At Cykel House, we are committed to bringing you the best products at the best prices. If you find a product cheaper elsewhere, contact us via email or via live chat and we'll see if we can match that price.

We do have some criteria to meet when offering a Price Match.

  • To request a Price Match, provide the URL to the competitor’s lower price. If in-store, you can show us on your phone or a printed copy.
  • The competitor must be a UK-registered shop. All our products are brand new and genuine, therefor we cannot match prices from private sellers, auction sites, or international businesses.
  • The product must be identical to ours in condition, model, colour, and size, and the competitor must have it in stock at the time of the Price Match.

  • The competitor’s price must include VAT and delivery charges, and be listed on their website. We cannot match prices combined with other offers, including vouchers, clearance, or discontinued items.

  • Price Match offers cannot be applied after the sale is complete.

  • We cannot offer Price Matches for orders using insurance vouchers or on products purchased through finance or cycle-to-work schemes; these items must be paid in full using our usual payment methods.

  • If your Price Match is accepted, we will provide a discount code or link to complete your order. Only one discount code can be used per order.

  • All Price Match requests are subject to Cykel House's discretion, and we reserve the right to decline, alter, or withdraw this offer at any time.

Please note, whilst we can Price Match the majority of products, sending this information does not guarantee a price match is viable.

Description

Does a mechanical advantage of increased gearing sound Interesting? If so, read on.

 

Through research and testing of many different prototypes with varying amounts of Ovality we found 115% (from the top centre) to be the optimum.

 

This shrank the dead spot suitably and gave the same flawless chain retention as our round rings. The shortening of the dead spot on the top and bottom of the power curve allows you to get back into the power phase of your crank rotation sooner.

 

The benefit of this is twofold; increased gearing on the downward stroke and faster crank speed to get the crank propelled back around into the power phase continually. This is a significant gain because virtually all studies into pedalling performance suggest that a minimum 80% of your power comes from the downward motion. Mainly because much larger muscle groups are used for this motion. The physics sorcery adds extra power in the downwards stroke for no extra effort by reducing the dead spot and adds a bigger gear for the now larger power phase in the downward stroke. Win, win.
