Please note that the above geometries can be modified to best fit you as all of our frames are made to order and built in the UK - we don't charge any extra for tweaking top tube lengths or head/seat angles. Either email us your measurements or arrange a fitting (free of charge if purchasing a Stanforth bike). We can also slope the top tube to reduce standover height, as well as a fillet brazed version of this frame. Email us on either info@stanforthbikes.co.uk or simon@stanforthbikes.co.uk to discuss requirements and costs
