The "+4mm" option indicates that the pedal spindle is extended by 4mm compared to the standard or "normal" length. This extended spindle length can help provide a wider Q-factor, which is the distance between the pedals' attachment points on the crank arms. A wider Q-factor can offer some riders improved stability and better biomechanics. On the other hand, the "normal" option signifies the standard spindle length without the extra 4mm extension. This is the default length that most cyclists would use. Your choice between these options should be based on your individual body proportions, riding style, and preferences. If you're unsure which option is best for you, it's a good idea to consult with a bike fitting professional or a knowledgeable bike shop staff member to get personalized advice. “+4毫米”和“正常”可能是您指的关于Shimano R8000踏板的轴长度。 “+4毫米”选项表示与标准或“正常”长度相比，踏板轴被延长了4毫米。这种延长的踏板轴长度可以帮助提供更宽的Q因子，即踏板在曲柄臂上的连接点之间的距离。较宽的Q因子可以为某些骑手提供更好的稳定性和更佳的生物力学效应。 另一方面，“正常”选项表示标准的踏板轴长度，没有额外的4毫米延长。这是大多数骑行者会使用的默认长度。 您在这些选项之间的选择应基于您的个体体比、骑行风格和偏好。如果您不确定哪个选项对您最合适，最好咨询自行车定位专家或了解自行车的专业人员，以获取个性化的建议。 Can Whatsapp / Call . https://wa.me/60126960321 Vince . https://wa.me/60126105929 Shop . office 03-8060 8967 Operation Hour Monday to Saturday (10.30AM TO 7PM) Sunday Close ---------------------------------------------------------- SANTA CRUZ (VK CYCLES PUCHONG) Map - https://goo.gl/maps/8y79tAyzkEE2 (LOCATION) No 39, Jalan BP 7/2 , Bandar Bukit Puchong, 47100, Selangor , Puchong Facebook - https://www.facebook.com/SpecialistRepairBicycles/ Instagram - VK CYCLES PUCHONG Buy on shopee: VK CYCLES PUCHONG https://shopee.com.my/product/78112047/1501451708/ Buy on LAZADA: VK CYCLES PUCHONG https://www.lazada.com.my/products/i3121622605.html?spm=a1zawi.24863640.table_online_product.41.90e04edfWTs8EW Buy on Tiktok: VK CYCLES PUCHONG https://shop.tiktok.com/view/product/1729610414280640694?region=MY&locale=en
