Choose Q103611 for maximum packing space, or the 23L model for a slightly smaller, newer design.<\/p>\n<h3>Is Q103611 waterproof?<\/h3>\n<p>Yes. It uses TPU-coated fabric and RF-welded waterproof construction. Roll the closure correctly to protect your belongings from Singapore rain; the bag should not be submerged.<\/p>\n<h3>Does this bag require a Front Carrier Block?<\/h3>\n<p>Yes. Q103611 mounts to the front of a compatible non-electric Brompton using a Brompton Front Carrier Block.<\/p>\n<h3>Can I use it on a Brompton Electric?<\/h3>\n<p>No. Brompton Electric bikes use a different front luggage mounting system.<\/p>\n<h3>Will front luggage affect steering?<\/h3>\n<p>The bag mounts to the bicycle frame through the carrier block rather than hanging from the handlebar, helping keep the load stable while steering.<\/p>\n<h2>Buy from 808 Cycles Singapore<\/h2>\n<p>808 Cycles Pte.
