serviced here. Nothing but great service and prices!
Best price I could find and super quick delivery. A++++ for Kunstadt
Great purchase! Love the look and feel of these classic Fischer boots! Kunstadt Sports was quick to respond to my inquiry and even quicker to ship out the merchandise - awesome transaction - thanks Kunstadt!
The jacket is perfect for the spring and summer.
Bonne qualité et très bon produit
Absolutely great company to deal with
I even was able to change the size after placing my order, real customer service
Most precise high performance boot I have ever skied. For a plug boot it is surprisingly comfortable. Body movements are transferred to the skis with precision and quickness.
This is probably the most comfortable ski boot that I have ever tried on! The design is superb!! I wish that I had tried the Fischer boot long ago. Better late than never!!
However, I need to try one size smaller to clarify that this is the boot that I can keep.
Good retention, transmission and responsiveness on a number of different snow conditions. Still a little difficult to get out of at the end of the day but does not freeze up with changing temperatures and wet 'powder' conditions.
