Spcycle R088

Many builders report the front derailleur mount is misaligned, causing poor shifting or chain drops. Solutions include shimming with materials like credit card pieces, rubber strips, or PPF film behind the mount to correct the angle. Some have carefully bent the mount or used washers.

Headset play is a frequent issue, often due to the stock expander plug being too short, incorrect C-ring height, or improper bearing preload. Solutions include replacing the expander plug with a longer one (e.g., Cane Creek Ancora or Deda 70mm), sanding down the C-ring, using microspacers, or ensuring the fork steerer is cut to the correct length.

Yes, the frame supports mechanical groupsets via a braze-on front derailleur mount and internal routing. Builders note cable routing is challenging, especially with integrated handlebars, due to tight spaces around the bottom bracket and handling multiple cables. Recommendations include routing cables before installing the bottom bracket and using separate stems/bars for easier builds.

The frame uses a BSA threaded bottom bracket. Common choices include Shimano Ultegra BBR60 for reliability, ZTTO ceramic for budget options, or SRAM DUB with appropriate adapters. Builders recommend ensuring proper spindle length and using spacers as needed to avoid chainstay interference.

The seat tube can be tight for batteries. For Di2, some sand the internal ridge or use zip ties to create a pull tab. For LTwoo, the battery holder often fits snugly; use ribbon string to retrieve it, and cutting the seatpost may be necessary on smaller frames.

The stock seatpost clamp can become stuck, making adjustments difficult. Users report needing to tap it with a rubber mallet to loosen it even after unscrewing the bolt. Applying assembly paste (e.g., Dynamic Assembly Paste Pro) inside the clamping area can help prevent sticking, but some prefer aftermarket seatposts with different clamp systems for easier adjustments.

Some users report slight front wheel 'jumping' during hard braking, which may be due to new brake pads or discs needing bedding-in, rather than headset issues. To check, ensure no headset play by bouncing the bike while holding the front brake, and test for movement with both brakes applied while stationary. If headset is tight, the jumping should diminish with use.

The frame is commonly purchased through Aliexpress or by contacting the seller directly via email. Users report good communication and after-sales service through these channels. Aliexpress links are often shared in forums for convenience.

Users report that Continental GP5000 tires in 30mm and 32mm widths fit well, with some suggesting 34mm may also be possible. Mixing tire sizes (e.g., 28mm front and 30mm rear) is feasible and unlikely to noticeably affect handling. Real-world testing indicates the frame can handle up to 34mm tires, though 35mm may be tight.

A rhythmic knocking sound while seated and pedaling can be caused by several factors: drive-side crank arm rubbing against the front derailleur, crankset axle play, loose thru-axles, the Di2 or LTwoo battery knocking in the seat tube, or the seatpost clamp. Solutions include checking and tightening crankset components, applying grease or carbon paste to the seatpost clamp, and securing the battery. The sound often disappears when standing due to reduced frame flex.

Some users report a wobbly or flexy feeling from the handlebar area, especially with integrated bars. This can be replicated by applying force to the bars and is similar to what GCN showed. However, many riders find it does not affect actual riding stability and is common among lightweight frames. Using a longer expander plug or separate bar/stem may reduce the sensation.

The stock seatpost wedge may not fit perfectly, and the seatpost cover is considered low quality. Some builders recommend replacing them with SL8-compatible parts for a better fit and finish.

Yes, the frame can accommodate tires up to 35mm measured width (wam) with minimal clearance. One user reported a 35.5mm wam rear tire fit with a couple of mm clearance, but it's recommended to test with tape on chainstays to check for rubbing.
